Description:
WFA is produced form the fusion of high purity calcined alumina in electric arc furnaces.
It is characterized with high hardness, yet friable, high purity, chemical stability, high melting point, and large crystal size WFA is used in many applications includes: grinding and cut off wheels, refractories, and ceramic shapes, coated abrasv=ives, lapping and polishing, and etc.
Application:
- Bonded Abrasives Tools
- Coated Abrasive Tools
- Refractories & Ceramics
- Polishing Crystal & Electronic Industry
- Special Micropowder for Precision Founding
