IFB-26 is the 57.3% Al₂O₃ grade in our insulating fire bricks range, rated to 1400°C. Typical catalogue values: Al₂O₃ content 57.3%; bulk density 0.86 g/cc; thermal conductivity 0.23 W/mK; cold crushing strength 1.8 MPa; max service temperature 1400°C. It is also referred to as CUMILAG 26. Confirm the exact figures on the grade datasheet before specifying.

IFB-26 carries 57.3% Al₂O₃.

Applications for the insulating fire bricks range include high-temperature kiln hot face & backup lining (ceramic, metallurgical), general backup insulation behind a dense working lining, primary reformer & hydrogen transfer line backup (fertiliser, petrochemical), secondary reformer cold face, blast furnace stoves, high-temperature air pre-heaters (power generation) and heat treatment furnace linings & soaking pits backup. Grade selection depends on your operating conditions; send them to us and we will confirm IFB-26 or a neighbouring grade.

IFB-23: 37.2% Al₂O₃, rated to 1260°C. IFB-26: 57.3% Al₂O₃, rated to 1400°C. IFB-28: 67.2% Al₂O₃, rated to 1540°C. Higher alumina generally brings higher refractoriness and slag resistance. Send us your application and operating temperature and we will confirm the grade.
