Title:
ALLOY HAVING LOW AGING CHARACTERISTICS
Document Type and Number:
Japanese Patent JP01147035
Kind Code:
A
Abstract:
PURPOSE: To manufacture the title alloy useful as the material of a mold for molding of plastics by adding a specific amount of Sr to a zinc-based alloy contg. specific ratios of Al, Cu and Mg.
CONSTITUTION: 50W200ppm Sr, by weight, is added to the zinc-based alloy consisting of 9W15% Al, 7W12% Cu, 0.01W0.1% Mg and the balance Zn consisting substantially of Zn with inevitable impurities. By this method, the alloy for a mold having excellent mechanical strength, having small dimensional and physical change by aging and easily executable of casting and working is obtd.
