Silicon carbide is a non-metallic mineral product produced by quartz sand (SIO2) and petroleum coke (C) and sodium chloride (NaCl) as basic raw materials under high temperature conditions above 1800 degrees Celsius, and two kinds of silicon carbide, Black SiC and Green SiC , are formed depending on the production materials. It has high hardness, small expansion coefficient, brittle, good thermal conductivity and other characteristics.
So what are the grit sizes for silicon carbide abrasive production? Today Henan Superior Abrasives silicon carbide manufacturers to introduce the detailed silicon carbide abrasive production particle size.
Henan Superior Abrasives silicon carbide production executive standards are Chinese standards, European standards (FEPA), Japanese standards (JIS). The international code of black silicon carbide grit is:C, and the international code of green silicon carbide grit is:GC.
Henan Superior Abrasives produces the following European standard (FEPA) product models:
F6#, F8#, F10#, F12#, F16#, F20#, F22#, F24#, F30#, F36#, F40#, F46#, F54#, F60#, F70#, F80#, F9O#, F100#, F120#, F150#, F180#, F220#, F240#.
