What is the content of steel, iron, other elements etc in a car?
You generally won’t find much copper in a modern car! Generally it has been replaced by aluminium and plastics. There are reasons. Basically, iron has an extremely high carbon content. It is still mainly used in cars for the engine blocks, but again, has often been replaced by aluminium. Iron is rigid and hard. It can be cast in fairly intricate shapes. Even in aluminium block engines, you will find mostly iron liners for the cylinder bores. Pistons for engines are nearly always an aluminium alloy, for lightness, but the piston rings are generally iron for compression rings, but steel for oil rings. Steel is derived from iron, by removing most of the carbon and other elements found in iron. Depending on its use, it may have a controlled carbon content, and/ or other alloy additives. For instance, the car body metal needs to be easily formed, thus is a soft, low- carbon steel. When it is used as high- stress engine components like connecting rods, crankshafts etc., it will contain more
