Zn alloy and the production manner for die-cast, Al mother alloy null for die-cast alloy

摘要

I provide a method of manufacturing a die casting Zn alloy with a rare earth element is uniformly dispersed without segregation. Al: 3~5mass%, Mg: 0.03~0.06mass%, rare earth elements of one or more: and containing 0.01~1.0mass%, the balance being unavoidable impurities and Zn, I is characterized in that the grain size is 5~10μm. A content of less than 10mass% exceeding 3mass% rare earth elements of one or more, by adding Al master alloy balance being inevitable impurities and Al, Al: 3~5mass%, Mg: 0.03~ it is prepared by containing 0.01~1.0mass%, then the melted Zn alloy balance being unavoidable impurities and Zn, allowed to solidify: 0.06mass%, rare earth element or two or more species.
