PDC(polycrystalline diamond composite) is widely used for oil,gas,engineering drilling bits and also used in machining aluninum alloy,copper,brass,plastics,rubber,ceramics,tungsren carbide,and etc.We adopt advanced technology of STCR(sweep through catalyst recrystallization) in our newly developed PDC,which helps realizing the direct bonding among diamond particles.Our product has a stable property and its quality has reached advanced level at home.
