Metallic cobalt, cobalt rods, cobalt belt, cobalt powder 

 Long-term supply of imports of the metal cobalt, cobalt bar, cobalt belt, cobalt powder, high purity cobalt powder, cobalt oxide, electrodeposition of cobalt, cobalt oxide, cobalt metal was silver-white, density 8.9 g / cm 3. Melting point 1495 ℃, boiling point 2870 ℃. Valence 2, and 3. Ionization energy of 7.86 eV. Of hard, malleable, and its hardness and ductility than the iron strong, but magnetic poor. And samarium, nickel, aluminum eutectic can get a good get magnetic steel. Does not occur with the role of water and air, but can also slow quickly to be hydrofluoric acid, ammonia and sodium hydroxide by erosion, as with all elements of performance change over price, and colored to produce chromium ions and compounds. Used to make super-hard heat-resistant alloys, magnetic alloys, tungsten carbide matrix, or binder. Cobalt alloys at high temperatures can still maintain its original strength and other valuable properties. Price below the market price, quality and acceptance by national standards.
