Anti-oxidation Industrial Ceramic Parts Oil Drilling Machines
Industrial Ceramic Intriduction
Aluminium Oxide, Al2O3 is the most widely applied and cost effective technical ceramic material. It offers a combination of superior mechanical strength and electrical properties, wear resistance and corrosion resistance. The maximum working temperature is up to 1700 °C with relatively high thermal conductivity. It is also an electrically insulating material with a high electrical resistivity. The good corrosion resistance makes it insoluble in water and slightly soluble in strong acid and alkaline solution.
1.Material: Different grade alumina, zirconia, silicon carbide, steatite, cordirite and aluminum nitride available;
2.Available type: ceramic housing, ceramic frame, ceramic shaft, ceramic wafer and so on.
3.Design capability: varity of standard ceramic parts or customized design capability
4.Prototype to mass production capability
5.Features: High insulation, anti-chemistry, exceptional wear resistance, resistant high temperature, excellent physical properties.
Key parameters control capability:
