A gold-chromium-cobalt alloy for sliding contacts

Abstract

A gold base alloy has been developed which can be precipitation hardened to make it suitable for use in sliding contacts. It is hard, strong and wear-resistant and has a low resistivity as well as a low contact resistance. The temperature coefficient of resistance can be varied and can be made low or zero at temperatures in the range 0 to 100°C. Its development is summarised and its properties compared with those of alloys generally used for sliding contacts.
