Abstract

Berylco 165 is a lower cost version of the standard 1.9 percent beryllium copper alloy. It offers good formability in the unhardened condition with high final properties following precipitation hardening. It is also available in the mill hardened condition which, without heat treatment by the fabricator, reaches strengths and hardnesses appreciably higher than bronze. Through good formability, it offers cost-saving opportunities by eliminating hardening. It combines good ductility with high strength and hardness, good electrical and thermal conductivity, and excellent resistance to wear and fatigue. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as heat treating, machining, and joining. Filing Code: Cu-20. Producer or source: Beryllium Corporation. Originally published November 1954, revised April 1963.
