Description

Industrial Insulation 95%~99%Alumina Al2o3 Ceramic Washer

The advantages of alumina al2o3 ceramic washer:

1.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.

2.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 al2o3 ceramic washer:

1.Alumina al2o3 ceramic washer find 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.

2.In the aerospace industry, alumina ceramic is utilized in the manufacturing of parts and components for aircraft engines, avionics, and satellite communications systems. Its ability to withstand high temperatures and harsh environmental conditions makes it a valuable material for these critical applications.

Finishing ability

The maximum height is 600mm
The maximum length is 2500 mm
The maximum CNC length is 1200 mm

Surface roughness:

The surface processing of ceramic plates and washers can achieve very high precision: the inner hole surface can reach 0.005mm,

the outer hole surface can reach 0.001mm, and the mirror polishing can reach Ra0.1.
