AlN Ring

Ceramic seal rings give full play to the high insulation, high strength, high-temperature resistance, aging resistance, corrosion resistance, and other characteristics of ceramic materials. It has good air tightness after metallization welding, has extremely high-temperature resistance, and can withstand rapid temperature changes. The mechanical strength is high and the dimensional tolerance of the seal is small, which greatly improves the service life and safety.
