CORALEX

Description

CORALEX fire bricks have the highest alumina content in our portfolio—up to 95%. They are dedicated to applications at temperatures up to 1700 °C and in the most challenging working conditions of the lining.

The proper selection of refractory material for a specific application requires an appropriate analysis of the device's operating conditions. Before choosing the type of material, contact our specialist to confirm its suitability for your furnace.
