Descriptions
Green Silicon Carbide is an extremely hard (Knoop 2600 or Mohs 9.4) man made mineral that possesses high thermal conductivity (100 W/m-K). It also has high strength at elevated temperatures (at 1000°C, Green SiC is 7.5 times stronger than Al2O3). Green SiC has a modulus of elasticity of 410 GPa, with no decrease in strength up to 1600°C, and it does not melt at normal pressures but instead dissociates at 2815.5°C.
HIJO Abrasives offers a whole range of macro and micro grits in green silicon carbide, quality and various particle size distributions based on FEPA, and JIS standards.
Silicon Carbide is used as a cutting medium due to its extreme toughness and hardness. It is superior to any other abrasive in its ability to penetrate and cut faster under light pressure.
A typical example is a cut-off wheel used to cut titanium, stone, concrete, tiles, ceramic, glass, plastic and PVC.
