Du-Co Ceramics manufactures cordierite ceramic components for applications requiring exceptional thermal shock resistance, good electrical insulation, and dependable high-temperature performance. Cordierite, also known as magnesium aluminosilicate ceramic, is a low-cost technical ceramic material that combines good mechanical strength, wear resistance, and low thermal expansion, making it ideal for applications exposed to rapid temperature changes and repeated heating and cooling cycles. Cordierite ceramic components are commonly used in electric heating equipment, thermocouple assemblies, welding applications, and industrial processing equipment.
