Description
Corrosion Resistance Alumina Ceramic Tube Sleeve
Alumina ceramic, also known as aluminum oxide (Al2O3), is a versatile and high-performance ceramic material that has gained significant attention in various industries due to its exceptional mechanical, thermal, and electrical properties.
The advantages of alumina ceramic tube sleeve:
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.
3.High temperature resistance
Extreme high temperature stability under reducing, inert and high vacuum condition under high temperature up to 1800C.
Applications of alumina ceramic tube sleeve:
1.Alumina ceramic tube sleeve 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.
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.
