Feature: Black silicon carbide is very hard, sharp and brittle. Its grain edges are sharp and it is of acertain 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 abrasives 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
