Brown Fused Alumina

  • BTUS

    Crushed and sized in the USA. Due to its high toughness, BTUS is recommended for use in grinding wheels, cutoff wheels, points, blasting abrasives, etc...

  • BT - R

    Due to its high toughness, is recommended for high performance grinding wheels.

  • BTCAL - R

    BTCAL is heat treated in a rotary kiln at high temperatures and magnetic treated. These procedures guarantee low iron content and high toughness. BTCAL is recommended for high performance grinding wheels.

  • MAXCAL - R (Low Titania BFA)

    MAXCAL is a special brown fused aluminum oxide developed for high performance abrasive products. MAXCAL is low titania content product, heat treated in a rotary kiln at high temperatures and magnetic treated. These procedures guarantee low iron content and excellent grit stability.

  • MAXCAL - R (Low Titania BFA)

    MAXCAL is a special brown fused aluminum oxide developed for high performance abrasive products. MAXCAL is low titania content product, heat treated in a rotary kiln at high temperatures and magnetic treated. These procedures guarantee low iron content and excellent grit stability.

  • ALOMAX - R (Semi-Friable BFA)

    ALOMAX is a semi friable brown fused aluminum oxide that presents good toughness and excellent abrasion properties and is recommended for high performance bonded abrasives.

  • SFAR- R (Semi-Friable BFA)

    SFAR is a semi-friable brown fused aluminum oxide. In order to improve its quality, this material is calcined and presents low dust content. It is recommended for high performance bonded abrasives.

  • SFARBF- R (Semi-Friable BFA)

    SFARBF is a semi-friable brown fused aluminum oxide. SFARBF is heat treated in high temperatures and these procedures guarantee stress relief and high toughness. SFARBF is recommended for high performance grinding wheels.
