White Fused Alumina
White Fused alumina is smelting in a electrical arc furnace from aluminum oxide powder. The color is white, the hardness and toughness is a little higher than brown aluminum oxide. The grinding tools made of it are suitable for fine grinding of high carbon steel, stainless steel and high speed steel. The fine frit size and powder of these materials are also used for precision casting and high grade refractory.
TYPE WAE-17M
This kind of white fused aluminium oxide grain has sharp shape and medium bulk density, can be used for different grinding abrasives applications.
Size Distribution: According to FEPA-Standard 42-1984 R 1993
