<P>PROBLEM TO BE SOLVED: To provide a zinc-base alloy shot which is used for surface processing to remove burr from or grind and clean an aluminum die casting product or magnesium die casting product by shot blast, has superior cost performance, does not deteriorate erosion resistance and is in accordance with surface hardness of a product to be processed. <P>SOLUTION: The zinc-base alloy shot of three component system contains 1.800 to 6.000 mass% Cu and 0.0010 to 0.5000 mass% Fe as additional elements, where Vickers hardness is 80 to 110 HV, and purity of Cu to be an additional element is ≥99.9 mass%. The zinc-base alloy shot is used for shot blast of aluminum alloy die castings or magnesium alloy die castings. <P>COPYRIGHT: (C)2013,JPO&INPIT |
