Product Description

High Toughness 99% AL2O3 Fused Aluminium Oxide F12-F220 for Sandblasting Media


1. Product Description of Fused Aluminium Oxide White (White Fused Alumina) 

Fused Aluminium Oxide White is also called as white fused alumina(WA),it is selected the industrial alumina

powder as raw material,then smelting in an electric arc under high temperature over 2000 degrees, then

made into different grit through the process of cooling,crushing,magnetic separation etc.

It is widely used as one blasting media where requires minium foregin contamination.

3. Main Product Features of Fused Aluminium Oxide (White Fused Alumina)

High Purity

The fused aluminium oxide has a high purity, which contains over 99.2% Al2O3, then there is no contamination

to the blasting treatment, and also one ideal abrasive for blasting ferrous-free materials.


High Hardness

Fused Aluminium Oxide white is a hard abrasives,whose Mohs hardness is 9, its angular shape and high

hardness makes it more aggressive in high speed blasting process,then it is more easy to achieve the

expected blasting effect.


High Toughness

Its superior toughness also allows it an recyclable materials,it could be reused multiple time.

Ecological Abrasive


Fused aluminium oxide white is an ecological abrasive,it is no harmful impact on human health and the



4. Main Application of Fused Aluminium Oxide White in Sandblasting

  • To blast ferrous-free materials such as stainless steel food tanks,carbon steel, cooper etc.
  • Removing Corrosion and Surface Deposits
  • Precision blasting of medical components
  • Etching and Decorating such as the blasting for various craft glass
  • Beautify processing to achieve the matting or matte treatment for all kinds of gold, precious metal products
  • Surface Prep for Thermal spray coatings
  • Removing the oxide Scale such as the casting molds,tire molds,shoe mould etc.
  • Precision blasting for aviation stress relief such as turbine.

In addition, it is also widely used in the following applications of


Bonded brasives such as resin cutting discs,grinding wheels etc.;


Coated abrasives: abrasive belts, abrasive sheets etc.;


Grinding,polishing and lapping media.


High grade refractories.
