Abstract
This specification covers commercial zinc and zinc-aluminum alloys in ingot form for remelting for the manufacture of pressure die castings, foundry castings and continuous cast bar stock. Seven alloy compositions are specified, which includes Z33521, Z33522, Z35530, Z35540, for zinc alloys and Z35635, Z35630, Z35840, for zinc-aluminum alloys. The material shall be of uniform quality and reasonably free from dross, adhering foreign matter, and surafce oxide. The determination of chemical composition shall be made in accordance with suitable analytical methods.
