Cobalt powder. Brand chemical composition.

Cobalt powder. Brand chemical composition.

General characteristics

Cobalt powder is a fine mass produced electrically or by recovery. Cobalt is a metal blue-black color element periodic table number 27, denoted by Co. Has a melting point of 1495 °C density 8.9 g/cm3, boiling point 2957 °C. is Most often used as an alloying component of high-temperature alloy, for the manufacture of high speed tool steels and in the production of hard powder alloys and hard magnetic materials, where it performs a connecting role.

Use

Cobalt powder PC-1U is widely used in powder metallurgy for the production of hard alloys, permanent magnets, high speed tool steels, corrosion and heat resistant alloys and paint products.

Permanent magnets which contain cobalt powder, resistant to vibrations, high temperatures, high resistance to demagnetization. At t° more than 1121 °C cobalt demagnetized. Wear resistance, corrosion resistance and heat resistance allow you to apply this powder as the primary component for steels and their alloys as an alloying component with special qualities. To increase the protective properties of the parts, as a rule, they make the cobalt deposition. It is also used in the manufacture of dyes blue.
