Black Silicon Carbide

Features: Black silicon carbide is very hard, sharp and brittle. Its grain edges are sharp and it is of a certain capacity of heat transmission.

Application: Black silicon carbide is ideally suited for grinding cast iron, non-ferrous metal, rubber, leather, stones, and wood etc. It is also can be used as high grade refractory material.

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

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