It is a kind of regular Brown Aluminum Oxide abrasive grains, the shape of the grain is blocky and edge sharp with the high loose bulk density. To get the kind of grains, we specially process the
ingots, separate the magnetic material, and sieve the grains carefully to get a complete range of grit sizes. Typical Chemical Analysis Al2O3 Fe2O3 TiO2 SiO2 CaO 95.70% 0.12% 2.66% 0.98% 0.22%
Physical Properties Color Dark brown Shape Blocky, tough and sharp Crystal Form Alpha-alumina trigonal system True Specific Gravity 3.96 g/cm3 Hardness 2090 Knoop scale; 9.0 Mohs scale Melting
Temperature About 2050
