Aluminum 7A76 20μm-63μm
Aluminum 7A76 powder, with a particle size range of 20-63 µm, is specifically engineered for fusion-based additive manufacturing, bringing the high strength, durability, and fatigue resistance of 7xxx series alloys to laser powder bed and DED systems. Aluminum 7A76 incorporates grain refiners that inhibit solidification cracking, which allows for successful 3d printing of complex designs and lightweight assemblies for aerospace, defense, and automotive applications. Furthermore, the equiaxed particle shape facilitates excellent powder flowability and part density, which is crucial for achieving precise, high-quality prints.
Powder designed for
Powder Bed Fusion
Directed Energy Deposition
MPW metal powder is manufactured utilizing our DirectPowder™ process. The mechanical only, high-yield, no-melt technology maintains the microstructure and temper of the bar stock material, yielding a consistent size and shape and narrow particle size distribution.
