Copper & Copper Alloys

Copper and its alloys are used in abundance because of their excellent thermal and electrical conductivities along with the ability to resist corrosion. These metals can be strong and easy to fabricate. They are commonly non-magnetic and vary in color for decorative uses. Copper and copper alloys are used for electrical contacts, pipes, valves, fittings and many other components.
