Alpha-type silicon carbide abrasive material used for precision lapping of grinding cloth, ultra-fine precision grinding stones, cast iron, brass, etc.
"C" is a black silicon carbide abrasive material commonly referred to as Carborundum. It is composed of α-type silicon carbide crystals obtained by thermally reacting silica and coke at high temperatures above 2000°C in an electric resistance furnace. The products derived from our unique manufacturing process consist of a stable cutting edge and a particle size distribution suitable for abrasive processing, enabling excellent surface finishing. 【Features】 ■ Composed of α-type silicon carbide crystals ■ Superior toughness compared to GC ■ Suitable as a material for abrasive cloth, ultra-fine precision grinding wheels, and for precision lapping of cast iron, die-casting, copper, aluminum, stone, and glass for photomasks ■ Also suitable for precision honing and dicing of semiconductor crystals, etc. *For more details, please refer to the PDF document or feel free to contact us.
