Fabrication and Heat Treatment
Brass includes a broad range of copper-zinc alloys having a
variety of properties such as ductility, wear-resistance, color,
machinability, strength, hardness, antimicrobial, corrosion-resistance,
and electrical and thermal conductivity. UNS C69400 silicon red brass
alloy is one of the types of brass, which have hot forgeability, high
strength and good corrosion resistance.
