White Fused Aluminum Oxide (WFA) is produced from the melting of high purity calcined alumina in electric arc furnaces. It is characterized by its high hardness, friable, high purity, chemical stability, high melting point and large crystal size.
White cast aluminum oxide is used in many applications, including grinding and cutting wheels, refractory materials and ceramic forms, coated abrasives, investment cast coatings, laminates, coatings, blasting, polishing and lapping abrasives, etc. Please see below for product information related to your request.
1. Bonded abrasive tools.
2. Coated abrasive tools.
3. Refractory and Ceramic.
4. White aluminum oxide obtained from the fusion of calcined alumina in electric arc furnaces. It is recommended for refractory applications where purity, chemical stability, or high refractoriness are a matter to consider.
5. Polishing glass and the electronics industry.
6. Special micro power for precision foundation.
