High TiO2 3.0%Min White Fused Alumina Gain F12 F30 F80 For Vitrified Wheel.White Fused Aluminum Oxide Grit F24 F30 F36 for Vitrified Wheel. White fused alumina electrically fused in arc furnace with high grade processed alumina as raw material. It has higher hardness and slight lower toughness comparing with brown fused alumina. It is also characterized by its high purity, ability of self-sharpening, better cutting, less heat emit, higher efficiency.
White fused aluminum oxide becomes the first choice for the sandblasting , meanwhile, it is also the ideal material for abrasive and work piece cleaning, and polishing.
Comparing with brown fused alumina, white aluminum oxide is also characterized by its high purity, acid and alkali resistance, good thermal stability. It’s the high grade refractory materials.
White fused alumina for abrasive , sandblasting ,Precision casting advantages:
1,Available research in a variety of blasting and light lapping operations
2,The process of beautifying glass or acrylic
3,The process of blasting TV screens
4,The cutting of silicon wafer
5,The process of cleaning and blasting tooth model
6,Precision sand casting
7, High refractory and other ceramic additives
