Copper alloy for electrical or electronic equipment

Abstract

Abstract PURPOSE:To obtain a material for an electric or electronic apparatus with high strength, high ductility and superior softening resistance by adding specified percentages of Mg, Fe and P to Cu. CONSTITUTION:A Cu alloy consisting of, by weight, 0.03-0.3% Mg, 0.03-0.3% Fe, 0.1-0.3% P and the balance essentially Cu is prepared. Ag, Al, Sn, Zn, Co, rare earth elements, etc. may be added to the alloy by <0.5wt% in total, and residue of a deoxidizer such as B or Ca may be contained in the alloy by an amount exerting no influence on the electric conductivity. This Cu alloy has high strength (high tensile strength and hardness), high ductility (high elongation and bending values), sufficient softening resistance and superior suitability to plating.
