Calcined Brown Aluminum Oxide

After calcinations at a certain temperature according to different grit numbers and subsequent processing, the organic matters inherent in the abrasives will vaporize and the abrasive will have higher purity, cleanliness, stronger hydrophilicity, smaller expansion coefficient, higher toughness, lower content of magnetic material and higher strength.

Typical Chemical analysis in wt.% (F24):
Index Al2O3 SiO2 Fe2O3 TiO2
Typical value 95.46 0.76 0.14 2.69
Grits available:
