Title:
ZINC-BASED ALLOY SHOT
Document Type and Number:
WIPO Patent Application WO/2012/081276
Kind Code:
A1
Abstract:
[Problem] To provide a zinc-based alloy shot containing added Cu, the zinc-based alloy shot having a minimally discolored novel structure and readily affording a material of relatively high hardness; and a to provide method for manufacturing the same. [Solution] The zinc-based alloy shot contains a primary additive element Cu for the purpose of increasing Vickers hardness and the like; and a secondary additive element for the purpose of increasing Vickers hardness and inhibiting corrosion; and exhibits a Vickers hardness of 40-150 HV. The chemical composition is ordinarily 0.1-13.0% Cu and 0.0025-0.25 mass% Fe, with Zn constituting the balance; and satisfies the expression 1 ≤ Cu/Fe (mass ratio) ≤ 1000.
