alumina ceramic machinery pin piston plunger Reputation depends on quality,  quality comes from Hard! Alumina Ceramic: Characteristics of the use of alumina ceramics: First, light weight The density of alumina ceramics is 3.5g/cm3, which is much less than half of steel. Second, the hardness is large According to the Shanghai Institute of Ceramics of the Chinese Academy of Sciences, the Rockwell hardness of alumina ceramics is HRA80-90, and the hardness is only second to diamond, far exceeding the wear resistance of wear-resistant steel and stainless steel. Third, good wear resistance According to the Institute of Powder Metallurgy, Central South University, the wear resistance of alumina ceramics is equivalent to 266 times that of manganese steel and 171.5 times that of high chromium cast iron. According to our customer tracking survey for more than ten years, under the same working conditions, we can extend the service life by at least ten tim…
