Product Details

Product name: Good toughness White corundum for Jeans sanding

Product Picture:

Introduction:

White corundum (WA) is manufactured from Alumina powder by crystal electro-fusion process at high temperature of over 2000C.

Its hardness is a little higher and toughness is a little lower than brown corundum.

It has the advantages of high purity, good sharpness, strong grinding force, less calorific value, high efficiency, good acid/alkaline corrosion resistance, high temperature resistance, good thermal stability, etc.

Applications:

It has been widely used to make bonded and coated abrasive tools for grinding carbon steel, alloy steel ;as materials of super precision grinding and polishing, high quality refractory, precision casting; materials of carrier of chemical catalytic agent and specialized ceramics; to atomize glass or acrylic arts.

1. for precision casting and high-grade refractory.

2. for bake lining, Catalyst carrier, friction products

3. for pressure blasting hard abrasives; Refractory industry

4. for wet and dry blasting, grinding, lapping and polishing media

5. for abrasive tools: grinding wheel, Lapping and polishing non-skid title;

6. for bonded and coated abrasives, Thermal Spraying (Plasma Spraying)

7. for lapping & Micro-Blasting applications .refractories, Ceramics and Tiles.
