The main characteristics of alumina ceramic tubes
1. Outstanding wear resistance, over 276 times in comparison with traditional stainless steelThe Description of Alumina Tubes
Alumina(Aluminum Oxide, Al2O3) is the most extensively used advanced ceramic material due to its outstanding property characteristics and cost-effective advantage. As the purity increases, both wear resistance and corrosion resistance also increase, so alumina is 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.Remark:
We are dealing with a variety of alumina ceramic tubes in different purities, different geometries, different colors, and different precision levels.General | Properties | Unit | 99.5% Al2o3 | 99% Al2O3 | 96% Al2O3 |
