Features:

  • Brown Fused Alumina vs. White Fused Alumina
Item Brown Fused Alumina White Fused Alumina
Smelting Process Produced by melting bauxite, iron filings, and anthracite at high temperatures in an electric arc furnace. Obtained by calcining aluminum oxide at high temperatures, a process that yields a finely uniform crystalline structure, resulting in its white appearance.
Color and Crystal Structure Typically brown in color, this is due to the presence of a small amount of iron elements. Its crystal structure is relatively coarse, containing prism-shaped crystals and brown particles, which endow Brown Fused Alumina with high abrasion resistance. White in color, its crystal structure is relatively fine and uniform, manifested as hexagonal columnar crystals. This gives White Fused Alumina higher hardness and excellent wear resistance.
Hardness and Performance Exhibiting relatively high hardness and wear resistance, it is suitable for general grinding and cutting applications. Its microcrystalline structure also imparts high toughness, aiding in resistance to mechanical impacts. Possessing higher hardness, it is widely used in the preparation of superhard materials and in high-precision grinding. Its particle structure also makes it suitable for applications requiring strict surface smoothness.
Application Mainly used in general grinding, polishing, sandblasting, etc. Its wear resistance and toughness make it perform exceptionally in processing metals, ceramics, glass, and other materials.
  • Extensively utilized in applications demanding high hardness, precision, and smooth surfaces such as grinding, cutting, polishing, and abrasive coatings. It is also used in the production of high-hardness ceramics and electronic components.
