The car engine radiator.
Most of the wiring is copper, not much else.
Copper is a good conductor of electricity and is cheap. Wires for wiper motors, lights and power seat motors etc. are all made of copper.
The radiator is made of copper because copper transfers heat very well.
In a smelter. Heat drives off the parts of the ore that are not copper.
most car radiators are copper or aluminum and plastic.
car radiators used to be made of copper, copper doesnt rust. most radiators are now made from aluminum.aluminum also does no rust
In the past (quite a long time ago!) most car manufacturers actually made all the parts that went into the car, so they bought metal, plastic, wood, etc, and then made parts out of these materials, then made a car with the parts they had made. These days most car companies buy parts made by other companies, and then "assemble" the parts into a car. So they no longer "manufacture" a car, they "assemble" it.
Copper surrounded by a plastic insulator.
Nearly All American car parts are made in China, especially Ford.
