Copper and Its Alloys

Copper and its alloys

Copper is an element and a mineral called native copper.
• Copper is an industrial metal and widely used in unalloyed and alloyed conditions. (second ranked from steel and aluminium).
• Used mostly in building constructions and as electronic products.
Properties:
• High electrical conductivity.
• High thermal conductivity.
• High corrosion resistance.
• Good ductility and malleability.
• Reasonable tensile strength.
Application of copper in automotives
Copper: working in automotive applications.
Increasing use of electronic parts in cars raise the amount of copper used per vehicle.
