Beschreibung
Zusammenfassung:	The invention relates to the field of metallurgy, more particularly to heat-resistant aluminium alloys for use in additive technologies. The alloy comprises nickel, manganese, iron, zirconium, cerium, at least one element from a group consisting of: copper, magnesium and zinc, and at least one element from a group consisting of: silicon and calcium, wherein Ni > Mn + Fe, one or more eutectic phases such as Al3Ni, Al16Mn3Ni, Al9FeNi having thermal stability, and dispersoids such as Al3Zr, all of which provides for the ultimate strength of an article of at least 370 MPa. The technical result consists in providing an aluminium material to be used in the powder form, characterized by good processability during printing and enhanced strength characteristics at room temperature after printing and without a significant loss of strength after annealing.
