ELECTROSLAG CRUCIBLE MELTING OF AGE-HARDENING COPPER-CHROMIUM ALLOY

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