White fused alumina for abrasives and refractory
White corundum is an artificial corundum abrasive, the main component of aluminum oxide (Al2O3), and contains a small amount of iron oxide, silicon oxide, etc., the color was white. White corundum high quality alumina powder as raw material, refined crystalline and fused into, there are dense texture, high hardness, high temperature, acid corrosion, thermal stability properties. particles cusp form for use in the manufacture of ceramics, resin bonded abrasives and grinding, polishing, blasting, precision casting, can also be used to manufacture advanced refractory.

Advantages of white corundum
1. Does not affect the color of the work piece
2. Processing speed, high-quality fast
3. Micronized ideal for wet blasting and polished work
4. Can be used in the production of non-iron residual process
Using of white corundum
1. Finish: metal or non-metallic surface dirt rust clear
2. Beautification process: a variety of matting or matte gold, K gold jewelry, precious metal products of processing
3. The etching process: jade, crystal, agate, seals, marble gravestone, ceramic, wood, bamboo and other artists of the etching.
4. Pre-treatment process: PU, rubber, plastic coating, plating, spray welding, titanium, etc. prior to treatment, to increase surface adhesion.
5. Burr processing: plastic, zinc and aluminum die-casting products, electronic components, such as the removal of the core.
