Description

Chromium (Cr) Micron Powder – Spherical (99.9%, 15–60 µm)

Chromium (Cr) Micron Powder is a high-purity spherical metallic powder with a particle size range of 15–60 µm and purity of 99.9%. Known for its exceptional hardness (Mohs 9), high melting point (1875 °C), and excellent corrosion resistance, chromium powder is indispensable in aerospace, advanced alloys, ceramics, electronics, and nuclear technologies.

The spherical morphology provides excellent flowability, packing density, and uniform sintering behavior, making it highly suitable for powder metallurgy, additive manufacturing, and thermal spray coatings. Chromium’s oxidation resistance and high hardness make it one of the most reliable elements for enhancing wear resistance and mechanical performance in alloys and coatings.
