WHITE FUSED ALUMINA FOR SANDBLASTING
White aluminum oxide, also called White fused alumina , white corundum etc., is electrically fused in arc furnace with high-grade aluminum oxide powder as raw material, then made into different grain size by crushing and reshaping, magnetic separation, and screening. Compared with brown aluminum oxide, it is with higher hardness and slight lower toughness. It also has features of high purity, good self-sharpening, high cutting efficiency, less heat emit, acid and alkali resistance, good thermal stability, etc.. Widely used for bonded and coated abrasive, polishing, sandblasting, precision casting, refractory etc...

FEATURES IN SANDBLASTING
The advantages of white aluminum oxide
1. High hardness, dense particles and good circularity of single particles.
2. The color is pure white, no impurities, ensuring the color and transparency of the wear layer.
3. The particle size distribution is evenly concentrated, the single particle shape is consistent, and the minimum wear resistance can be achieved with the minimum amount.
4. Chemical properties are stable and acid and alkali resistance , and the heat shrinkage is extremely small.
