Physical and Mechanical Properties
1.Ultra-high Hardness and Wear Resistance
Micro-hardness reaches HV3000～5000, second only to diamond, 3～5 times that of cemented carbide.
When processing hardened steel (HRC＞50), the life span is more than 10 times higher than that of cemented carbide, and it is especially suitable for super-hard materials such as high-chromium cast iron, cold-hard cast iron, etc.
2.Chemically inert and low friction
It does not react with ferrous metals at 1200-1300°C. The coefficient of friction is only 0.1~0.0%.
The coefficient of friction is only 0.1～0.3 (0.4～0.6 for cemented carbide), which reduces the accumulation of chip tumors and improves the surface quality.
3.Outstanding thermal conductivity
Thermal conductivity 700~1300W/(m-K), which is 3~1300W/(m-K) higher than that of cemented carbide. The thermal conductivity is 3-6 times higher than that of Cemented Carbide, which can quickly export cutting heat and reduce thermal deformation of the workpiece.
