Brass (MS58, MS63, Copper-Zinc Alloys)

Brass has good corrosion resistance properties and in general is easy to machine.Compared to steel and aluminium alloys, brass cannot be hardened by heat treatment. However, one can control the strength by choosing a suitable alloy or by mechanical working (e.g. rolling, forging or cold drawing).
