A high strength, high conductivity copper base alloy consisting essentially of magnesium from 0.04 to 0.20%, phosphorus from 0.04 to 0.20%, a transition element selected from the group consisting of iron, cobalt, nickel and mixtures thereof in a total amount of from 0.04 to 0.20% and the balance essentially copper, wherein the microstructure is characterized by the presence of a substantially uniform dispersion of fine phosphide particles.
A method for obtaining high conductivity, high strength copper base alloys which comprises:
- providing a copper base alloy consisting essentially of magnesium from 0.04 to 0.20%, phosphorus from 0.04 to 0.20%, a transition element selected from the group consisting of iron, cobalt, nickel and mixtures thereof in a total amount of from 0.04 to 0.20%;
- heat treating said alloy for from 10 seconds to 24 hours at a temperature of from 250.degree. to 750.degree. C.;
- cold rolling said alloy;
- and finally heat treating said alloy for from 30 minutes to 24 hours at a temperature of from 250.degree. to 600.degree. C.
