Cobalt powder. Brand chemical composition.
Cobalt — the 27th element of the chemical periodic table, which has a symbol of Co metal with bluish-black tint. The proportion of cobalt is 8.9 g/cm3. Fine powder of cobalt recovery is made or the method by electrolytic method. Widely used in powder metallurgy. Serves as an alloying additive heat-resistant alloys, magnetic materials, high-speed steel.

Chemical composition cobalto powder PC-1U
Application of PK-1U
Coating materials, manufacturing of permanent magnets, high speed tool steel, heat-resistant alloys by powder metallurgy methods. Cobalt magnets are resistant to heat, vibrations, is not demagnetized in the most difficult conditions to a temperature of 1121 °C. PC-1U is the basis of corrosion-resistant, wear-resistant, heat-resistant alloys with special properties. Cobalt powder coating enhances durability and performance details.
