Corundum Introduction
Corundum is high-quality alumina powder as raw material, refined and crystallized fused, slightly higher than the corundum hardness, toughness slightly lower, high purity, good self-sharpening, grinding ability, heat a small, high efficiency, acid corrosion, high temperature thermal stability. Made with its abrasive for grinding high-speed steel, high carbon steel, widely used in bonded abrasives, coated abrasives, polishing and precision casting and other industries. And since the corundum crystals formed by the fused refining, slightly higher than the corundum hardness, toughness slightly lower, high purity, acid corrosion, high temperature thermal stability, is an advanced refractories.
Corundum Features
1, does not affect the color of the workpiece;
2, can be used to blast the remaining non-iron manufacturing process;
3, micronized ideal for wet blasting and polished work;
4, processing speed and high quality;
5, the amount of iron oxide contained in low iron suitable for sandblasting residues of prohibited jobs;
6, after pickling step to remove impurities.

Corundum Uses
Corundum for a variety of other high-end products, processes or hardware products to beautify the surface treatment, surface clean and without any impurities after sandblasting, replacing cleaning trouble. Fine white fused alumina can be used as the first polishing abrasives. It can also be used to make a variety of products additives.
1. Available in a variety of sandblasted and polished (lTbppinTb) job
2. atomized glass or acrylic art of aesthetic processing
3. The TV screen in the sandblasting process
4. The cutting element of silicon
5. Clean sand mold of the tooth
6. precision casting sand
7. burr processing: flash Bakelite, plastic, zinc, aluminum die-casting products, electronic components, core, etc. removed. Elimination of processing power.
