ALUMINUM-CALCIUM ALLOY Russian patent published in 2023 - IPC C22C21/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to the field of metallurgy of materials based on secondary aluminum and can be used for the manufacture of both shaped castings and deformed semi-finished products intended for the production of critical parts operating in a corrosive environment at temperatures up to 300-350°C. The aluminum-based alloy contains, wt.%: calcium 2.0-3.0, manganese 1.2-2.0, iron 0.2-0.4, silicon 0.1-0.3, copper 0.05-0.3, zinc 0.1–1.0, aluminum the rest, and the total content of calcium, manganese and iron should be in the range from 4.6 to 6.0 wt.%.

EFFECT: invention is aimed at creating an economically doped alloy based on aluminum with the possibility of obtaining both shaped castings of complex shape and deformed semi-finished products and having high mechanical properties without the use of heat treatment.
