Diamond Polished Alumina Ceramic Parts Wear Resistance Precision Alumina Ceramic Tube
Diamond Polished Wear Resistance Precision Alumina Ceramic Tube
Description:
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. UNIPRETEC 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.

Advantages:
1. Superior wear resistance compared with other material.
2.Excellent wear resistance against acid and alkali.
3.Excellent resistance against big hard material without breakage.
4. Smooth surface makes excellent flow speed and avoid blacking the pipe system.
5.Reduce the frequency of maintenance to the facility, so as to reduce the cost and labor expense.
Application:
Wear resistant ceramic tube is conveying granular material, grinding, corrosive medium, such as the ideal wear and corrosion resistance, pipelines, widely used in electric power, mining, iron and steel, cement, chemical industry etc.
