Scalmalloy® (AlMgSc)

Alloys
FunctionalStrongCorrosion resistant

Scalmalloy® is an aluminum-magnesium-scandium alloy designed for laser powder bed fusion. After a low-temperature heat treatment, it reaches about 510–530 MPa tensile strength and 480–500 MPa yield with 13–16% elongation, along with good corrosion resistance and thermal conductivity. Strength falls with temperature, while fatigue strength rises with milling and hot isostatic pressing. Scalmalloy® is well suited to lightweight brackets, thermal management components, waveguides, and ducts.

Standard (as-printed) Scalmalloy® (AlMgSc) has a matte gray, rough surface with visible layer lines, partially fused powder, and small marks where supports were removed. As built, it is more ductile but weaker than after aging.
