High Alumina Bricks

High Alumina Bricks are manufactured using high-quality bauxite, alumina, and selected raw materials to deliver exceptional resistance to high temperature, corrosion, abrasion, and thermal shock. These bricks are designed for use in industrial furnaces, boilers, rotary kilns, and all high-temperature process units.

High Alumina Bricks from OM SAI REFRACTORIES are engineered with advanced technology to deliver a high melting point, superior structural strength, and excellent load-bearing capacity at elevated temperatures. Their low porosity and high density make them highly durable in areas exposed to molten slag, chemical fumes, abrasion, and mechanical impact.

Available in 40% to 90% alumina content and standard as well as custom shapes, these bricks are suitable for a wide range of industrial applications.
