Description
Aluminum Micron Powder, Spherical, 12–18 µm (Propellant Grade)
Spherical Aluminum Powder, 12–18 µm (MIL-PRF-23950B) is a high-purity aluminum powder produced by gas atomization, engineered for applications requiring controlled particle size distribution, high sphericity, and consistent surface characteristics.
Manufactured via advanced gas atomization processes, this material offers reliable performance in demanding industrial and energetic material systems where reproducibility and material consistency are critical.
The product is manufactured under strict process control to ensure uniform morphology, narrow particle size distribution, and low levels of impurities. Its characteristics align with commonly referenced requirements associated with MIL-PRF-23950B-class spherical aluminum powders, subject to customer qualification and testing protocols.
