CH Refractories' high alumina fire brick is a perfect choice for applications requiring extreme heat resistance. Its high alumina content and superior thermal conductivity make it ideal for use in high-temperature furnaces, kilns, and other industrial and commercial processes. The brick's excellent thermal conductivity and low linear change rate helps to ensure consistent performance in even the most extreme conditions. The low bulk density and high cold crushing strength make it highly durable and resistant to thermal shock. Its refractoriness is up to 1790℃, making it a perfect choice for applications requiring high heat resistance.

Model numbers CHAH45~85 and SK35~SK40 are perfect for any application requiring high heat fire bricks, high alumina refractory bricks, or fire refractory bricks. With its ISO origin, it is an ideal choice for high-temperature industrial and commercial applications. Its thermal conductivity is ≤0.7W/m.K, its linear change rate ≤0.2%, its bulk density ≥2.2g/cm3, and its cold crushing strength ≥50MPa. All of these features make it an ideal choice for applications that require top-of-the-line performance.
