Description
Good Insulating Electrical Ceramic Insulator Alumina Ceramic Parts
Alumina ceramic parts properties:
- Very high compressive strength (2,000 to 4,000 MPa)
- High hardness (15 to 19 GPa)
- Moderate thermal conductivity (20 to 30 W/mK)
- High corrosion and wear resistance
- Good gliding properties
- Low density (3.75 to 3.95 g/cm3)
- Operating temperature without mechanical load 1,000 to 1,500°C.
The advantages of alumina ceramic parts:
1.High temperature resistance
Extreme high temperature stability under reducing, inert and high vacuum condition under high temperature up to 1800C.
2.High hardness
Rockwell hardness of high alumina ceramics is up to HRA80-90
which is second only to diamond and far exceeds wear-resistant steel and stainless steel.
3.Excellent wear resistance
The wear resistance of high alumina ceramics is 266 times that of manganese steel and 171.5 times that of high chromium cast iron.
Applications of alumina ceramic parts:
Alumina ceramic parts finds extensive use in a wide range of industries and applications.
In the automotive industry, alumina ceramic is employed in the production of components such as ceramic spark plugs, ceramic oxygen sensors,
and ceramic diesel particulate filters, ceramic heater, ceramic guide, ceramic roller, ceramic shim part and so on.
