White Fused Alumina (WFA) is a high-purity, white abrasive made from aluminum oxide. It is produced by melting high-quality alumina in an electric arc furnace at very high temperatures. During the melting process, impurities are removed, resulting in a clean and crystalline alumina. The resulting grains are crushed and classified to produce different grains of White Fused Alumina.
