Cemented carbide inserts are mainly made of solid carbide as the matrix through multiple production processes. They have high hardness, wear resistance, good toughness, heat resistance and corrosion resistance. The choice of cemented carbide blade grades should be based on requirements.

Tungsten alloy balance weight can be simply understood as a weight that is mainly made of metal tungsten material, so it is also called tungsten alloy weight. Because of its excellent physical and chemical properties, it is favored by researchers in military, national defense, aerospace, aviation, navigation, automotive, medical, electronics, petrochemical and other fields.

The improvement of the performance of tungsten-copper alloy is a concern of modern manufacturers. The alloy is a uniformly mixed structure of two-phase monomers of tungsten and copper. It is neither miscible nor intermetallic. It is a typical pseudo alloy.

In 1792, the Swedish chemist Elm used a mixture of charcoal and molybdic acid blended with linseed oil and burned in a sealed manner to obtain molybdenum. Because metallic molybdenum has the advantages of high strength, high melting point, corrosion resistance, and wear resistance
