FIELD: non-ferrous metallurgy. SUBSTANCE: process is related to making of copper-based alloys from secondary basic materials. Process of making of copper-based alloys is conducted under layer of flux having following composition, mas. %: NaCl, 20.0-25.0; CaCaF2, 25.0-30.0; Na2CO3, 45.0-50.0. In this case proposed proportions of components of flux provide for reduced content of impurity in alloy to limits specified by State Standard. Alloy can also be made under flux with addition of carbon-carrying waste of petrochemical industry as well as at temperature of boiling of alloy. EFFECT: increased degree of refining of alloy from metal impurities contained in it. 2 cl, 2 tbl
