Material Notes:

Cordierites have low coefficients of thermal expansion and excellent resistance to thermal shock. They offer a range of thermal expansion, mechanical strength, and porosity criteria. They excel as cost-effective extruded and dry-pressed forms. 447 offers excellent thermal shock resistance with high continuous porosity, suitable for applications such as welding tile.
