Alumina ceramic valve core sleeve Alumina ceramic is a ceramic material with α-Al2O3 as the main crystal phase. The alumina ceramics used in engineering generally have an Al2O3 content between 75% and 99.9%. The flexural strength of Al2O3 porcelain sintered products can reach 250MPa, and the hot-pressed products can reach 500MPa. The purer the Al2O3 composition, the higher the strength. The strength can be maintained up to 900°C at high temperatures. Using the mechanical strength of Al2O3 porcelain, it can be made into device porcelain and other mechanical components. The Mohs hardness of Al2O3 ceramics can reach 9, plus it has excellent wear resistance, so it is widely used in the manufacture of tools, grinding wheels, ceramic nails, bearings, etc. Among them, Al2O3 ceramic tools and industrial valves are the most widely used.
