Garnet
The specific gravity of garnet is 3.96g/cm3. The Mohs hardness is higher than 6.0, it is normally 7.0 in fact. The main inner structure of garnet is crystallized iron and alumina. It is suitable for free lapping or being used for making organic bonded abrasive tools. It also has non-abrasive application.
Compared with Artificial aluminum oxide and silicon carbide, garnet is a type of natural abrasive media. It has low cost, so it is widely used for commonly abrasive cutting media.
The normally gritt for abrasive media are: 30#, 36#, 60#, 80#.
SiO2 | Al2O3 | FeO | Fe2O3 |
35.0~42.0 | 20.0~28.0 | 25.0~32.0 | 5.0~10.0 |
30#, 36#, 60#, 80# are the commonly grains. Mohs hardness: 7.0.
