High Temperature Resistance 95% Alo3 Alumina Ceramic Sealing Ring

Material introduction:

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.

 
Ceramic features
 
1) High hardness.
2) High heat resistance: alumina ceramic has excellentthermal stability,which means that it is widely used in areas where resistance to high temperatures is essential.
3) Good wear resistance: alumina ceramic is the material of choice for alumina wear parts.
4) High electrical resistivity: alumina is an electrically insulating material.
5) High corrosion resistance: it is insoluble in water and only slightly soluble in strong acid and alkaline solutions. Good chemical stability of alumina leads to high corrosion resistance.
 
Applications:
1) High power equipments.
2) IC MOS pipe
3) High frequency prower source, communication, mechanical equipment.
4) Heavy current, heavy voltage, high temperature, thermal conductive insulating parts.
