| White fused alumina (WFA/WA/A) is a raw material for production of refractories material. It also called white corundum or white aluminum oxide. The result is a product with high hardness, high friability, high purity, high melting point, and large crystal size. It widely used in refractory industry, also can be used in ceramics shapes grinding wheels, sandpaper, blasting media, metal preparation, laminates coatings, lapping, polishing, grinding and hundreds of other applications. |
Common section sand: 0-1mm 1-3mm 3-5mm 5-8mm
Commonly used abrasive particle size sand, fine powder: 30 # 46 # 60 # 80 # 100 # 150 # 180 # 200 # 325#
Common micro powder for polishing and grinding: 400 # 600 # 800 # 1000 # 1500 # 2000 # 4000 # 8000#
The application fields of white corundum are very extensive, with the most common application being in
grinding and grinding tools. White alumina has extremely high hardness and wear resistance, making it suitable for manufacturing
grinding wheels, cutting tools, and grinding tools. It is also widely used in a
viation, military, and aerospace fields, such as manufacturing engine parts, missile parts, ballistic shields, and bulletproof glass.
White corundum is also used in
the manufacturing of electronic components and semiconductor devices. It has excellent insulation performance and chemical inertness, playing an important role in power and electronic applications.
White corundum also has extensive applications in the
medical field, such as
artificial joints, dental restoration, and surgical instruments.
In addition, white alumina is widely used in the
chemical industry, such as in the production of
catalysts, chemical containers, and anti-corrosion materials
It is also used to manufacture advanced ceramic products, such as tableware, artworks, and building materials.
