FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, particularly to a method of producing condenser aluminium foil for manufacture of condensers with a high specific charge. The method of producing a condenser aluminium foil includes melting a charge formed by adding to high-purity aluminium with an aluminium content of 99.99% wt. an Al - 1% wt. Er master alloy at a ratio by weight between 1:1000 and 1:10, obtaining a cylindrical ingot with erbium concentration between 0.001 and 0.1% wt., refining and homogenising the ingot, hot and cold rolling resulting in foil with a thickness of 20 to 30 mcm.
EFFECT: invention is intended to increase specific capacity of foil while maintaining the level of mechanical characteristics.
