F46 WFA powder white fused alumina
Deion about white fused
alumina :
White corundum(WA) is manufactured from Aluminia powder by crystal
electro-fusion process at high termperature of over 2000C.Its hardness is a
little higher and toughness is a little lower than brown corundum.It has the
advantages of high purity, good sharpness, strong grinding force, less
calorific value, high efficiency, good acid/alkaline corrosion resistance,high
temperature resistance, good thermal stability, etc.

Applications
- 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.
