Abstract

PURPOSE: To provide a Cu alloy provided with high strength and high electric conductivity and suitable for use as the material of a lead frame for a semiconductor by adding specified amounts of Sn, P, Ni and Zn to Cu.
CONSTITUTION: This Cu alloy consists of, by weight, 1.7W2.5% Sn, 0.01W0.15% P, 0.1W0.6% Ni, 0.05W1% Zn and the balance Cu with inevitable impurities. In the composition, the lower limit of the Sn content is the irreducible minimu of Sn required in consideration of the effect of added Ni, and the upper limit is defined in points of cost and electric conductivity. Ni in said range refines the grains of a Cu-Sn alloy contg. said amount of Sn and exerts little influence on the electric conductivity. Zn is added by said relatively large amount so as to increase the deoxidizing effect of P and to improve the plastic workability. The Cu alloy is relatively inexpensive and has characteristics comparable to those of conventional phosphor bronze.
