FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, namely to heat-resistant aluminum alloys with high structure stability for use in additive technologies in powder form. Alloy contains nickel, manganese, iron, zirconium, cerium, at least one element from group: copper, magnesium, zinc, as well as at least one element from the group: silicon, calcium, wherein Ni>Mn+Fe, one or more eutectic phases such as Al3Ni, Al16Mn3Ni, Al9FeNi, having thermal stability, as well as dispersoids of type Al3Zr, which provides ultimate strength of article in state after printing or annealing of not lower than 370 MPa.
EFFECT: development of new heat-resistant aluminum material for its use in the form of powder having good processability during printing, as well as high strength properties at room temperature after printing, without strong reduction of strength after annealing.
