White Fused Alumina (WFA) is a synthetic crystalline material made from high-purity aluminum oxide. It is produced by fusing alumina in an electric arc furnace at high temperatures. The result is a hard, tough material with excellent chemical resistance and a high melting point.
It is a kind of raw material characterized with high hardness, friable with high purity, chemical stability, a high melting point, and large crystal size.
The final product is a purer aluminum oxide that can be used in a specialty process without losing any of the strength and sharpness of brown fused alumina.
Grinding & Cutting Tools – Perfect for producing high-precision grinding wheels.
Surface Preparation – Excellent for fine blasting and delicate cleaning tasks.
Polishing & Finishing – Provides smooth, clean finishes for high-end surfaces.
Refractory Materials – Suitable for manufacturing heat-resistant and corrosion-resistant products.
