ALUMINIUM-BASED CONDUCTOR MATERIAL AND ARTICLE MADE FROM IT Russian patent published in 2024 - IPC C22C21/00 H01B1/02 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, namely to materials for electrical purposes based on aluminium, in particular for the manufacture of conductors of electrical cables, wires and cords of a wide range of types, high-voltage power lines and having the required complex of heat resistance, mechanical and electrical characteristics, including material capable of operating at temperature up to 150 °C without significant loss of strength properties. Conductor material contains, wt.%: iron 0.15–0.5, silicon 0.04–0.12, zirconium 0.02–0.06, scandium up to 0.05, aluminium and unavoidable impurities – the rest. Structure of the conductive material is formed by an aluminium solution, eutectic particles containing iron and silicon, optionally secondary precipitates of type L1₂, and the specific electrical resistance of the conductor material does not exceed 0.0286 mcOhm⋅m.

EFFECT: material is characterized by high mechanical properties and specified level of specific electrical resistance and heat resistance.
