WebApr 13, 2024 · Alpha Brass (CuZn) Alpha brasses are single-phase alloys with a composition of 55-65% copper and 35-45% zinc. They exhibit a face-centered cubic (FCC) crystal structure. Technical Specifications. Alpha brasses are known for their excellent cold workability, which is a result of their ductility. WebThe microstructure of these brasses is a face centred cubic crystal structure which can be cold worked. Alpha brasses are used for the manufacture of items such as pins, bolts, screws, cold headed components, heat exchangers, fasteners, rivets and other machined parts. Beta brass. Beta brass contains more zinc than alpha brass; over 45%.
