White Fused Alumina
White fused alumina (WFA) is produced by melting high-quality alumina powder in an electric arc furnace at temperatures above 2000°C. It features high purity, high hardness, excellent self-sharpening ability, and strong resistance to acid, alkali, and high temperatures. WFA is widely used in ceramics, refractory materials, abrasives, and other industrial applications requiring stable and durable performance.
