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.
