Abrasive Content Black Eco-friendly Silicon Carbide PowEPTwith Great Good quality
Black silicon carbide (C) is produced by petroleum coke, quality silicon sand and appended with salt in an electric powered arc furnace at substantial temperatures. The hardness and brittleness are reduce than that of inexperienced silicon carbide. The materials are employed to grind solid iron, non-ferrous metals, rubber, leather, plastic, wood, mineral rocks, and many others. It can also be employed to manufacture substantial-course refractory items.

Green silicon carbide (GC) is created by petroleum coke, quality silicon sand and appended with salt in an electric powered arc furnace at high temperatures. The hardness is increased than artificial corundum, but decrease than diamond. Mechanical power is larger than corundum. The materials are employed to grind hard and brittle steel, non-ferrous metals like copper, brass, aluminum and magnesium, and non-metallic resources this kind of as gem, optical glass, ceramics, and many others.
