Product Description
White Aluminium Oxide/white fused alumina
White Aluminium Oxide is made by Aluminium Oxide powder which is electrically fused at high temperature. It is white. Compared with Brown Aluminium Oxide, its hardness is a little higher, but its toughness is little lower. Our WA has the features of stable quality, well-distributed particle size composition, low magnetic substance content, high bulk density and hardness, good toughness, and high cleanliness, etc. It has been exported to more than 20 countries in Europe, America, Southeast Asia, etc. The abrasive tools made by WA are suitable for grinding high-carbon steel, high-speed steel and chilled steel, etc. In addition, it can be also used for polishing materials, precision casting sand, spraying materials, chemical catalyst carrier, special ceramics and high-grade refractories, etc.
As coating abrasive grains, White Aluminium Oxide features very strong anti-erosion and grinding ability. Because its grains are sharpened and multangular, there is no clogging situation when grinding. It is suitable for sanding all kinds of soft material, such as wood, plastic, etc. The White Aluminium Oxide also has excellent character in static electricity fields.
