DutyCeramic
Zirconia offers high strength, wear resistance, and flexibility. It has a superior surface hardness, the highest level of impact toughness for a bearing grade ceramic, corrosion resistance, elastic modulus and thermal expansion similar to bearing steel, and good high-temperature performance. It has low thermal conductivity, is electrically non-conductive and non-magnetizing, making it a suitable material to replace metals in many applications where isolation is essential.One notable weakness is high-temperature steam will degrade Zirconia.
