The copper basic alloy for metal mold casting the ingot product null Cu which uses

摘要

PROBLEM TO BE SOLVED: To provide a copper-based alloy which can be widely applied to all fields requiring machinability, mechanical properties and corrosion resistance by improving erosion resistance, corrosion resistance, cast crack resistance and further impact resistance at a high temperature, and has superior cost efficiency, and to provide an ingot and a product using the alloy.;SOLUTION: The copper-based alloy has a composition consisting of 61.0-61.8 wt.% Cu and 0.8-2.4 wt.% Sn; and has improved dezincification resistance, erosion resistance, corrosion resistance and cast crack resistance.;COPYRIGHT: (C)2006,JPO&NCIPI
