Original Title: The Truth, Composition Analysis of Various Brands of Cemented Carbide Cemented carbide is used in industrial cutting, mining drill and other fields. Because of its hard characteristics and the requirements of application scenarios, its composition analysis has become a popular testing project. Usually, cemented carbide has a special coating process to make the surface of the blade smooth, thus reducing friction and making chip removal smoother. In addition, the toughness and hardness of cemented carbide are higher, and it has good thermal stability and chemical stability. All these require the analysis of alloy composition to study and control. Today we will give you a detailed analysis of various brands of cemented carbide. I.
