White fused alumina ( WFA )

White Fused Alumina (WFA) is a high-purity synthetic abrasive material produced by melting premium grade aluminum oxide (Al₂O₃) in an electric arc furnace at temperatures exceeding 2000°C. Thanks to its very high alumina content (≥99%), White Fused Alumina is one of the purest and most consistent abrasive materials available on the market.

Compared to Brown Fused Alumina, White Fused Alumina offers higher chemical purity, a more uniform crystalline structure, and superior performance in precision applications.
