【Abstract】 In this paper, metallographic structures of the cast ingot of Cu-9Ni-6Sn alloy prepared by vacuum molten-cast, going through hot and cold working under pressure afterwards, and undergoing heat treatments are investigated, and the regularity of variations of the structures are studied as well. The tensile characteristics, conductivity and corrosion resistance of the strip alloy after deformation by 99％ during cold rolling and appropriate aging have been measured. The results show that the strip alloy after especially big cold rolling deformation and aging possesses rather high strength and elasticity, and has moderate conductivity and good corrosion resistance.更多还原
