Abstract

See full text

One aspect of this copper alloy for an electronic device is composed of a binary alloy of Cu and Mg which includes Mg at a content of 3.3 to 6.9 atomic %, with a remainder being Cu and inevitable impurities, and a conductivity σ (% IACS) is within the following range when the content of Mg is given as A atomic %, σ≤{1.7241/(−0.0347×A2+0.6569×A+1.7)}×100. Another aspect of this copper alloy is composed of a ternary alloy of Cu, Mg, and Zn which includes Mg at a content of 3.3 to 6.9 atomic % and Zn at a content of 0.1 to 10 atomic %, with a remainder being Cu and inevitable impurities, and a conductivity σ (% IACS) is within the following range when the content of Mg is given as A atomic % and the content of Zn is given as B atomic %, σ≤{1.7241/(X+Y+1.7)}×100, X=−0.0347×A2+0.6569×A and Y=−0.0041×B2+0.2503×B.
