• Details

• We can supply two types fused alumina zirconia, 25% and 40%, can be used for abrasives as F and P grain.
  
  25%
  Extremely wear resistant, our 25% alumina zirconia grains consist of fine primary Corundum and an Alumina-Zirconia eutectic crystalline structure. This structure allows for one of the most durable materials in the abrasives industry, outperforming commodity abrasives like brown fused aluminum oxide and silicon carbide.
  Crystal Size 17 Microns
  True Density 4.3 g/cc
  Vickers Hardness 21 GPA (for 50 gm load)
  Melting Point 1950° C
  Loose Pack Density 1.98 - 2.42 g/cc
  Typical Chemical Analysis
  Aluminum Oxide 75.0%
  Zirconium Oxide 23.0%
  Titanium Oxide 0.10%
  Silica 0.30%
  Iron Oxide 0.30%
  Sodium Oxide 0.08%

  40%
  By controlling the crystal size and microstructure, our 40% alumina zirconia grains reside at the true abrasive eutectic alloy of alumina and zirconia, which creates the extremely fine crystalline microstructure. This structure allows for one of the most durable materials in the abrasives industry, outperforming commodity abrasives like brown fused aluminum oxide and silicon carbide.
