Pink Fused Alumina is also called pink corundum,pink aluminum oxide,pink electrocorundum,chromic fused alumina or chrominum aluminum oxide,it is made from aluminum oxide and chrominum oxide,with high hardness and toughness.
Besides,according to Cr2O3%,Pink fused alumina is divided into low chrominum PFA,medium chrominum PFA and High chrominum PFA.
About bulk density,different size with different cr2o3%,will have different bulk density.now list the bulk density of high chrominum pink fused alumina for reference:
| Grit | Bulk Density(g/cm3) | Grit | Bulk Density(g/cm3) | Grit | Bulk Density(g/cm3) |
| F12 | 1.72-18.2 | F40 | 1.71-1.83 | F100 | 1.49-1.60 |
| F14 | 1.72-1.82 | F46 | 1.73-1.83 | F120 | 1.46-1.60 |
| F16 | 1.72-1.82 | F54 | 1.68-1.75 | 150 | 1.39-1.49 |
