High Top quality Abrasive Black Inexperienced Silicon Carbide Grit PowEPTwith Affordable Value
Black silicon carbide (C) is created by petroleum coke, quality silicon sand and appended with salt in an electric powered arc furnace at substantial temperatures. The hardness and brittleness are lower than that of inexperienced silicon carbide. The resources are employed to grind forged iron, non-ferrous metals, rubber, leather, plastic, wooden, mineral rocks, and many others. It can also be utilized to manufacture higher-course refractory products.

Inexperienced silicon carbide (GC) is made by petroleum coke, high quality silicon sand and appended with salt in an electric powered arc furnace at higher temperatures. The hardness is higher than synthetic corundum, but reduce than diamond. Mechanical toughness is greater than corundum. The materials are used to grind difficult and brittle metallic, non-ferrous metals like copper, brass, aluminum and magnesium, and non-metallic components this sort of as gem, optical glass, ceramics, and many others.
