FIELD: metallurgy.
SUBSTANCE: aluminium alloy is prepared, reheated over alloy liquidus curve temperature. Copper is added into the aluminium melt in the form of a wire, at the same time electric current is sent between the wire and the melt. Wire melting is carried out without formation of an arc at the ratio of current density to speed of wire feed equal to 0.3-1.0·1010 A·s/m.
EFFECT: invention makes it possible to reduce losses of alloying components and to reduce energy intensity of production of aluminium-copper alloys.
