Zinc Alloy Ingots for High Pressure Die Casting
|Publication Date:||1 June 2017|
This material specification covers commercial zinc alloys in ingot form for remelting for the manufacturing of high pressure die castings used in automotive applications and other allied industries. Zinc alloy ingots are specified by the chemical composition.
Material Description. These zinc alloy ingots are produced for use in high pressure die casting. Each zinc ingot grade has a composition that aligns with, but is tighter than, the respective die cast grade. The various grades of pressure die cast zinc alloys can be referenced in GMW worldwide specification GMW3341.
Material Identification. This specification covers the GMW3344 ingot grades listed below in Table 1 and the commercial alloy that each ingot will ultimately make. Appendix Table A1 provides a relationship between some of the national and international specifications and these GMW3344 alloy grades.
Symbols. Not applicable.
Applicability. Zinc alloy ingots are used as the base melting stock to cast zinc alloy parts for automotive usage. Various compositions are needed to meet the strength requirements of the different high pressure die casting grades.
