3D Printing Alloy 21
Description
Alloy 21 is a cobalt-based alloy with cobalt as the main component, containing a considerable amount of chromium, molybdenum and small amounts of nickel, carbon and other alloying elements, and occasionally iron. It is a cemented carbide that is resistant to all types of wear and corrosion as well as high temperature oxidation. Our 3D printing alloy 21 is a vacuum induction melted, argon gas atomized, and spherical powder for additive manufacturing. It can be used in aerospace, electric power, petrochemical, shipbuilding, machinery, electronics, environmental protection and other industries.
