Brasses - Official Site of Copper Development

2018-8-1  Brasses are copper zinc alloys. In general, they have good strength and corrosion resistance, although their structure and properties are a function of zinc content. Alloys containing up to approximately 35% zinc are single phase alloys, consisting of a solid solution of zinc and alpha copper.

Brass - Wikipedia

2018-10-10  Brass has higher malleability than bronze or zinc. The relatively low melting point of brass (900 to 940 °C, 1,650 to 1,720 °F, depending on composition) and its flow characteristics make it a relatively easy material to cast. By varying the proportions of copper and zinc, the properties of the brass can be changed, allowing hard and soft brasses.

Learn About the Different Brass Types - The Balance

2018-6-18  Alpha brasses contain less than 37% zinc melted into copper and are named for their formation of a homogenous (alpha) crystal structure. The alpha crystal structure occurs as zinc dissolves into copper forming a solid solution of uniform composition.Such brasses are softer and more ductile than their counterparts and, therefore, more easily cold worked, welded, rolled, drawn, bent or brazed.
