Alumina ceramics have excellent dielectric strength, high-frequency loss is relatively small but high-frequency dielectric strength is good, followed by alumina ceramic raw materials with temperature resistance, small linear expansion coefficient, high impact toughness and heat conduction Good rate and other characteristics, alumina ceramics have the characteristics of chemical corrosion resistance and molten metal resistance, but it is not known that alumina ceramics are flame retardant, stainless steel is strong and not easy to be destroyed, which have good characteristics that other materials and metal composite materials cannot be compared.

Alumina processed ceramic rings have excellent mechanical strength, high temperature resistance, wear resistance, corrosion resistance, good insulation performance and durability. Characteristics of alumina processed ceramic rings1.Corrosion resistance: The material itself has corrosion resistance characteristics, and can be used in strong acids, strong alkalis, inorganic, organic salts, seawater and other fields outside of China. 2.High temperature resistance: Alumina ceramic rollers can maintain their strength up to90°Ctemperature. It can be seen that alumina ceramic rollers can be widely used in high-temperature equipment such as furnace cellars, plastics, and steel;3.High hardness, Mohs The hardness is9. 4.Electrical insulation.Due to electrical resistance. Alumina processed ceramic ring parts have high hardness, high strength, low expansion coefficient, insulation, wear resistance and corrosion resistance. Meter, instrument, chemical industry, communication, communication and other industries.

Alumina ceramic tube has good electrical conductivity, mechanical strength and high temperature resistance. It should be noted that ultrasonic cleaning is required. Alumina ceramics are ceramics with a wide range of uses. Due to its superior performance, it has been more and more widely used in modern societytomeet the needs of daily use and special performance.
