>>538092663What will gypsies steal anymore, think of the gypsies.
China’s massive urbanization and infrastructure buildout consumed nearly half of the world's copper supply, causing prices to skyrocket from under $0.80 per pound in 2003 to over $4.00 per pound by 2006.
>>538092663its same shit for wiringaluminium is cheaper, weights less, somewhat worse conductivity so you just need wires that are somewhat thicker.Literally same shit in cars/homes
>>538092663Doesn't aluminum melt easily?
Too, you dumb nigger
>>538093761Not if it's grounded
>>538092663Makes sense.>>538093712This. If you make aluminum wire thick enough to the point it has the same electrical resistance as copper it's still like 50% lighter.
>>538093712>>538093980Sounds like it's better than copper, why hadn't we already switched to aluminum?
Its aluminium you ignorant heathens>inb4 yank copeSo why not uranum and plutonum?
>>538094114It suffers from creeping where it changes size under heat and fucks up the connections on the ends of the wire over time. Guess copper has become expensive enough to the point where it's worth it to try and figure out proper connections for aluminum.
>>538092663that's good for Quebec which produces 60% of North American output.
>>538094114Because it's shit and causes house fire after 10 years.
>>538093761The insulation melts first
>>538093712>aluminium is cheaper, weights less, somewhat worse conductivityHalf of my subdivision is copper and the other half aluminum. The house fires that have occurred here since 1978 when my house was built were all on had the aluminum wiring. Expansion, contraction and oxidation make it inferior to copper.
>>538094114connections tend to rust overtimeBut with lifespan of modern cars and modern houses this is nonissueThe only reason to use cooper is if its relatively cheap which it isnt for a while now
>>538092663the cars are already made out of plastic, could they get much worse?
>>538094216Why isn't it platinium?
>>538094334you never mix aluminium and copper wires wtf
>>538094306Force à vous les Québécois !
>>538094460They make special connectors that are supposed to make it safe but yeah, shit's fucked.
wait until you retards realize power lines are aluminum and not steel cables yeah copper is the better material, but gold is the king shit hence why they use it for computersso yeah you loose some power in the transmission using aluminum but this is America and not some shithole 3rd world and we can just make more electricity because white people. more news at 11
>>538093712Except it oxidizes like crazy, breaks off in your wall and starts a fire. I'd imagine the automotive industry would have a way to prevent that from happening in cars, but I also know for a fact the chinese will figure out a way for it to not only catch fire but also emit toxic fumes when it does.
>>538092663copper is needed for high current applications - now with 800v plus archis its good enough...
>>538092663oh god oh fuck oh god oh fuck don’t do this do NOT do thisI remember when they did this for house wiring in, fuck was it the 1970’s? The corrosion is unbelievable, this shit is a time bomb for causing firesso much wiring had to be ripped out because of galvanic corrosion, embrittlement, just all kinds of nasty shit.No, it will not be better this time. The laws of chemistry do not change. Your shit will catch on fire because one day your car wiring will just start glowing like the coils in a toaster.
>>538097427cars have life of 20 years max - aluminium wires in walls became problem in walls after 50+ years of use - it shouldnt be problem for cars as they wil rust into oblivion faster anyway
COPPER CHADSRISE UP
>>538093761>Doesn't aluminum melt easily?see>>538093712>just need wires that are somewhat thicker.
>>538097427based chink bugsTCD starts at their home!
>>538092663nooooooooo
>>538097889>cars have life of 20 years maxTurn that proxy off, you will never be a real Pole.Houses don't tend to see a lot of atmospheric effects or vibration, we have no idea how aluminium wires would behave in a car because no one's ever been greedy enough to try.
>>538092663$30,000 car$100 worth of copper
>>538092663Pic rel: me telling the local meth addicts about all of the copper used in AI data centers
>>538097889except your house wiring isn’t being driven over North American roads in winter with salted slush being kicked up into the underbodythey had to recall tons of Japanese cars that were engineered to work perfectly for decades on Japanese roads but would get rust holes through the frames in a couple of years when driven in USA/Canada winter conditions.anyway plenty of houses had to be rewired in a lot less than 50 years, and automotive conditions are much more harsh than those experienced by residential wiring.
>>538092663As an electrician, aluminum was often used for low voltage lines, but copper is used for higher voltage. Like the power outlet that goes into your wall is wired with copper. I could see some of the displays and smaller lighting in cars being wired with aluminum but the main power supply (lithium ion battery) would likely still have copper wires for motor function. The copper wiring would then split off into a transformer that connects the main power to lower voltage aluminum wires for the small stuff.
>>538092663They already used in the past.Working but less efficiency and oxidizing easily.Gold contacts are the most flaweless.
>>538092663EV prices won't go down though lol. muh Capitalism
>>538098148well the wires are coated in plastic, it's the ends that are the problem due to the dielectric effect of different metals and aluminium corrodes badly. But sure over time what would the effect of high amperages be like? Maybe lower amperages would be ok, so maybe that is what would be changed really with copper still used for the high amps.
Higher resistance, lower flexibility. Poor reliability. Lots of new EV fires and malfunctions. There is a reason they do not use aluminum wiring in houses unless it's a cheap fixture. Now add in elements and vibration!
>>538098221bean counters again
>>538093712No, it's not. It is dangerous.
>>538092663The Hormussy being closed has caused copper prices skyrocket. No sulfur means no sulfuric acid to extract it.
>>538092663>using aluminum in something that ALREADY has a reputation for insane firesyou know what? go ahead. Time to cleanse this gay earth.
>>538094314Exactly! Reliability is horrible. Lots of EV fires coming up. Even more shitting disposable vehicles. Miles of aluminum wiring in a vehicle is a disaster.
>>538098478All EV fags will be cooked to death in their little mobile oven. I could see this happening six million times in the span of 4 years.
>>538098427Yeah, it's ok to use it in cars. When a car malfunctions and/or burns, nobody will get killed.
>>538098368Of course the prices won't go down. You're going to assume more risk and pay the same for an inferior product. Many such cases.
its because PCB's for data centers are eating up all the copper
>>538098238it would be quite a sight to see aluminum cables attached to the terminals of a 750 amp starter battery.It would be quite a sight to see from a safe distance through some goggles.
>>538098635Blasphemy from a German.It's poor engineering and it will cause death. What is an acceptable amount of death for the manufacturer?
>>538092663>https://www.timeanddate.com/countdown/to?iso=20260630T10&p0=263&msg=END+OF+BIRTHRIGHT+CITIZENSHIP&font=slabIt will reduce the cost of building a Ferrari by $7.50, increasing shareholder profit.
>>538094460There's no mixing. A subdivision is when a developer buys up a big lot and divides it into smaller properties to resell. He's saying some of the houses built on that had copper and some had aluminum.
>>538096922The new UHVDC lines in China is also made from aluminum composits.
>>538094255> over timeSounds like it's planned obsolescence
>The enshitification will continue until morale improves
>>538093712Ofc the gipsy knows the value of the wiring he rips out the walls.
>>538098705True, all of the boards for the graphics cards and cpus are on a sheet of copper. Then they need copper for heat pipes and heat sink fin stacks. Not to mention the millions of miles of copper wiring to power it all.
>>538093980do f1 and racing cars use aluminium wire?
>>538098230>houses had to be requiredNo they didn’t.The failure of aluminum house wiring happened years after its installation due to how aluminum reverberates under load. The connections at junctions had to be repaired. What’s more, we know about the issue now so it won’t cause future problems.
>>538098788>possibility of high voltage, high current dead short through aluminum wiring in the presence of oxidized iron components now that i think about it, this could be pretty cool
>>538098851You can use both copper and aluminum wires in the same circuit. They just have to be joined by a specially rated connector. The only thing to avoid is splicing them directly onto each other.
>>538099081>What’s more, we know about the issue now so it won’t cause future problems.famous last words
>>538098230there are multiple autos with aluminium bodywork (audi had lots of them) - so salt and generally weather shouldnt be a problem - it has to be kept in mind that aluminium corrode quickly when it comes into contact with copper and electrical current - its really easy to make something that will fall apart quickly as copper is very common in that application...
>>538093712Aluminum wires turn to powder over time with exposure to the elements. Its not used in residential wiring here because its a fire risk.
>>538092663Did they fail middle school science class? Aluminum isn’t conductive. You can’t replace copper with aluminum. That’s just not how current works.
>>538097427House fires only happen with overload of somethingAluminums was used in europe alot post ww2 and nothing caught fire with those wirings, however when stared adding dishwasher, mircowaves and toasters in kitches without changing wires that never had that power in mind, then you get firesso its not aluminium but overloadyou can overload copper wires as easy as aluminum
>>538092663>>538092807that was the whole plan, steal all the copper then sell it at high price you fool, then steal it again
>>538098401aluminium also cant be tinned or soldered, tin is already way more expensive than copper. so theyre gonna stop soldering also. how theyre gonna make PCBs without copper/solder?
>>538097957https://www.moneymetals.com/buy/copper/bars/1-oz-copper-barsHmmmmmm
>>538099117Pretty metal, just like your three last digits
>>538093761Pretty sure they stopped using aluminum wiring in houses because it kept causing fires.
>>538099497Why it's a never ending cycle of wealth.
>>538096922>gold is kingsilver is the ultimate electrical conductor, retard. gold isn’t even as efficient as copper. they use gold in computers because it won’t tarnish, not because of its superior electrical conductivity. retard
>>538099532maybe friction welded or simply mechanical joints, crimped for ends and then there is rivets. I suppose it isn't that they would get rid of all copper, brass etc it's getting rid of enough for their accountants to be happy. I suppose if they could do everything with fibre optics and carry the amps and voltage they could. EV's tho will still need the high amps wires made from copper till they get into t the lower amp parts.
>>538093712I work in the electrical supply industry. We have seen the transition from everything bigger than about 3/0 thhn jacket copper switch to xhhw jacket aluminum. Most smaller sizes of building wire like thhn 10 / 12 or MC / romex has remained copper. Its actually funny that they label the spools "ALUMINUM NOT COPPER DONT STEAL" and even funnier is that we put that on our copper spools to trick the methheads. The xhhw jacket typical of aluminum is more durable than the thhn jacket typical of copper. As retarded as this war is, sitting on a quarter million dollars of inventory in copper is p cool when that orange cuck retard starts sperging about tarriffs on imports. Music to my ears. Put another 5 points of gp on that bitch.
>>538098238The house service wiring and large subfeeders are almost always aluminum.A significant reason to use aluminum wiring in cars is recycling. The wire isn't all removed before shredding, so your wire material will be in the steel melt as a contaminant. Copper freely dissolves in molten iron and some of its effects are undesirable, like a tendency for the resulting steel to become brittle when hot (red shortness). Aluminum, however, is harmless and beneficial; it scavenges nitrogen and carbon monoxide, and reduces porosity.
>>538100070>The xhhw jacket typical of aluminum is more durable than the thhn jacket typical of copper.You can get large diameter copper with XHHW. At least in towns with lots of industrial customers. But with copper's greater stiffness that stuff is brutal to work with.
>>538093712yeah until you factor in oxidation, corrossion and then if a short occurs. The aluminum wired thing goes up in flames
>>538100898doesnt happen though, you are talking about some incidents from 100 years or some new shitfuckery where my buddy electrictian connected new copper wires on precxisting aluminum wires badlyits literally safe as copper, even conector galvanization is solvedno issue with aluminum at all
>>538093761It corrodes much more easily so electrical reliability will probably go down hill.
>>538092663Should we start hoarding copper?
I'm sure nothing will go wrong interfacing the aluminum wires to copper circuitry.
>>538094114increased fire risk. aluminum oxide will build up over time on the contacts. typically old aluminum wires get replaced with copper because it's safer even if it's more expensive.
>>538101232beverly hills supper club fire was 50 years ago. around 200 dead. aluminum wiring in the walls.
>>538092663Based. There's no practical reason to use copper wiring, other than it's easier for installers. >>538094334That's probably due to 1978 and not aluminum. When push connectors were allowed.
>>538104322>no practical reasonexcept it is tried and tested same as using brass in electrics as well and steel.
>>538099280the aluminum is probably painted and well coated. aluminum metal/oxide in contact with chlorides in salts corrode extremely quickly. pic somewhat related, CuCl in contact with aluminum foil. the lighter color on the foil is the metallic aluminum exposed after the native aluminum oxide was etched away by the HCl forming from CuCl in contact with water adsorbed on the aluminum foil surface. the copper color is metallic copper forming after reduction by physical contact with the reduced aluminum. the aluminum metal then oxidized into an aluminum chloride which is volatile and evaporates away. the elapsed time between CuCl contact and taking this picture was about a half hour
Aluminum wires get brittle very quickly when subjected to bending.All of those wires going from the main body of the car into doors, trunk lids, etc. could never be aluminum. They'd fail after a year.Same can be said about wires attached to anything that moves a little, like suspension, the engine, etc. except it may take longer because of less movement.
>>538093712>so you just need wires that are somewhat thicker.and more expensive as more neededcircle closes
>>538092663we won
>>538092663There was aluminum wiring in USSR in houses but it was ditched because of the fire hazard. I lived in a house with aluminum wiring and it the system was set to super low loads: if I turned on a stove while a kettle was on, the fuses would blow and had to be changed. Otherwise the wires would heat and set the place on fire.
>>538094114Because of all the house firesWe should be using gold for connections and wiring but it's too pretty and jews love pretty.It's their precious.Imagine thinking gold has any intrinsic value other than it's shiny. We're still apes stupid fucking apes.
>>538094460You can. It actually is okay You have to use a special deoxifying liquid and special connections They actually suggest it when you change fixtures. It's called pigtailing
>>538104850there are not that many house fires caused by copper fired and the connections. If the wiring is old, has rubber sheathing instead of modern PVC the nit's a risk because the rubber could have perished. Electrical fires are usually people overloading circuits and those circuits not having the correct sized breaker. Modern consumer boxes with RCD's etc mean there really is no excuse
>>538098436You can just say jews.
>>538092663Datacenters are ruining cars now too lol
>>538105033Again in English this time
>>538092663uh oh time to sell KGHM
>>538105341>copper fired>the nit'scopper wiresthen it's
>>538104488Tetraethyl lead is also a time tested anti knock additive.
>>538092663This has already been done in the 70s with housing and it was a total disaster and was banned in like less than decade due to the fire hazards.>Expands and contracts too much, loosening connections and resistance which creates heat which created more expansion and contraction which increased resistance which creates more heat which causes more expansion and contraction which creates more heat etc etc.>Fractures when being worked on, can't handle nearly as many bends and moving around as copper before microfracturing occurs which creates heat which created more expansion and contraction which increased resistance which creates more heat which causes more expansion and contraction which creates more heat etc etc.
>>538097889>cars have life of 20 years maxThat's you problem and a manufacturer's problem. I'd pay double or more for a vehicle guaranteed to make 500,000 miles. This is why Silveradoes and Tacomas have so much value on the used market.
>>538105708I suppose comparing high amps and voltage is not the same as a 12v circuit with low amps as well - if the amps are low say just for wiring looms for those circuits in cars then that would be fine. The connections in looms are plastic with the metal contacts. It's what is being replaced and what is kept.
>>538105959Don't accept aluminum wiring anon. We are always racing to the bottom in quality and not even getting price reductions because we aren't making hard lines in the sand. It's all rigged against us.
>>538094114In the 50's. There was a copper shortage after the war, like our house still has aluminum wiring installed from that time. It's really thick though and if I remember right, has some issues copper doesn't have electrically. My cousin is an electrician, he would know more about that. But aluminum wiring was used for awhile. You should see some of the fuses from that time. It's almost a miracle all houses didn't burn down in the 50's. Probably cause there was no browns to neglect checking the boxes
I like it. Ohh I know all about it but I had a few too many head injuries, sometimes I check to see if I am wearing a helmet "not kidding" that's what it feels like. I am an unhinged accelerationist. If that's what they want go for it, what's a few families here and there or a parking garage or a dealership or mechanics shops or a tow yard or impound yard or some really good places we could park these. Am comfy for now. Let it all burn. Fuck em all forever. Good. Just keep your mouths shut. Let it happen damn you
>chinese retarded, more news at 11I look forward to more electric fire deaths in china
>>538092663Oh sweet, now the wiring harness will fuck up even faster. Old cars gernerally had 20 years to problems to arise. New ones (2015+) are having the same issues already.
>>538105936Manufacturers don't care about a vehicle beyond 10 years, they are considered economic scrap. The average daily miles done even in the US is less than 50 miles. Yes that is an average and people will drive les maybe just a few miles and some will do much more. But if say 20k miles are done a year after 10 years it's 200k miles on the clock. No one is really touching that without either wanting it for peanuts or they know it is worth it and can be easily fixed. For people wanting those older cars then they won't be warring about manufacturers snitching to things that means vehicles are failing once they are not economically viable to be fixed.
>>538106409Do you know how catastrophic an ev fire is? It won't just be cars burning down, but homes as well. People will die, possessions lost, and the companies will have gobbled up ALL of the cost savings of using aluminum.
>>538106144Old truck don't give a fk. Fuck it. Party on Dave wtf is your problem. You motherfuckers. Say yes to competency crisis. Encourage it. Please
>>538106572Uhh yes I do. Now she. Loose pussy lips stink ships. What do you think we hire all these guys for. Now accelerate your breasts bitchezzzzzz
