Brown Fused Alumina

 


Description:

Aluminum Oxide is manufactured in an electric arc furnace that produces an extremely tough, long-lasting grain which is graded to exacting standards. The various macrogrit sizes may be used for all types of bonded abrasive and general industrial applications.

Applications:

It is particularly useful for rough grinding, deburring, snagging and cutting of low-alloy, ferrous materials. Silane coating to improve wet strength in resin wheels is available. Iron Oxide (red coat) is available to increase bonding strength.

Aluminum Oxide (Al2O3) 96.13%
Titanium Dioxide (TiO2) 2.21%
Silicon Dioxide (SiO2) 1.03%
Iron Oxide (Fe2O3) 0.22%
Others (MgO, CaO, Cr2O3) 0.41%
