Aluminum (Al) Micron Powder (99.9+%, 20–35 µm, Spherical)

Description

Aluminum (Al) Micron Powder (99.9+%, 20–35 µm, Spherical)

Aluminum (Al) Micron Powder is a high-purity metallic powder with a particle size range of 20–35 µm and a spherical morphology. With 99.9+% purity, this powder provides excellent electrical and thermal conductivity, lightweight characteristics, corrosion resistance, and reactivity. Its balance of micron-scale particle size and spherical shape makes it particularly useful in aerospace, pyrotechnics, pigments, coatings, and epoxy composites.

Aluminum powders at this particle size range are especially suitable for industrial applications where high stability, controlled reactivity, and uniform dispersion are required, making them a preferred choice for both engineering materials and specialty chemical uses.
