Pink Red Color Textile 95% 99% Al2O3 Alumina Ceramic Eyelets
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.
We can supply and custom made the steatite ceramic products according to customer's drawings, samples and performance requirement.
Applications:
Heating element holders
Stand off insulators
Interlocking insulating beads
Splitbush insulators
Lamp bases and caps
Regulator parts
