Addition of beryllium, up to about 2 wt%, produces dramatic effects in copper, nickel, aluminum, magnesium, gold, zinc, and other base metal alloys. This Article provides information on the chemical composition, microstructure, heat treatment, fabrication characteristics, production steps and physical metallurgy of beryllium-copper, beryllium-nickel, and beryllium-aluminum alloy, and tabulates their mechanical, electrical and physical properties, and temper designations. It describes the important features of this alloy group, including information on safe handling. Additionally, the Article presents examples of the beneficial properties of beryllium-copper alloys and quantifies some of the major reasons for their selection for particular applications.
