Appearance: fused alumina grain/powder
Color: white
Ab.: WFA
Features:
White aluminum oxide (WFA) has white color and a litter 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.
