Fine Aluminum Powder 1-100 Micron - Atomized Grade

Fine aluminum powder (1-100 micron, atomized grade) is a high-purity metallic powder produced through gas or air atomization, resulting in spherical particles with excellent flowability and uniform size distribution. It is widely used in industries requiring precise particle morphology, such as additive manufacturing, pyrotechnics, metallurgy, and coatings.

PRODUCT DETAILS

Product Features
1. High-purity Raw Materials:
Aluminum purity ≥99.7% (compliant with ASTM B214 standards) with low impurity content (Fe ≤ 0.15%, Si ≤ 0.10%).
Low oxygen content (≤ 0.1%) reduces oxidation risk, making it suitable for precision industrial applications.
2. Controllable Particle Size Distribution:
Adjustable from 1-100 microns (μm), supporting graded supply (e.g., 1-20μm, 20-50μm, 50-100μm).
Spherical particles account for >90% (excellent flowability), making them suitable for applications such as 3D printing and powder metallurgy.
3. Atomization Process:
Gas atomization (N₂/Ar shielding) results in highly rounded particles with minimal satellite particles.
Large surface area (3-8 m²/g) improves chemical reaction efficiency.
