Cobalt Powder

Cobalt powder’s three forms are reduced, electrolytic, and atomized. It’s one of the key ingredients of superhard alloy. The properties determined the bonding property, strength, and toughness of superhard alloy. It is widely used for hard alloy, diamond tools, high-temperature alloys, magnetic materials of metallurgical products, and making rechargeable batteries, industrial blasting agents, rocket fuel, and medical products.

Cobalt-based alloy powder is a hard alloy powder that can resist various wear, corrosion, and oxidation at high temperatures. It contains a considerable proportion of Cr, and W, and a small amount of Ni, Mo, Si, C, Nb, Ta elements while Co is the main ingredient. These cobalt alloy powders are used in overlayed welding, spray welding, which can also fabricate casting, and powder metallurgy components, such as high-temperature pressure valves, sawtooths, and helical rotors.

Most of our customers are alloy production companies and coating companies from all over the world. They ordered large quantities at one time. The cobalt powder supplier ARS provides high-density powders with customized sizes. If you did not find the size you need, please email us or have any queries about powders, please contact us. We will be delighted to provide help.

Cobalt Metal powder

 

Cobalt metal powder is specifically designed and manufactured for use in high-quality cemented carbide and related products. The hard metal industry demands Cobalt spherical powder with high standards of purity, fine particle size, and consistent particle size distribution. Cobalt atomized powder is used for the manufacturing of Diamond Tools. The main diamond tools produced using cobalt are diamond segments, tool wires, tool blades, etc, which are used for cutting stones such as marbles and granite.

Cobalt-based Alloy Powder (Thermal Sparaying and Welding Powder)

 

Cobalt-based alloys typically contain tungsten and carbon for strengthening. Carbon has low solid solubility in cobalt, and therefore most of its partitions are in WC, W2C, M6C, or other carbides. These hard phases have a strengthening effect, giving such alloys high hardness and strength at a temperature under 800℃. The Cobalt-Chromium-Tungsten-Carbide alloys generally have excellent properties to resist high-temperature, oxidation, and thermal fatigue.

Cobalt has a hexagonal-closed-packed (hcp) crystal structure at temperatures below 417℃. Intrinsically, it has a low coefficient of friction resulting in excellent wear resistance. At temperatures above 417℃, cobalt transforms from HCP to FCC (face-centered-cubic) crystal structure, thereby generating thermal stress. Therefore, it is recommended that in weld overlaying and spraying, the parts being coated are pre-heated to 500-600℃ to avoid cracking in the coating or overlay.
