Diamond Polished Wear Resistance Precision Zirconia Ceramic ring
Description:
Zirconia ceramic has the advantages of super hardness, high wear-resisting,good corrosion resistance and electric insulation,resistant acid-base,high intensity,thermostable,high temperature tolerance,good insulation,high strength,precision process,high mechanical strength,good chemical stability.
Zirconia ceramic seal ring has proven itself to be useful and helpful for exhaust valves and flaps. Its excellent surface properties, high strength, low Young’s modulus and high abrasion resistance are paired with a thermal expansion coefficient comparable to steel, making it an ideal material for composite steel bearings working at high temperatures.
