Dynamic Thermal & Mechanical Management

The graphite content in these alumina magnesia carbon bricks enhances thermal conductivity, preventing stress accumulation during temperature fluctuations. Meanwhile, the magnesia-alumina bond maintains structural integrity during thermal cycling.

Enhanced Oxidation and Corrosion Resistance

Proprietary antioxidants such as metallic Al, Si, and B compounds shield the bricks from oxygen degradation. This makes our magnesia alumina brick products ideal for use in oxidizing atmospheres like those found in BOFs and ladle refining units.

Low Porosity for Long-Term Durability

Each magnesia alumina carbon brick exhibits ≤5% apparent porosity, ensuring protection against slag and molten metal infiltration. The dense microstructure supports longer service life and reduced downtime.

Tailored Formulations and Sizes

As a leading magnesia alumina carbon brick supplier, Laurel provides customizable dimensions and chemistry to suit unique furnace geometries and processing environments.
