non-ferrous metallurgy; production of copper-based alloys containing readily oxidable components; smelting casting alloys. SUBSTANCE: flux for melting said alloys contains sodium and boron oxides and cryolite at the following ratio of components, mas.%: sodium oxide, 28-20; cryolite, 3-5; boron oxide, the balance. EFFECT: enhanced deoxidizing ability of flux at retained protective properties; reduced viscosity of flux. 2 tbl
