> CSZ's Superior Resistance to Low Temperatures

Consider CSZ a top candidate when choosing a material for high strength and toughness in moist, challenging environments. With high flexural strength and very high compressive strength this material is ideally suited as a structural component in sensors, instrumentation, probes, pumps and fluid control systems.

CSZ offers a more robust Stabilized Zirconia material when low temperature degradation properties are in question, displaying a reduced vulnerability of molecular water attack compared to YTZP or MSZ, The ability of this material to withstand high temperature, wet operating conditions elevates its performance above other ceramic materials.
