Process for treating copper-aluminum-silicon alloys to improve fatigue strength

摘要

A process for improving the fatigue strength and fatigue life of a substantially single phase copper-aluminum-silicon alloy is described. The process comprises cold working the copper alloy from about 75% to about 98% and heating the alloy at a temperature of about 200 DEG C. to about 350 DEG C. for a time period of at least about 5 minutes.
