Abstract
Improved method for melting copper base alloys containing from 2 to 12% aluminum including the steps of covering a molten mass of said copper base alloy with an essentially continuous flux layer of a molten salt consisting essentially of from 10 to 90% by weight of potassium chloride, from 10 to 90% by weight of sodium chloride and less than 5% by weight of other materials, said salt having a melting point of from 660 to 800.degree. C, and adding additional amounts of said alloy through said flux layer.
