White Fused Alumina grain with Al2O3 99.2 min
ISO9001 Certificated
Strong wear and heat resistance
1. Advantage
White fused alumina is made of quality alumina powder by smelting at 2050 °C.
1). High purity
2). Good self-sharpening
3). Less thermal diffusivity in grinding
4). Strong acid-alkali resistance
5).Excellent high-temperature stability,
6). Low porosity, etc
