BERYLLIUM-FREE HIGH-STRENGTH COPPER ALLOYS

摘要

A beryllium-free high-strength copper alloy includes, about 10-30 vol % of L1 2- (Ni,Cu)3(Al,Sn), and substantially excludes cellular discontinuous precipitation around grain boundaries. The alloy may include at least one component selected from the group consisting of: Ag, Cr, Mn, Nb, Ti, and V, and the balance Cu.
