Microgrit WA is raw material characterized with high hardness, yet friable with high purity, chemical stability, a high melting point, and large crystal size. Each Microgrit WA particle is a discrete crystal of aluminum oxide having a purity of over 99%.
It is used in many applications including
- grinding and cut off wheels
- coated abrasives
- laminates
- coatings
- blasting
- lapping and polishing
