Copper is available in many forms including cathodes, ingots, bars, foils, sheet, granules, plates, powder, shot, turnings, wire, insulated wire, enameled wire, mesh, "evaporation slugs", and rods etc.

Copper is one of the most important metals. Copper is reddish with a bright metallic lustre. It is malleable, ductile, and a good conductor of heat and electricity (second only to silver in electrical conductivity). Its alloys, brass and bronze, are very important. Monel and gun metals also contain copper. The most important compounds are the oxide and the sulphate, (blue vitriol).
