White corundum (WA) is manufactured from Alumina powder by crystal electro-fusion process at high temperature of over ***0C.
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.
