Introduction to high alumina refractory bricks

High alumina brick is a neutral refractory material with an alumina content of more than 48%. It is formed and calcined from bauxite or other raw materials with high alumina content. High thermal stability, fire resistance temperature above 1770℃.

Our high alumina brick raw materials

Our company only sources high-quality raw materials from long-term, trustworthy suppliers. All raw materials entering the factory are strictly inspected. Each production process will be strictly controlled to ensure quality and consistency to provide customers with the highest quality high alumina bricks.
