Alumina ceramic
Alumina ceramics is an excellent electrical insulator structural ceramic based on alumina (Al2O3) material, and it is also one of the most widely used advanced ceramic materials. In addition, it has the characteristics of insulation resistance, withstand voltage, high strength, good thermal conductivity, low dielectric loss, stable electrical performance, and extremely resistant to wear and corrosion. Used in electronic ceramic substrates, ceramic electrical insulation, vacuum devices, porcelain devices, spark plugs and other products. Alumina components are widely used in electronics, pump components and automotive sensors. We can manufacture parts through hot pressing, dry pressing, isostatic pressing and extrusion production technology.
The alumina component can be formed by a variety of manufacturing techniques, such as uniaxial pressing, hot pressing, dry pressing, isostatic pressing, injection molding and extrusion production. It can also be finished by precision grinding and fine grinding, laser processing and various other processes.
