3.50g/cm3 Bulk Density White Fused Alumina 9 Mosh Hardness
Product Description
White Fused Alumina (WFA) is obtained from the fusion of high purity calcined alumina powder in electric arc furnace by melting cooling above
2000℃, after crushing, shaping, deiron and then by screening. It
has high purity, good self-sharpening, acid and alkali resistance,
high temperature thermal stability, low toughness and other
properties. It is slightly harder than brown corundum.
White Fused Alumina, also known as White Fused Aluminium Oxide, is
named for its white color and belongs to the category of fused
artificial corundum. It is an important mineral with chemical and
high temperature stability, high purity, high hardness and good
fire resistance. The abrasives made with it are suitable for manufacturing ceramics,
resin-consolidated abrasives, grinding, polishing, sandblasting,
precision casting (corundum for precision casting), etc.
Application
White Fused Alumina has a white or slightly bluish-gray color, and
its high purity and crystalline structure make it highly resistant
to chemical and physical abrasion. It is used in many applications
including grinding and cut off wheels, refractories and ceramic
shapes, coated abrasives, investment casting shells, laminates,
coatings, blasting abrasives, lapping and polishing, etc. And it
has excellent cutting properties and is ideal for use in grinding,
cutting, grinding, and polishing various materials, including
metals, ceramics, glass, and plastics.
As a result of its hardness (Mohs Hardness>9), White Fused
Alumina is an ideal material for abrasive applications, including
sandblasting, grinding, polishing and coated products. As the
abrasive materials, it is suitable for grinding high-speed, high
carbon steel, as loose grains, it widely used for bonded and coated
abrasives, polishing, precision casting and so on.
White fused alumina is widely used in the manufacturing of
high-performance abrasives, refractories, ceramics, and other
applications that require high levels of purity, hardness, and
durability. Its properties make it an excellent choice for use in
industrial applications such as surface preparation, surface
finishing, and material removal.
