    摘要: A high strength copper alloy of excellent bending processability containing Ni: 5-20 wt %, Sn: 0.5-3 wt %, Al: 0.5-5 wt %, Mg: 0.001-0.05 wt %, Cr: 0.001-0.1 wt %, Zn: 0.05-5 wt %, the balance of Cu and inevitable impurities, and having a tensile strength of from 80 to 120 kgf/mm.sup.2. Up to 0.2 wt % of one or more of Fe,Mn,Ti,Zr,P,In,Ta and Co can be added without a deleterious effect. The alloy is non-toxic and economical, as well as shows tensile strength and elongation at least comparable with beryllium-copper alloy and has excellent solderability and solder-resistant and heat resistant peelability. The alloy can be used suitably as materials for electric terminals, connectors, etc.
