    Cobalt Powder
  • Cobalt Powder
  • Cobalt Powder
  • Introduction: 


    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.

    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.

    Most of our customers are alloy fabrication companies and coating companies from all over the world. They ordered a large quantities for one time. The cobalt powder supplier AEM provides high density powders with customized sizes. If you did not find the size you need, please email us. Or you have any questions about powders, please contact us. We'll be very glad to provide helps.
     

    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 manufacturing of Diamond Tools. Main Diamond Tools which are produced using Cobalt are Diamond Segments, Tool Wires, Tool Blades, etc which are used for cutting of Stones such as Marbles, Granite, etc.

    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 carbide. These hard phases have a strengthening efect, giving such alloys high hardness and strength at temperature under 800℃. The Coblat-Chromium-Tungsten-Carbide alloys generally have exellent 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 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.
