PURPOSE:To provide a Cu alloy consisting of prescribed percentages of Ti, Ni, Zn and P and the balance Cu and having superior mechanical characteristics such as heat resistance, high resistance to tension, tensile strength at high temp., resistance to stress corrosion cracking and elasticity. CONSTITUTION:This Cu alloy consists of 0.1-1.5% Ti, 0.2-2.5% Ni, 0.05-2.0% Zn, 0.003-0.2% P and the balance Cu. The Cu alloy is proof against high temp. and shows superior oxidation resistance and high strength even after annealing at high temp. The Cu alloy has superior characteristics with respect to electric conductivity and very high heat resistance, so it can be widely used as a material for a heat exchanger, parts for the electric industry, parts which undergo heating to high temp. by brazing or other method, etc.
