Description

Cobalt (Co) Micron Powder – Spherical (99.9%, 15–53 µm, Metal Basis)

Cobalt (Co) Micron Powder is a spherical metallic powder with a particle size range of 15–53 µm (325 mesh) and a high purity of 99.9%. With its hexagonal crystal structure, cobalt exhibits excellent hardness, wear resistance, corrosion resistance, and magnetic properties, making it highly valued in superalloys, coatings, catalysts, and industrial manufacturing.

The spherical morphology of this powder provides improved flowability, packing density, and uniformity, making it particularly suitable for powder metallurgy, additive manufacturing, and thermal spray coatings. Its combination of mechanical durability, electrical conductivity, and thermal stability makes spherical cobalt powder indispensable for advanced engineering applications.
