FIELD: metallurgy.
SUBSTANCE: proposed method comprises introducing the cathode of alloying elements from slightly soluble aluminium into molten aluminium by diluting it in potash cryolite-aluminous melt or a mix of potash and sodium cryolite-aluminous melt, or in sodium cryolite-aluminous melt at 700-960°C and anode current density of 0.2-1.5 A/cm2 and reducing alloying elements in molten aluminium on cathode. Metal allot or cermet, or ceramic material with the content of alloying elements of 2-97 wt %, are used as slightly anode. Stannous, nickel, iron, copper, zinc, chromium, cobalt and silicon are used as alloying elements.
EFFECT: ease of manufacture thanks to reduced temperature and labor content.
