What is Cobalt Powder !!. 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 salts (primarily cobalt aluminate, known as “Cobalt Blue“, or “Thenard’s Blue”) have been known of and used for centuries to provide a blue colouration to paints and ceramics. 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.
What is Cobalt Powder !! Small particles with an approximately defined size range. Those materials described as alloy precursors are not true alloys – they are made by sintering a blend of powders of the component metals to achieve alloying by diffusion. The resultant cake is ground and sieved to the required particle size range. Unless otherwise stated, the particle sizes shown are for guidance only. We do not guarantee either any particular size distribution between the quoted minimum and maximum sizes, or a specific particle shape.
Cobalt powder by Grades
What is Cobalt Powder !! Cobalt powder has three forms for reduced, electrolytic and atomized. It’s one of the key ingredinents of spuerhard alloy. The properties determined the bonding poperty, strength and toughness of spuerhard alloy. It is widely used for hard alloy, diamond tool, high temperature alloy, magnetic materials of metallurgical products; and aslo used for making rechargeable batteries, industrial blasting agent, rocket fuel and medical products.
What is Cobalt Powder !! Cobalt based alloy powder are hard alloy powder which can resist various wear, corrosion and oxidation at high temperature. It contains considerable proportion of Cr and W and a small amount of Ni, Mo, Si, C, Nb, Ta elements, and the Co is the main ingredinent. These cobalt alloy powders are used in overlayed welding, spray welding process, which also can fabricate casting and powder metallurgy components, such as high temperature pressure valve, sawthtooth and helical rotor.
