Chromium (Cr) Micron Powder (99.9%, 100 Mesh)

Description

Chromium (Cr) Micron Powder (99.9%, 100 Mesh)

Chromium (Cr) Micron Powder is a high-purity metallic powder with a particle size of 100 mesh and a purity of 99.9%. With its high hardness (Mohs 9), excellent corrosion resistance, and high melting point (1875 °C), chromium powder is widely used in alloy production, catalysts, coatings, and specialized industrial processes.

Its cubic body-centered crystal structure (BCC) provides superior mechanical stability and wear resistance, making it a valuable raw material in metallurgy, stainless steel production, and industrial catalysts. The fine micron size ensures effective dispersion and uniformity in both powder metallurgy and chemical applications.
