The chemical composition of the cobalt powder PC-1U
The use of PC-1y
Coating materials, manufacture permanent magnets, high-speed tool steels, heat resistant alloys by powder metallurgy. Cobalt magnets are resistant to heat, vibrations, not demagnetized in the most difficult conditions to 1121 ° C. PC-1U is the basis of corrosion-resistant, wear-resistant, heat-resistant alloys with special properties. Powder spraying cobalt increases the strength and performance details.
