Features: White Aluminum Oxide has white colour and a little higher hardness and toughness comparing with the brown one.
Application: The grinding tools made of this material are suitable for fine grinding of higher carbon steel, high-speed steel and stainless steel. Abrasive powder of finer grit sizes can also be used for precision casting and high-grade refractory materials.
