Colour:

Blue

Phase:

α-Al₂O₃

Hardness:

2150 kg/mm²@100 gm

Shape:

Angular with sharp edges

Applications:

Semi-friable grains are subjected to a blue heat treatment to enhance toughness. This process boosts durability and performance, making them well-suited for rolls, sheets, discs, and various coated 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 rolls, sheets, discs, and other coated products.

Blue Fired Semi-Friable Alumina is a specially heat-treated grain manufactured through a closely controlled process. The heat treatment develops a structural blue phase, imparting maximum toughness and durability. This product is especially suitable for aggressive, cool-cutting applications.
