Product Description

Polycrystalline Diamond Powder Description

SIGNI detonation polycrystalline diamond (PCD) is similar with natural Carbonado in the structure. Therere thousands of micro crystallites size of 3-10nm integrated together into polycrystalline structure through unsaturated bond. PCD has many more cutting surfaces, resulting in the higher removal rates. It also has good self-sharpening properties. The polycrystalline structure will open every time new sharp edges introduced by releasing an outer layer of dull crystallites. The polycrystalline diamond can lap and polish any materials fast while produce the smoothest surface without scratches.
