Room Temperature Organization of Brass under Differen Zinc Contents

Ordinary brass is a copper-zinc binary alloy, and its zinc content varies widely, so its room temperature structure is also very different. According to the Cu-Zn binary state diagram, there are three types of brass room temperature: brass with a zinc content of less than 35%. The microstructure at room temperature consists of a single-phase α solid solution called α-brass; zinc-containing Brass in the range of 36% to 46%, the microstructure at room temperature consists of two phases (α + β), called (α + β) brass (two-phase brass); zinc content exceeds 46 From % to 50% of brass, the microstructure at room temperature consists only of the beta phase, called beta brass.
