White Fused Alumina

High-purity aluminum oxide for precision grinding, polishing, and refractory applications

What is White Fused Alumina?

White Fused Alumina (WFA), also known as white aluminum oxide, is a high-purity synthetic abrasive produced by melting high-quality alumina in an electric arc furnace. With aluminum oxide content above 99%, it is free of iron and other impurities, making it ideal for precision grinding and high-end refractory materials.

Its hardness, sharp edges, and high chemical resistance make WFA widely used in surface preparation, blasting, polishing, and technical ceramics.

Features & Properties

  • Al₂O₃ purity ≥ 99.3%
  • High hardness (Mohs 9.0), excellent wear resistance
  • Iron-free, low magnetic content
  • Sharp angular particles for effective cutting
  • Thermally stable and chemically inert

Applications of White Fused Alumina

  • Abrasives: grinding wheels, polishing compounds, coated abrasives
  • Refractories: castables, bricks, kiln furniture
  • Surface treatment: sandblasting for stainless steel, aluminum, glass
  • Technical ceramics: substrates, electronic insulators
  • Precision components: aerospace, semiconductor polishing
