FIELD: metallurgy.
SUBSTANCE: procedure involves the use of anodes containing two-phase metallic copper-base and iron-base alloys that also include small amounts of nickel, consisting of an iron-rich reactive phase and a copper-rich solid inert phase and containing from 30 to 77 wt .% copper, from 23 to 65 wt % iron and 15 wt % nickel, in which the content of the reactive phase in Cu-Fe-Ni two-phase alloy is 24-83%, and the inert phase is in the space between the dendrites of the reactive phase.
EFFECT: possibility to achieve a significant reduction in the corrosion rate of anodes in alumina-containing fluoride melts under conditions of anodic polarisation, and to obtain aluminium with a low content of metals - components of the anode is ensured.
