JCB TSP polycrystalline is a diamond polymer sintered with diamond and binder under high temperature and high pressure. At the same time, the thermal expansion coefficient of the binder is close to that of diamond, so its heat resistance temperature can reach about 1200°. JCB TSP polycrystalline has the characteristics of high wear resistance, high thermal stability and dense and uniform structure. TSP polycrystals are widely used in the manufacture of petroleum, geological drill bits, diamond processing and machining tools. TSP polycrystals can be processed into various shapes and specifications (such as: cylindrical, conical, square, triangle and shaped polycrystals) to meet the needs of our customers.
The company uses different formulations and processes, refined by high temperature and high pressure of the bit polycrystal and retention polycrystal, it has a high wear ratio, and the use cost is very low compared with natural stone, is the ideal material for the production of petroleum geological drill, has been used by major oil fields and drill manufacturers at home and abroad. Products can be processed into various specifications, various shapes (such as: cylindrical, conical, square, triangle and shaped polycrystal) to meet the needs of our customers.
