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.
Applications
Electromagnetic Wave Absorption & Shielding – EMI/RFI protection for electronics
Mobile Device Radiation Shielding – Coatings for cell phones and electronic devices
Ferrofluids – For smart material systems and engineering applications
High-Density Magnetic Storage – Data storage media
Magnetic Inks & Toners – Printing and security features
MRI Contrast Agents – Biomedical imaging
Specialty Alloys – Aerospace, automotive, and tool manufacturing
