Brass Square Bar (C36800 C37000 C23000 C24000 C26000 C26800 C27000 C28000)
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. These brasses have good strength and ductility, and are easily cold worked. The strength and ductility of these alloys increases with increasing zinc content. The alpha alloys can be differentiated by a gradual change in color, from golden yellow to red, as the zinc content is increased up to 35%. Gilding 95%, Commercial Bronze, Jewelry Bronze, Red Brass and Cartridge Brass are in this category of brasses.
Brasses frequently contain lead in order to improve machinability. The microstructure of the leaded brasses is similar to that of the unleaded brasses with the addition of almost pure lead particles found in the grain boundaries and inter-dendritic spacings. The lead is observed in the microstructure as discrete, globular particles because it is practically insoluble in solid copper. The number and size of the lead particles increases with increasing lead content.
