Common Brass

63/37 Yellow Brass

A copper-zinc alloy with an alpha phase structure possibly also containing a small amount of beta phase, depending upon fabrication history. Service environment must be considered to predict corrosion behaviour. The alloy can be hot or cold worked and its ductility, although lower than that of Cu Zn28, Cu Zn30 and Cu Zn33, permits quite severe deformation, including cold heading of rod and wire. Cu Zn37 is mainly used for simple cold presswork not involving deep-drawing.
