Polycrystalline Diamond and

Polycrystalline CBN

Polycrystalline Diamond and Polycrystalline CBN are sintered with micron grain diamond and CBN in the condition of high temperature and high pressured.

They have high wear-ability, high thermal resistant,
high compressive strength and toughness of shock resistance, and are widely used in geological exploration, recovering petroleum, jewely industry and machining operation and so on. At present, main specification is as follows. Other specifications not mentioned on the following list are available according to customer's requirements.

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,glass,wood,fiberboard and etc.We adopt advanced technology of STCR(seeep through catalyst recrystallization) in our newly developed PDC,which helps realizing the direct bonding among diamond particles.This kind of PDC is of very high hardness,excellent wearability and good toughness.

Our product has a stable property and its quality has reached advanced level at home.
