High-Strength Aluminum Alloy Powder

Description

Scalmalloy® is a high-performance aluminum alloy powder material composed of selected elements such as aluminum, magnesium, and scandium, specifically designed for additive manufacturing. It features a bimodal microstructure where fine equiaxed grains are separated by coarser columnar grains, with Sc added at a hypereutectic point (eutectic content 0.4-0.55wt%), while Mg refines grains and enhances strength. Compared to conventional aluminum alloys, Scalmalloy® exhibits exceptional properties. Tensile strength reaches 533MPa, yield strength up to 527MPa, and it maintains good ductility under high stress with elongation exceeding 10%, outperforming traditional 7-series aluminum alloys. With a lower density, Scalmalloy® is approximately 60% lighter than titanium alloys at equal volume, significantly reducing structural weight, making it suitable for weight-sensitive applications.
