Cobalt metal is mainly used for making alloy. Cobalt-based alloy is cobalt and chromium, tungsten, iron, nickel group made of one or more of the general term. Tool steel containing a certain amount of cobalt can significantly improve the wear resistance and cutting performance of steel. Stellite hardeners containing more than 50% cobalt do not lose their original hardness even when heated to 1000 ° C. Nowadays, these cemented carbides have become the most important material for use between gold cutting tools and aluminum. In this material, cobalt alloyed with other metal carbide grains together to make the alloy with higher toughness and reduce the sensitivity to impact, the alloy welding on the surface of the parts, the parts can make Life expectancy increased by 3-7 times.
