Abrasives
We produce Silicon Carbide Abrasives as FEPA Standard, include bonded abrasives(F-Grit) / coated abrasives (P-Grit)/and we also can produce JIS series

F-Grit

F type Black SiC: We offer F TYPE black silicon carbide powders for the abrasive wheel, slurry, refractory and ceramic industries. Abrasive black silicon carbide powders specifically manufactured to be used for general abrasive applications in bonded abrasive tools, lapping and polishing processes. With a lower hardness and abrasive capacity than diamond or boron carbide, it is widely used for grinding nonferrous materials, finishing tough and hard materials, as well as filling up ceramic parts due to its lower cost. It is commonly used in the following applications:
Common Uses:

  • Silicon carbide powders are used heavily in ceramic, metal lapping, and polishing applications:
  • Slicing of silicon carbide wafers
  • Rock and stone polishing and engraving
  • Slicing, lapping, and polishing glass and germanium wafers
  • Lapping of piston rings and gears
  • Grinding of nonferrous materials
  • Finishing tough and hard materials
  • Bonded abrasive tool applications

Sizes Available: Grit sizes range from coarse grades down to a 2000 mesh size.

Grading: FEPA Standard
The mean diameters of macrogrits shown in the table are estimated and for information only, the FEPA "F" standard defines them as a range and not a single value.

The particle size distribution of macrogrits is determined by sieving, while the microgrits have been measured by sedimentation (photosedimentometer).
