    Revision of B989 - 14 Standard Specification for High Fluidity (HF) Zinc-Aluminum Alloy in Ingot Form for Thin Wall Die Castings

    (What is a Work Item?)

    Active Standard: B989 - 19a

    Developed by Subcommittee: B02.04 | Committee B02 | Contact Staff Manager



    castings; die castings; high fluidity; high fluidity alloy; pressure die castings; thin wall die casting; zinc; zinc-aluminum alloy; zinc metal;


    The Task group evaluated data related to HF thin wall castings and determined that the current composition specification in B989 for Ingots, should be for castings. Discussions assumed that there could be a loss of Al and Mg on melting ingot and during production of castings, therefore revisions being balloted are changes to the Aluminum and Magnesium ranges.
