White Fused Alumina Oxide has white color and a little higher hardness and thoughness comparing with the brown one. The grinding tools made of this material are suitable for fine grinding of high carbon steel, high-speed steel and stainless steel, abrasive powder of finer grit size, can also be used for precision casting and high-grade refractory.
