Colour:

Blue

Phase:

α-Al₂O₃

Hardness:

2100 kg/mm²@50 gm

Shape:

Blocky

Applications:

Semi-friable grains undergo blue heat treatment to enhance toughness, improving durability and performance for use in thin wheels, snagging wheels and roll grinding wheel applications.

Product Features:

Enhanced Toughness: Blue heat-treated semi-friable grains resist breakage for longer life.

Higher Efficiency: Improved Grinding Rate (GR) and Material Removal Rate (MRR) boost productivity.

Versatile Application: Ideal for Thin wheels, Snagging Wheels and Roll grinding Wheels.

Blue Fired Semi-Friable Alumina is a specially heat-treated grain manufactured under a closely controlled process. The heat treatment induces a structural blue phase, imparting maximum toughness and durability. The product is particularly suitable for aggressive cool-cutting applications and is ideal for heat-sensitive steels, metals and alloys.
