Zn alloy and Zn alloy die-cast product null for die-cast

摘要

PROBLEM TO BE SOLVED: To provide a Zn alloy for die-casting which enables cavity defects occurring therein to be suppressed and the thickness thereof to be reduced as a result, and to provide a die-cast product.;SOLUTION: The Zn alloy for die-casting comprises, by weight, 3 to 5% Al, 0.03 to 0.06% Mg, 0.5 to 5% Cu, further 0.01 to 1.0% of misch metal composed of one or more rare earth elements, and the balance Zn with inevitable impurities. In the die-cast product obtained by using this alloy, cavity defects can be remarkably decreased.;COPYRIGHT: (C)2007,JPO&INPIT
