Cobalt
Product Description
Cobalt is a hard, lustrous, silver-grey transition metal known for its magnetic properties, strength, and ability to contribute to heat and wear resistance in specialized alloys. It is an important industrial raw material used in metal manufacturing, rechargeable battery materials, catalysts, pigments, and other technical applications.
Cobalt is commercially available in different forms, including metal cathodes, pieces, briquettes, granules, and powder. Cobalt compounds, such as cobalt oxide, cobalt sulfate, and cobalt carbonate, have different chemical properties and applications and should be specified separately when purchasing.

MA Associates provides product information and supply inquiries for industrial buyers. Product form, grade, purity, packaging, and availability should be confirmed according to the intended application.
