Abstract

PURPOSE:To mass-produce a copper alloy having excellent hot workability by limiting the elements to be added and the addition ratio of the Cu-Ni-Si alloy as well as the impurities and hot rolling said alloy at the prescribed temp. CONSTITUTION:The chemical component value of the Cu-Ni-Si alloy is regulated in such a manner that it contains, by weight, 2.0-4.0% Ni, 0.5-1.0% Si, 0.01-1.0% Mn, 0.05-1.0% Zn, 0.001-0.01% Mg and <=0.003% S and contains 0.001-0.01% total of one or more kinds among 0.001-0.01% B, 0.001-0.01% Cr, 0.001-0.01% Ti and 0.001-0.01% Zr; as the impurities, <=0.002% Pb, <=0.001% Bi, <=0.001% Sb, <=0.001% As, <=0.0005% Te and <=0.0005% Se are furthermore regulated and the balance is formed with Cu. Said alloy is then hot rolled at 700-900 deg.C. By this method, the copper alloy having no generation of cracks during the hot rolling can be obtd.
