- For Blasting
Model：Material: Nonmetal Shape: Angular Hardness: Hard
Abrasive material of higher purity, containing less impurities like iron, to have higher hardness than Brown Alumina.
Main Features of White Alumina
・Made by pulverization of high-purity aluminum oxide (alumina) refined by the Bayer process.
・White color because no Titanium (Ti) contained.
・An abrasive material suitable for grinding of steel material of high hardness.
・Also suitable for pretreatment before thermal spraying.
