Different diameter alumina ceramic rings

Alumina ceramic ring is a ceramic ring-shaped part made of high-purity alumina material, which has a variety of excellent properties and is widely used in many fields.

Performance parameter
High purity: The main ingredient is alumina, and the content is usually above 99%.
High hardness: Mohs hardness is 9, second only to diamond, capable of resisting wear and scratches.
High temperature resistance: able to maintain stability in high-temperature environments, with a maximum operating temperature of up to 1800 ° C.
Corrosion resistance: It has good corrosion resistance and can resist the attack of acids, alkalis and other chemicals.
Insulation properties: Excellent electrical insulation properties, capable of blocking the flow of current, suitable for use in the fields of electronics and electrical engineering.
Low density: The density is 3.9g/cm ³, much lower than that of metal materials, which can reduce the load on equipment.

Application field
Chemical industry: Due to its corrosion resistance and high temperature stability, it is often used as a lining material for reactors, pipelines, and vessels to protect equipment from corrosion and high temperatures.
Electronic engineering: Insulation properties make it an important component of electronic components, such as insulating sleeves, electronic ceramic capacitors, etc.
Machinery industry: Hardness and wear resistance make it widely used in the field of machinery, such as bearings, bushings, mechanical seals, etc.
Mining industry: can be used as abrasive and polishing materials to improve the processing efficiency and surface finish of ore.

Alumina ceramic rings play an important role in many high-tech fields due to their excellent physical and chemical properties.
