CVD diamond is Chemical Vapor Deposition synthetic single crystal diamond material.
CVD diamond is manufactured by means of a diamond synthesis technology in which a low pressure reactor is used to combine a thermal or plasma activating agent with a gas-phase carbon to produce a chemical reaction which results in polycrystalline

Properties

Vickers hardness 7000-10000 kg/mm2
Thermal Stability: ~1200˚C.
Density:3.51g/cm³
Young’s modulus:1000-1100Gpa
Thermal conductivity: >8W/cm．K
Chemical stability: insoluble in alkali and acid
Friction coefficient(contrary to the steel):<0.1
non-oriented

Hole size range

Semifinished:From 0.010mm to 0.800mm
Finished:From 0.020mm to 1.200mm

Advantage:

Wear resistance and temperature resistance are similar as ND,SMCD,better than PCD material.

Lower price that nature diamond dies.

No directional wear,because it's isotripic.

Applications
hard metal fine wire,tungsten wire, molybdenum & stainless steel wire,alloy wire,copper wire and other fine wire.
