2oz 1340mm 99.9% Purity ED Copper Foil With International Standard
Description :
Copper has a high conductivity. Annealed copper is the international standard to which all other electrical conductors are compared. The main grade of copper used for electrical applications, such as building wire, motor windings, cables and busbars, is electrolytic-tough pitch (ETP) copper (CW004A or ASTM designation C100140). This copper has an electrical conductivity of at least 101% IACS (International Annealed Copper Standard). If high conductivity copper must be welded or brazed or used in a reducing atmosphere, then oxygen-free high conductivity copper (CW008A or ASTM designation C10100) may be used.Because of its ease of connection by soldering or clamping, copper is still the most common choice for most light-gauge wires.
