ZZDM can supply both mono crystalline and poly crystalline CVD diamond.
Our DMCVD can be divided into several grades according to different application, which are for industrial usages, for gem making and optical utility.

CVD Diamond Dressing Tool Blanks
For duressing tool blank CVD diamonds, we have three grades: Standard grade-CVDS, medium grade-CVDM and premium grade-CVDP.
Advantages:
* Pure diamond with high hardness and without binder phase
* High wear resistance
* Excellent thermal stability
* High abrasionApplications:
* Single point diamond dressing tool
* Multipoint diamond dressing tool
* Diamond dressing rotary wheel
CVD Diamond Wire Drawing Die Blanks
The CVD diamonds for wire drawing die are normally hexangular shape, with good abrasion resistance, high hardness (8000~10000Kg/mm2) and high thermal stability (~1200藲C protected by Argon), can be widely used in wire drawing of stainless steel, tungsten, molybdenum, copper, aluminum and many other alloy materials.
CVD Diamond Cutting Tool Blanks
Applications: Non-ferrous metals, silicon aluminum alloy, copper and copper alloy, ceramics, plastic and rubber, glass, graphite, etc.
Tools: Surgical knives; cutting tool inserts; drill bits; reamers etc.
CVD Diamond Composite (with TC substrate)
Standard surface finish is lapped to remove growth features. NP is defined as unprocessed material.Polycrystalline Diamond
