Abstract

Copper alloys, particularly for use as electrical conductors, e.g. commutator segments, contain 0.01-0.15% by weight of zirconium which is at least equal in purity to that produced by the commercial Kroll process and the balance copper, and the alloys are solution annealed at a temperature in the range 1300 DEG F.-1900 DEG F., quenched and then subjected to cold-working. The time of solution annealing is preferably 5-60 minutes and the cold-working may be such as to produce a reduction in cross-sectional area of about 50%. Before or after cold-working the alloy may be aged at a temperature in the range 450 DEG F.-950 DEG F., e.g. for 60-120 minutes.
