EZAC™ - A Novel High Strength, Creep Resistant, Hot Chamber Zinc Die Casting Alloy 2011-01-1084
Progress in recent alloy development work has resulted in the commercialization of a high strength, creep resistant, hot chamber zinc based die casting alloy. The work was based upon earlier research conducted under the sponsorship of the Department of Energy Cast Materials Consortium (CMC). Refinement of alloy chemistry produced significant improvements in tensile strength, hardness and creep performance. Because the composition of this new alloy is near that of the Aluminum/Copper/Zinc ternary eutectic, the low melting temperature enables the alloy to be cast in a hot chamber die casting machine without excessive wear of shot end components typically experienced with other high-copper zinc die casting alloys contents such as ACuZinc 5.
