CVD diamond film and its products

CVD diamond , a new type of diamond sheet material, can be used in many industries

CVD diamond is chemical vapor deposition diamond. CVD diamond does not contain any metal or nonmetal additives. It has high hardness, high wear resistance, easy processing, high thermal conductivity, high light transmission band width and chemical stability against acid and alkali corrosion. At the same time, due to its ability to obtain large-size diamond, it is possible to apply diamond with excellent acoustic, optical, electronic and semiconductor material functional properties in addition to hardness. CVD diamond films have been widely used in machining, wear-resistant parts, electronic devices, optical windows and other fields.

Precision dressing roller and blank --- replace natural diamond, dressing more efficient, better dimensional consistency, CVD diamond has high wear resistance, low friction coefficient, so it is a very ideal material for precision dressing roller blank and wear-resistant parts. The dressing tool with CVD diamond as raw material has long service life, high dressing efficiency and stable quality.

The range of blank thickness is 0.3-2.0 mm, and the cutting accuracy is ± 0.02

CVD composite blade head and blade

CVD diamond is a polycrystalline diamond material prepared by chemical vapor deposition, CVD diamond does not contain any metal or nonmetal additives. Because of its excellent superhard wear resistance and good toughness, CVD diamond can successfully process most non-ferrous metal materials and a variety of metal materials, such as aluminum, silicon aluminum alloy, copper, copper alloy, graphite, ceramics and various reinforced glass fiber and carbon fiber structural materials. The blade can be customized according to the needs of users.


CVD diamond heat sink

It is mainly used in laser diode heat sink for optical communication, high-power diode array transition heat sink for pumping, high-density IC packaging materials, circuit board of power microwave devices, etc. it is an ideal heat sink material for high-power electronic and optoelectronic devices.


 The performance parameters of CVD diamond film are as follows:
