1.Outstanding wear resistance, over 276 times in comparison with traditional stainless steel
2.Great mechanical properties, with diamond-like hardness, excellent compressive and dense bodyThe Description of alumina ceramic tubes
Alumina(Aluminum Oxide, Al2O3) is the most extensively used advanced ceramic material due to their outstanding property characteristics and cost-effective advantage. As with the purity increases, both wear resistance and corrosion resistance also increases, so alumina are grouped together based on purity levels, including 75% alumina, 85% alumina, 90% alumina, 95% alumina, 99% alumina, 99.5% alumina, 99.8% alumina, 99.9% alumina.Other types of alumina ceramic tubes
