In the field of superhard materials, CVD diamond (chemical vapor deposition diamond) is redefining processing limits with its unparalleled performance. Unlike traditional high-pressure synthetic diamonds, CVD technology creates single or polycrystalline diamond materials with a purity of up to 99.9% by depositing carbon atoms and growing them in a low-pressure environment.
The excellent characteristics of CVD diamond include:
Extreme Hardness: HV10000 and above, three times that of tungsten carbide
Ultra-High Thermal Conductivity: 2000W/m·K, five times that of copper
Nanometer Smoothness: Surface roughness can reach Ra 0.02nm
Perfect Lattice Structure: Free of metal catalyst contamination
For supreme tool dealers, CVD diamond tools show remarkable advantages in processing high-silicon aluminum alloys (Si>18%).
In the optical field, CVD diamond window materials are prized for their:
Full-spectrum transparency from ultraviolet to far-infrared
Laser damage threshold up to 10kW/cm²
Sand and dust erosion resistance twenty times greater than sapphire
making it an ideal choice for high-energy laser systems and infrared imaging equipment.
