Cobalt powder

Technical characteristics

Cobalt powder is a highly-dispersed mass that is made by electric or recovering method. Cobalt is a metal of blue-black color. This is an element of periodic table with a number 27. It is designated as Co. Melting point constitutes 1495 °C, density is 8.9g/cm3, and boiling temperature is 2957 °C. It is often used as an alloying component of heat-resistant alloys for manufacture of high-speed engineering steels and making of hard powder alloys and high-magnetic material, where it performs a jointing role.

Application

Cobalt powder PK-1u is widely used in powder metallurgy for manufacture of hard alloys, permanent magnets, high-speed engineering steels, corrosion and heat resistant alloys, paints and lacquers.

Permanent magnets that contain cobalt possess resistance to vibration, high temperatures, high resistance to demagnetization. At a temperature of 1121 °C, cobalt is degaussed. Corrosion resistance and heat resistance allow using this cobalt powder in the capacity of alloying component for steels with special properties. Cobalt spraying is applied in order to increase corrosion protection of details. Powder cobalt is also used in manufacture of blue paints.
