Description
Aluminum 6061 Alloy Powder
Size: -325 mesh
Form: Silvery-Gray Powder
Product Overview
Aluminum 6061 Alloy Powder is a versatile, precipitation-hardened aluminum alloy composed primarily of aluminum, magnesium, and silicon. This alloy is renowned for its excellent corrosion resistance, moderate-to-high strength, outstanding workability, and good surface finish after processing. Thanks to its finely tuned elemental composition and uniform particle size distribution (-325 mesh), it is suitable for a wide range of structural, mechanical, and additive manufacturing applications.
This powder form enables efficient sintering, compaction, and thermal spraying, making it ideal for use in powder metallurgy, additive manufacturing (3D printing), and coating technologies.
