White corundum is made of industrial alumina powder, which is melted in an electric arc at a temperature of more than 2000 degrees and then cooled. It is crushed and shaped, magnetically separated to remove iron, and sieved into various particle sizes. It has a dense texture, high hardness, and sharp-angled particles. It is suitable for the manufacture of ceramics, resin-bonded abrasives, as well as grinding, polishing, sandblasting, precision casting (special corundum for precision casting), etc. It can also be used to manufacture high-grade refractory materials. The code "WA" is consistent with international general standards and national standards. Most of it is exported, and a certain amount is also supplied to domestic users.

Product Usage

Scope of application: White corundum abrasive is suitable for surface beautification of various high-end products, crafts or hardware products. After sandblasting, the surface is white and free of any impurities, eliminating the trouble of cleaning. Fine white corundum can be used as the first polishing and grinding. It can also be used as an additive for various products. It can be used as solid and coated abrasives, wet or dry or sprayed sand, suitable for super-fine grinding and polishing in the crystal and electronics industries and the manufacture of high-grade refractory materials. It is suitable for processing hardened steel, alloy steel, high-speed steel, high-carbon steel and other materials with higher hardness and tensile strength. It can also be used as a catalyst, insulator and precision casting sand. Rust, dirt and oxide scale removal for iron workpieces, increase the adhesion of plating and coating; oxide scale removal for aluminum workpieces, surface strengthening and polishing; matte effect for copper workpieces, crystal frosting for glass products, engraving patterns; matte effect for plastic products, plush processing and effect patterns for special fabrics such as denim

1. Surface processing: removal of metal oxide layer, carbide black skin, rust removal on metal or non-metal surfaces, such as gravity die-casting molds, removal of oxides or release agents for rubber molds, black spots on ceramic surfaces, removal of uranium color, and rebirth of painted paintings.

2. Beautification processing: matte or matte treatment of various gold, K gold jewelry, precious metal products, matte processing of non-metals such as crystal, glass, corrugated, acrylic, and can make the surface of the processed object metallic luster.

3. Etching processing: etching art of jade, crystal, agate, semi-precious stones, seals, elegant stones, antiques, marble tombstones, ceramics, wood, bamboo pieces, etc.

4. Pre-treatment: Teflon (TEFLON), PU, rubber, plastic coating, rubber roller (ROLLER), electroplating, metal spray welding, titanium plating and other pre-treatment to increase surface adhesion.

5. Burr processing: burr removal of bakelite, plastic, zinc, aluminum die castings, electronic parts, magnetic cores, etc.

6. Stress relief processing: stress relief processing of parts for aerospace, national defense, precision industry, rust removal, paint removal, matting, etc.
