Copper alloys with 1.5 to 2% Beryllium additions that have the highest strengths of all Copper Alloys by both heat treatment (solution treatment and age hardening) and cold working.
A brass with very high Zinc content. It will have a predominantly beta phase microstructure, be brittle and used only as a brazing filler alloy.
A phase in the microstructure of brasses that contain more than about 36% Zinc. Beta phase adversely affects the cold formability of brasses and hot working processes, such as hot stamping, are preferred.
Copper of about 98% purity obtained by 'converting' copper matte.
Any alloy of Copper and Zinc.
