Electroslag crucible melting of age hardening copper-chromium alloy

Abstract

The electroslag crucible melting process, developed on the well established principles of electroslag refining, has been used to cast age hardening Cu-0.5Cr alloys using copper scrap. Initial trials have demonstrated the viability of electroslag crucible melting for producing cast alloys with low impurity content and superior tensile properties. The castings produced by electroslag crucible melting are of high quality in terms of surface finish and casting defects. The cast alloy could be successfully dt awn into wire of diameter 3 mm.
