Microgrit WA Series

White Fused Aluminum Oxide

Microgrit WA is an aluminum oxide powder re-introduced by Micro Abrasives Corporation in 2001. Microgrit WA is a white fused blocky shaped aluminum oxide with a very clean surface. Each Microgrit WA particle is a discrete crystal of aluminum oxide having a purity of over 99%.

White Fused Alumina is obtained from the fusion of high purity calcined alumina in electric arc furnaces. WFA is raw material characterized with high hardness, yet friable with high purity, chemical stability, a high melting point, and large crystal size.

White Fused Alumina is used in many applications including grinding and cut off wheels, refractories and ceramic shapes, coated abrasives, investment casting shells, laminates, coatings, blasting abrasives, lapping and polishing, and many, many more.

Micro Abrasives Corporation has been the market leader in supplying “clarity enhanced” aluminum oxides for the laminate industry since 1972. Our “S” treatment gives an ultra-clear glass like finish to any laminate surface.

• Can use lower grams/m2 of Al2O3 to melamine or lacquer
• Higher tabor results
• Improved clarity
• Less aluminum oxide pull-out

Micro Abrasives Corporation offers a variety of different suspension treatments to prevent hard packing and provide different levels of suspension. Custom blends of treatments can be made for special or unique customer applications.
