Core Physical Properties
1.Ultra-high hardness
Hardness up to 8000HV, 8 to 12 times that of carbide, efficiently cutting high hardness materials12.
2.Excellent wear resistance
Wear resistance 30 to 80 times that of carbide, significantly extending life16.
3.Excellent thermal conductivity
Thermal conductivity 700W/m-K (1.5 to 9 times that of Cemented Carbide), rapid heat dissipation to reduce thermal deformation12.
4.Low coefficient of thermal expansion
Only 0.9×10-⁶ to 1.18×10 -⁶ (1/5 of Cemented Carbide), dimensionally stable at high temperatures18.
Machinability Advantages
5.Low Coefficient of Friction
Coefficient of Friction 0.1 to 0.3 (Cemented Carbide 0.4～1), lower cutting force and lower energy consumption12.
6.Bonding resistance
Low affinity for non-ferrous metals (Aluminum, copper, etc.) and non-metallic materials, inhibits chip tumors12.
7.High-precision machining
Cutting edge sharpness up to the micron level, enabling Ra≤0.1 Mirror surface machining with Ra≤0.1μm
