Aluminum alloy for additive technologies

A method for producing an aluminum powder from an aluminum-based alloy, the method comprising:

• (a) adding a scandium and a zirconium batch-wise as master alloys to an aluminum melt at a temperature from 850-950° C. to avoid super cooling of the aluminum melt to a temperature below 750° C.;
• (b) adding calcium as a master alloy after dissolution of scandium;
• (c) adding magnesium;
• and
• (d) atomizing the aluminum melt using a nitrogen-oxygen or argon-oxygen mixture with an oxygen content of 0.2-1.0 vol. % to obtain the aluminum powder while maintaining the following ratio of the aluminum melt composition components before atomization (wt. %):
• magnesium 4.0-6.5;
• zirconium 0.5-1.0;
• scandium 0.2-0.6;
• calcium 0.005-0.15;
• and
• aluminum and inevitable impurities being remainder components.
