Product Description

Brown Corundum with good hardness grit for marine hull cleaning and architectural restoration

 

Brown Corundum / Brown Fused Alumina /Brown Fused Aluminum Oxide/ Brown Aluminum Oxide

Description:
Brown fused alumina is made of high-quality bauxite as raw material, anthracite and iron filings. It is made by arc smelting at 2000°C or higher temperature. It is crushed and plasticized by self-grinding machine, magnetically selected to remove iron, sieved into various sizes, and its texture is dense and hard. High, spherical pellets, suitable for the production of ceramic, high-resistance abrasive resin and grinding, polishing, sandblasting, precision casting, etc., can also be used to manufacture high-grade refractories.

Brown fused aluminum oxide is a tough, hard material (Mohs hardness 9) with high strength, excellent wear and corrosion resistance and good thermal conductivity.

 

Advantages of Aluminum Oxide

Wide range of grades available for different jobs and profiles (65% al2o3~96.0%al2o3)

  • Non-reactant – will not interfere with your coatings
  • The high percentage of TiO2 (1-4%) shows the toughness of the product, which results in longer cutting life, more circulations before breaking down and increased cost effectiveness
  • No detectable “crystalline silica”
  • Environmentally friendly
