US Electrofused Minerals offers a wide range of products in various particle shapes, particle sizes and density to meet all of your requirements.

Products for Bonded Abrasives include:

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.

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.

TB - R (Friable BFA)

TB is a friable brown fused aluminum oxide. TB presents an excellent cost/benefit relation, being recommended for resin-bonded abrasives and cut-off wheels.

White Fused Alumina

AL - R

AL - R, a white fused aluminum oxide, presents high purity and high capacity of edge reposition. AL - R is recommended for special applications where contamination is an issue to be considered.

Pink Fused Alumina

RU - R

RU - R is a pink aluminum oxide obtained by fusion of calcined alumina and chrome ore in electric arc furnaces. Its high purity and self-edged reposition characteristic makes RU a special product for vitrified grinding wheels.

Ruby Fused Alumina

RUHC - R

RUHC - R is a dark pink aluminum oxide obtained by fusion of calcined alumina and chrome ore in electric arc furnaces. Its high purity and self-edged reposition characteristics make RUHC a special product for vitrified grinding wheels.
