SND-MDW Professional Synthetic Micron Diamond Powder For Silicon Wafer Cutting  Diamond Wire 1. Micron Diamond Powder Introduction    

SND-MDW has a high strength blocky crystal shape, concentrated particle size distribution, Uniform particle size and shape. Specially designed for making silicon wafer cutting diamond wire, jewelry saw, semiconductor saw.

2. Specification of Micron Diamond Powder

SND-M05  0-0.125~40-60 SND-M10  0-0.125~40-60 SND-M15  0-0.125~40-60
Irregular crystal shape,  impurity content and particle  size distribution, can be used  in resin and vitrified bond.  Suitable for high efficient  grinding and polishing  applications, like stones,  tiles, Jade & gem, etc. Irregular crystal shape with  relatively concentrated  particle size distribution,  low impurity content. High  efficiency. Can be used in  resin, vitrified, metal bond  and electroplated products.  Block grain, relatively  concentrated particle size  distribution, tiny impurities,  favorable hydrophilic   performance. Suitable for  high requirement lapping,  polishing, can be used  for  PCD high quality diamond  paste and slurry and other  high quality diamond products.
SND-M/DW 0-0.125~40-60 SND-M/PCD 0-0.125~40-60 SND-M/PL 0-0.125~40-60
Uniform particle size and shape. For making silicon wafer cutting diamond wire, jewelry saw, semiconductor saw.

Specially designed for 

PCD/PDC application, high 

strength blocky crystal shape, 

concentrated particle size 

distribution, very low impurity, 

low Si content, good thermal 

stability and wear resistance. 

Also can be used on high 

quality metal bond, vitrified 

bond and electroplated 

products.

Poly-like diamond has the  similar feature as the  polycrystalline diamond, but  lower cost. It is made of the  sorted diamond micron, with  a special chemical treatment,  the poly-like diamond has  muti deavtivation edges,  these honeycomb edges can  help the polishing surface out  of scratches.
