Description:

1.friable, medium bulk density silicon carbide abrasive grain
2.be used in refractory, ceramic and abrasive area

Description:

GC-GPA is a green, friable, medium bulk density silicon carbideabrasive grain. To get this kind of grains, we specially processthe ingots, separate the magnetic material, and sieve the grainscarefully 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 bondedtools, to process cast iron, hard alloy, tatium alloy and highspeed steel. As loose grains, it is widely used for polishingnone-metal material like ceramic, glass, stone, agates, jades andjewels.
