FIELD: metallurgy.
SUBSTANCE: invention relates to composition and technology of producing blanks and parts from aluminium-based materials, including using selective laser fusion techniques. Aluminium-based alloy contains, wt. %: Si 10.0–14.0; Mg 0.3–1.0; Cu 0.3–1.0; Mn 0.3–1.0; Ti 0.12–0.30; Fe 0.1–0.50; Al is rest. Powder obtained from said aluminium alloy by melt spraying has average particle size of 20 to 150 mcm and is intended for making articles by additive technology.
EFFECT: invention is aimed at improving mechanical properties of alloy and obtaining articles from powder by additive technology with high strength.
