Black silicon carbide
black silicon carbide is a synthetic abrasive made from silicon and carbon fused into an extremely hard ceramic structure (2300–3000 knoop). iron-free and highly sharp, it delivers very aggressive cutting action, ideal for removing coatings, oxides, scale and tough surface contaminants. its high hardness and controlled friability produce clean, uniform surfaces on steel, stainless steel, cast iron, ceramics, glass and other hard materials. supplied in 25 kg bags.
