Thermal Conductivity Mechanical Plate High Temperature Resistance
Alumina Ceramic Plate
Alumina Ceramic (Aluminum Oxide or Al2O3) is an excellent electrical insulator and
one of the most widely used advanced ceramic materials.
Additionally, it is extremely resistant to wear and corrosion.
Alumina components are used in a wide range of applications such as
electronics, pump components and automotive sensors. us offers a variety of alumina compositions, including 92% Alumina,
95% Alumina, 96% Alumina, 99% Alumina, 99.5% Alumina and 99.8%
Alumina, but the 95% Alumina and 99% are the most widely used
materials. Alumina components can be formed by a variety of
manufacturing techniques such as uniaxial pressing, isostatic
pressing, injection molding and extrusion. Finishing can be
accomplished by precision grinding and lapping, laser machining and
a variety of other processes.
Feature:
- A variety of specifications available
- Satisfy various technical request
- Lower medium spoilage
- Good insulation performance and high temperature resistance
- Stiffness texture
- Used in all electric products, electric heating products and wear
resistant machinery parts
