White Fused Alumina
White Fused Alumina (WFA), also known as white aluminum oxide or white corundum, is produced from high-purity, low-sodium alumina powder after high-temperature melting, cooling, crystallization, and crushing. It is a particle with tightly controlled particle size distribution and consistent appearance.Performance: White, with more than 99% α-type crystals, high purity, high hardness and high toughness, strong cutting force, good chemical stability, good insulation.
XINLI Abrasives supplies white fused alumina in grit and powder forms for industrial surface preparation, abrasive tool manufacturing, grinding and polishing applications. We can help buyers select a suitable grade according to the workpiece material, required surface finish and processing method.

FAQ
What is white fused alumina used for?
It is used in selected sandblasting, abrasive tool manufacturing, grinding, polishing and refractory applications. The appropriate grade depends on the process and required finish.
What is the difference between white fused alumina grit and powder?
Grit generally refers to coarser abrasive grains, while powder refers to finer particles used in applications that require smaller particle sizes. The exact size ranges depend on the applicable grading system and supplier specification.
How do I select the right particle size?
Start with your processing method, workpiece material and required surface finish. Share your target grit designation or particle size with the supplier, and test the selected grade before full-scale use.
Is white fused alumina harder than brown fused alumina?
White fused alumina generally has higher hardness, while brown fused alumina is generally tougher. Selection should depend on the application and the balance of cutting performance, toughness and service life required.
Can I request a sample?
