Wear Resistance Alumina Ceramic Tubes With Good Insulation Performance
About Alumina Tubes
Alumina Ceramic tubes have exceptional hardness and strength, resistance to chemical attack and wear, low dielectric loss and excellent electrical insulation properties. Additionally, Alumina can be metallized for brazing to other metals, highly polished, and comes in a variety of purities depending on it use. Due to these outstanding properties ceramic Alumina tubes are used in a wide range of industrial and advanced applications.
1. High hardness.
2. High heat resistance : Alumina ceramic has excellent thermal stability,which means that it is
widely used in areas where resistance to high temperatures is essential.
3. Good wear resistance : Alumina ceramic is the material of choice for alumina wear parts.
4. High electrical resistivity : Alumina is an electrically insulating material.
5. High corrosion resistance : It is insoluble in water and only slightly soluble in strong acid and
6 Good chemical stability of alumina leads to high corrosion resistance.
