CZ122

CZ122

CZ122 serves as the standard material for hot working operations. The average lead content contributes to favorable machinability of drop-forged components. Additionally, owing to its composition, the alloy is well-suited for fabricating intricate profiles and producing complex shapes through drawing processes.
