Cobalt Powder (Co Powder)

Product Information

Cobalt is a hard, grey metal which is ferromagnetic. It is usually found in association with nickel in arsenical ores, its abundancy in the Earth's crust being 20 ppm. Cobalt is relatively unreactive, being stable in air and only slowly attacked by dilute acids. It does not combine with hydrogen and nitrogen but it does react with carbon, oxygen and steam at elevated temperatures, producing CoO in the latter cases. Cobalt is insoluble to water and has a melting point of 1495°C and a boiling point of 2927°C. It is frequently used to produce magnetic and high strength superalloys.Cobalt alloys have good thermal and oxidation resistance, coupled with mechanical strength. The metal is also used in electroplating and its radioactive isotope, …‰Cobalt, is used in the treatment of cancer. Cobalt foils are produced from cast ingots for use in coating and thin film Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Ultra High Purity (99.9+%) thin-film foil, Thermal, and Electron Beam (E-Beam) Evaporation, Low-Temperature Organic Evaporation, Atomic Layer Deposition (ALD), Organometallic and Chemical Vapor Deposition (MOCVD) for specific applications such as fuel cells and solar energy.

Applications of Cobalt Powder

Cobalt powders are commonly used to manufacture superalloys which ar used to produce magnetic, wear- and corrosion resistant and high-strength products. Alloys based on cobalt powders are suitable for applications such as blades in jets and gas turbines where its temperature stability is important.

Packing of Cobalt Powder

Standard Packing:

Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 440 gallon liquid totes Special package is available on request.

ATTs’Cobalt Powder is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
