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.
