RS-300 (AlSi10Mg)

This is the basic aluminum alloy with good casting properties and performance during powder bed fusion. Alloy offers good strength and ductility after annealing. Properties are equal or superior to traditional casting Al-Si alloys. Printed parts can be treated in a similar manner as for casted parts.
