Automotive manufacturing industry relies on the superior performance of high-performance ceramic components to create significant lifetime advantages and process reliability in mechanical and plant engineering. The abrasion resistance, impact resistance and bending strength of engineering ceramics greatly reduce manufacturing costs. Ceramic parts are widely utilied in automotive manufacturing industry, such as pins and nozzles for welding, centering sleeve, etc. Ceramics are used as auto parts mainly because their properties of lightweight, high temperature resistance, insulating thermally and electrically, excellent wear and corrosion resistance, are safe and reliable.
