Description
Cobalt (Co) Micropowder / Powder – 99.9% Purity, 800 nm, Metal Basis
Cobalt (Co) Powder is a high-purity (99.9% metal basis) fine metallic powder with an average particle size (APS) of 800 nm. Produced with advanced processing techniques, it offers excellent uniformity, high density, and stable performance.
With a bulk density of 0.8–1.1 g/cm³ and a true density of 8.92 g/cm³, cobalt powder is valued for its exceptional magnetic properties, high melting point (1495 °C), and chemical stability. It is widely used in magnetic materials, electromagnetic wave shielding, data storage, and biomedical applications.
Thanks to its consistent particle size and high purity, it is also suitable for specialty alloys, battery materials, and precision manufacturing.
