ASTM International’s committee on nonferrous metals and alloys is proposing two new standards. One is for a zinc-aluminum-copper alloy with improved strength while the other covers the requirements for die castings with thin walls.

The WK 63461 standard is for an alloy that seeks to improve the elevated temperature strength when compared to standard zinc die casting alloys while also improving castability. 

The WK 63462 standard will exist with an existing standard for high fluidity zinc alloy, (B989). It will provide composition requirements and consolidate the available physical and mechanical properties of these castings.
