Alumina Ceramic Sheet
My factory looking for distributors.
Advantages of alumina ceramic sheet
1. Alumina Ceramic Sheet high temperature resistance: They can withstand temperatures up to 1600℃ in long use(Al2O3≥99%).
2. Alumina Ceramic Sheet high electrical insulation: Alumina ceramic substrates have a dielectric constant of 10 and can be used as an insulator for high voltage applications.
3. Alumina Ceramic Sheet low thermal expansion: They have a low coefficient of thermal expansion, making it suitable for applications that require a consistent temperature.
4. Alumina Ceramic Sheet chemical resistance: Highly resistant to corrosion, acids, alkalis, and solvents.
5. Alumina Ceramic Sheet high mechanical strength: Highly resistant to mechanical shock and vibration, making it suitable for use in dynamic environments.
6. Alumina Ceramic Sheet low cost: Relatively low cost compared to other materials with similar properties.
Applicatons of alumina ceramic sheet
1. Alumina ceramic sheet is often used in chemical and physical grinding environment, especially high purity alumina is a very good material for producing wear-resistant components.
2. Alumina ceramic sheet include shafts, pistons, bearings and mating end face seals.
3. Alumina ceramic sheet are mainly used in chemical and physical conditions and are good corrosive media. These components can be used to manufacture circulating pumps, reciprocating pumps and resonator-supported products.
4. We use ceramic injection molding and grinding to produce a variety of complex components with strict surface finish and flatness requirements. At the same time, our manufacturing process can also meet the requirements of small and batch production.
5. Alumina ceramic sheet is often used in water resources management, medical treatment, automobiles, telecommunications and household appliances applications.
