Abstract

PURPOSE: To obtain a high-strength Cu alloy having high electric conductivity by adding specified amounts of Ni and Ti to Cu and restricting the P content to a specified value or below.
CONSTITUTION: A Cu alloy having superior strength and electric conductivity is obtd. by adding 0.8W4.0wt% Ni and 0.2W4.0wt% Ti to Cu in 1W4 weight ratio of Ni/Ti and restricting the amount of P contained as an impurity to ≤0.05wt%. To the alloy may be added ≤2.0wt% in total of one or more among ≤2wt% each of Al, Zn and Sn. The Cu alloy is used as the material of a lead frame for a semiconductor integrated circuit.
