Product Description

Cobalt-based alloy is resistant to various types of wear and corrosion and high-temperature oxidation. It was invented in 1907 by American Elwood Haynes. Cobalt alloys are mainly composed of cobalt, containing a considerable amount of nickel, chromium, tungsten, and a small amount of alloying elements such as molybdenum, niobium, tantalum, titanium, lanthanum, and occasionally iron. Our company adopts powder metallurgy, casting, forging, welding and other processes to ensure the excellent performance of materials. Among them, the powder metallurgy technology is remarkably mature, the product performance is stable, the precision is high, and mass production can be carried out. Cobalt alloys are suitable for conditions that require high-temperature, wear, and corrosion resistance. The more complex the working conditions are, the more the advantages of Cobalt alloys can be reflected.
