Diamond tools

Copper and copper alloy powder, copper powder, bronze powder, brass powder

Along with boron nitride, diamond is among the “super hard cutting materials” and it is used in the form of polycrystalline synthetic diamond powders to manufacture diamond tools.

To do so, a precisely defined mixture of metal powder and diamond powder is sintered onto the hard metal core of the cutting tool. The metal matrix binds the diamond particles in defined positions. If a diamond particle is worn down, the soft metal matrix is removed to the point that the next diamond particle on the surface appears and can be used (shark tooth principle).
