ASTM B989 Specification for High Fluidity Zinc-Aluminum Alloy in Ingot Form for Thin Wall Die Castings

15 September 2014

Thinner cell phone casings and business card holders are just two of the applications for a new high fluidity zinc die casting alloy. This casting is covered by a new ASTM standard, ASTM B989, “Specification for High Fluidity (HF) Zinc-Aluminum Alloy in Ingot Form for Thin Wall Die Castings.”

The HF alloy was developed through a project coordinated by the Cast Metals Coalition, an industry consortium that includes the North American Die Casting Association and the International Zinc Association. Because the composition of this alloy is unique, a new standard for it was needed.
