Diamond Polished Wear Resistance Precision Alumina Zirconia Ceramic Piston
Diamond Polished Wear Resistance Precision Alumina Zirconia Ceramic Piston
Description:
The Ceramic piston is made of high-purity ceramic raw materials, which are formed by dry pressing or cold isostatic pressing, high-temperature sintering and precision machining.Ceramic piston can work in the acid and alkali corrosion conditions, high toughness and low friction coefficient, high pressure environment for a long time, and the maximum temperature to 1800 ºC (3272ºF)...Molding process is mainly hot, dry pressure, isostatic pressing; Products alumina purity to meet customer requirements.
