ASTM Proposes New Standards for Zinc Diecasting

Posted by Hill and Griffith Company on Jun 20, 2018 2:44:58 PM

One proposal would improve high-temp Zn-Al-Cu alloy; another would define composition for high-fluidity alloy

ASTM International’s Committee on Nonferrous Metals and Alloys proposed two new standards: one for a zinc-aluminum-copper alloy with improved strength; another for determining requirements for thin-wall diecastings.

Zinc alloys are used to design diecastings because of their hardness, self-lubricating properties, dimensional stability, and high modulus make them suitable for working mechanical parts, like gears and pinions. Zinc also offers thermal and electrical conductivity and precise casting tolerances, which are useful for heat sinks, electrical components and applications requiring electromagnetic shielding.
