1. 20 years experience.
2. Reduce the damages to the diamond during high temperature grinding.
3. Improve thermal conductivity

Product Description

The coated diamond has a close coating and is excellent in adhesiveness between diamond and the coating, and thus can be used for preparing a composite material which exhibits excellent properties inherent in diamond more faithfully. There are breeds: nickel  plated, titanium plated, copper plated and chrome plated. The metal coated diamonds have the following features:
1. Enhance the bonding between the diamond crystal and the resin bond.
2. Improve thermal conductivity during grinding. Since the metal coating on the synthetic diamond particles transfers heat slower than diamond particles do and most of heat can be transferred to inosculating intermedium, the synthetic diamond can be protected from Overheating.
3. Reduce the damages to the diamond during high temperature grinding process. By being coated, diamond can keep its original natures, instead of being carbonized and oxidized.

DiamondctNi coated35/40
-325/400Suitable for resin bond system or vitrified bond system. Its surface
structure with spiky protrusion gives diamond the superior
attachment to the bond matrix and excellent heat conductivility,
Used for diamond grinding wheel and so on, especially for diamond
flexible polishing pad. Wet milling has better effects.DJN2ctCu coated35/40
-325/400Adequate for ferrous metal, hard metal or resin bond grinding wheel,
Able to enhance the mechanical attachment of diamond, and thereby
  expand the life of wheel and  improve  the effects of surface finish. Wet
milling has better effects.DJCctNi coated35/40
-325/400Suitable for resin or bronze bond grinding wheel series. Able to
enhance the mechanical attachment of diamond, and thereby
expand the life of wheel and  improve  the effects of surface finish.
Dry milling has better effects.DJTctTi coated35/40
-325/400Used for metal bond products. Able to improve the attachment of
diamond and protect diamond from graphitization by metallurgical
bonding between Ti and metal, and thus ensure the intensity and 
application features of diamond.
