THERMO-ANTICORROSIVE ALUMINIUM ALLOY Russian patent published in 2017 - IPC C22C21/00 

FIELD: metallurgical engineering.

SUBSTANCE: invention relates to the field of metallurgy of conductive aluminium alloys and can be used for the manufacture of electrical products, in particular the wires of high-voltage power lines and cables of submersible oil pumps operating at temperatures up to 230 °C, when a combination of high strength at elevated temperatures, high corrosion resistance, increased electrical conductivity, reduced creep and reduced mass is required. Aluminium alloy contains, wt %: zirconium 0.2-0.32; iron 0.15-0.42; silicon 0.02-0.1; titanium, chromium, vanadium, manganese in the amount of 0.01-0.04; magnesium, copper, zinc in the amount of 0.01-0.07; nickel 0.005-0.1; boron 0.001-0.01; aluminium - the rest. The technical result of the invention is to increase the heat resistance and corrosion resistance of the aluminium alloy.

EFFECT: alloys high-tech and has improved performance characteristics.
