    Brown fused alumina oxide of high temperature calcined 1350℃ (Blue fired)

    1. Details

    Brown fused alumina oxide of high temperature calcined 1350℃ (Blue fired)

    CODE: BC-BFA -HC1350

    Brown fused alumina shows blue after calcination at 1350℃ temperature. The impurities existed in the grains will be separated out & vaporized . The surface of each particle changes coarser, improves the hydrophilicity greatly. After 1350℃ calcinations ,cracks from crushing and crystal cooling process be closed ,the toughness,strength is some better than normal BFA and enhancing the wear resistance too.

    This product is mainly used for high speed strong belt, High grade bonded abrasive, resin wheel ,sand paper, tray ,large cutting disc, and can also be used to grind stainless steel plate, alloy steel and cemented carbide .
