POWDER MATERIAL WITH HIGH THERMAL CONDUCTIVITY Russian patent published in 2021 - IPC C22C21/02 

FIELD: metallurgy.

SUBSTANCE: invention relates to the field of metallurgy, in particular to powder materials based on aluminum alloys used for the manufacture of parts by methods for additive technologies, including the method for selective laser fusion. Powdered aluminum material for the manufacture of parts using additive technologies contains, wt.%: silicon 2.00 – 5.00, iron 0.10 – 0.50, magnesium 0.10 – 0.80, zirconium 0.10 – 0.40, copper no more than 0.02, manganese no more than 0.02, titanium no more than 0.02, aluminum and inevitable impurities – the rest, with a ratio of silicon, iron and magnesium content corresponding to the condition Si ≥ Mg*6,5+Fe*5.

EFFECT: invention improves the strength and thermal conductivity characteristics of an aluminum alloy intended for the manufacture of parts using additive technologies.
