1¡¢Variety and Applying fields of Synthetic Diamond and CBN (Cubic Boron Nitride):
Synthetic Diamond and CBN (Cubic Boron Nitride):
Diamond is the hardest material at present, Synthetic Diamond is synthesized by the means of static pressure catalysis & experience high temperature with high pressure, it suits to proceed sintered-carbide and other hard-brittle nonmetal materials¡£
The hardness of CBN is just inferior to Diamond, compare with the later, CBN owns the characteristics of excellent thermal stability and large chemical inertia with iron family metal etc, it suits to process metal-materials for instance high-vanadium steel, high-speed steel and alloyed steel etc.
