Product Description

 

Product Description

White Fused Alumina Powder

White fused alumina abrasive powder produced by crushing fused alumina and sorting the particles into a uniform size. The resulting compound has the following characteristics:
An α type corundum crystal configuration
At least a 99.0% pure aluminum oxide (Al2O3) composition
A hardness nearly equal to silicon carbide
A closely controlled particle-size distribution
A consistent particle shape
These characteristics make WFA a superb choice for high-level surface polishing and as a material in items such as: Super-finishing precision grindstones Super-finishing lapping cloth or paper Lapping tape for super-precision surface finishing Precision lapping of materials such as metals, quartz crystal, and semiconductor having low tensile strength
