PURPOSE:To obtain an inexpensive white Cu alloy having fine appearance, high strength, superior corrosion resistance and press formability by specifying a composition consisting of Zn, Ni, Mn, Sn and Cu. CONSTITUTION:This white Cu alloy consists of, by weight, 20-40% Zn, 2-10% Ni, 1-10% Mn, 0.01-3% Sn and the balance Cu with inevitable impurities or further contains 0.01-3% one or more among Te, Cr, Co, Zr, V, Be, Cd, As and P as secondary components. The alloy has high Vickers hardness and satisfactory workability. It is inexpensive and suitable for use as a material for an automobile key and drawn products such as dinnerware.
