Description:

high purity green silicon carbide
making abrasive grinding wheels
making precise sharpening stone

Description:

GC-GPA is a green,friable, medium bulk density silicon carbide abrasive grain. To getthis kind of grains, we specially process the ingots, separate themagnetic material, and sieve the grains carefully to get a completerange of grit sizes.

 

Applications:

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