Description:

GC-GPA is agreen, friable, medium bulk density silicon carbide abrasive grain.To get this kind of grains, we specially process the ingots,separate the magnetic material, and sieve the grains carefully toget a complete range of grit sizes.

 

Applications:

GC-GPA can beused in refractory, ceramic and abrasive area, such as makingvitrified bonded grinding wheels, resin bonded tools, to processcast iron, hard alloy, tatium alloy and high speed steel. As loosegrains, it is widely used for polishing none-metal material likeceramic, glass, stone, agates, jades and jewels.
