Green Silicon Carbide

Features: Green silicon carbide is in high hardness and brittle. Its grain edges are sharp and it is of excellent capacity of heat transmission. Its purity is higher than that of the black silicon carbide.

Application: Green silicon carbide is suitable for fine grinding of and lapping hard and brittle materials such as tungsten carbides, optical glass, jewel, agate and so on.

Our silicon carbide abrasive grains are manufactured according to the standards as follows:

FEPA--for bonded abrasive tools F8-F2000
FEPA--for coated abrasive tools P12-P2500
JIS abrasive grain size: # 8--# 8000
