1. An aluminum alloy comprising:
nickel with a proportion from 2.1 wt % to 5.5 wt %;
balance aluminum, and unavoidable impurities with a total of less than 0.5 wt %; and
scandium with a proportion from 0.1 wt % to 3.0 wt %;
optionally at least one first additional alloy element that is suitable to complement or to substitute scandium, wherein an individual proportion of an individual first additional alloy element does not exceed 2.0 wt % and a total proportion of the at least one first additional alloy element does not exceed 3.0 wt %;
optionally at least one second additional alloy element that is selected from a group consisting of vanadium, niobium, chromium, molybdenum, silicon, iron, and cobalt, wherein an individual proportion of an individual second additional alloy element does not exceed 2.0 wt %, and a total proportion of the at least one second additional alloy elements does not exceed 3.0 wt %;
optionally at least one third additional alloy element that is selected from a group consisting of magnesium, manganese, and calcium, wherein an individual proportion of an individual third additional alloy element does not exceed 2.0 wt % and a total proportion of the third additional alloy elements does not exceed 3.0 wt %,
wherein the alloy is free of at least one of zirconium or calcium.
