Pre-Cast Shapes

Mighty Fibre B-AL-310

Mighty Fibre B-AL is a precast shape made with a high alumina, cement-bonded castable with metallic fiber composite for added strength and spalling resistance. Mighty Fibre B-AL precast shapes are used in aluminum furnace applications where mechanical abuse and thermal cycling are normal operating conditions, such as door jambs and sills on aluminum melting furnaces.
