GC-GPA is a green, friable, medium bulk density silicon carbide abrasive grain.

Description:

GC-GPA is a green, 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 to get a complete range of grit sizes.

Applications:

GC-GPA can be used in refractory, ceramic and abrasive area, such as making vitrified bonded grinding wheels, resin bonded tools, to process cast iron, hard alloy, tatium alloy and high speed steel. As loose grains, it is widely used for polishing none-metal material like ceramic, glass, stone, agates, jades and jewels.
