Alumina fire bricks from Astha Export are refractory ceramic blocks composed of 50% to 99% aluminum oxide (Al2O3), engineered for extreme thermal environments. The bricks are formed from fire clay and refractory composites, sized for single-handed masonry installation with mortar, and designed to withstand sustained exposure to high temperatures without structural degradation.
These bricks exhibit superior resistance to thermal shock, maintaining dimensional stability and load-bearing strength even under rapid temperature fluctuations typical in steelmaking, cement kilns, and petrochemical processing. Standard industry grades for alumina fire bricks often include classifications by Al2O3 content, with higher percentages offering increased corrosion resistance to slag and molten metal. Typical porosities range between 18% and 25%, balancing insulation properties with mechanical integrity.
Primary applications include lining furnaces, kilns, fireboxes, and fireplaces in industries requiring consistent heat retention and durability. Industrial buyers source these bricks under HS code 6902.20, with India being a major producer alongside China and Brazil. The bricks are traded internationally in metric-ton quantities, with packaging and lead times tailored to bulk industrial orders.

Before placing an order, verify the exact Al2O3 grade and physical dimensions of the bricks to ensure compatibility with your furnace or kiln specifications. Request a certificate of analysis for the batch, confirming Al2O3 content, porosity, and density, as these directly impact performance in high-temperature applications.
Confirm logistics details such as packaging type, palletization, and loading constraints for bulk shipments from Vadodara, Gujarat. Lead times can vary based on production schedules, so clarify whether the supplier operates on a make-to-order or stock basis. Incoterms such as FOB or CFR should be agreed upon, with payment terms aligned to standard industrial practices for refractory materials.
Conduct quality checks upon receipt, including visual inspection for cracks or deformities and dimensional verification against tolerances. For critical applications, arrange third-party testing for thermal shock resistance and corrosion performance. Ensure all documentation, including HS code 6902.20 and material safety data sheets, accompanies the shipment for customs and compliance purposes.
