Descriptions:
Green Silicon Carbide is mainly made of Quartz sand, petroleum coke, smelted by above2500°C in the electric furnace. The hardness is between corundum and diamond. The Hardness is superior to corundum, it has the function of conductivity and thermal conductivity. It is suitable to process metals and non-metallic materials, such as gray cast iron, non-ferrous metal, stone, leather, rubber, and on on.
We offer all grades, many of which are available for purchase online in small quantities.
