DEFORMABLE ALUMINIUM-BASED ALLOY Russian patent published in 2023 - IPC C22C21/00 

FIELD: metallurgy.

SUBSTANCE: invention is related to deformable aluminium-based alloys intended for use in form of deformed semi-finished products, mainly in form of extruded rods, as a structural material for conductive and heat-conducting structural elements, and also as a workpiece for production of electrical wires, welding wires and wires for additive manufacturing in aerospace, shipbuilding, cryogenic engineering and other industries. Wrought alloy based on aluminium contains, in % by weight: scandium 0.15-0.28, zirconium 0.05-0.13, iron 0.07-0.12, hafnium 0.02-0.05, unavoidable impurities, including magnesium (not more than 0.02), manganese (not more than 0.02), silicon (not more than 0.05), copper (not more than 0.02), zinc (not more than 0.04), titanium (not more than 0.02), chromium (not more than 0.02) with their total content not more than 0.5, the rest is aluminium, provided that the ratio between the content of scandium and the total content of zirconium and hafnium is from 1.5 to 2.5.

EFFECT: increase of the strength of the material.
