● Description:

    Alumina ceramics have good conductivity, mechanical strength and high temperature resistance. Alumina ceramic is a kind of widely used ceramic. Because of its superior performance, it has been used more and more widely in modern society, meeting the needs of daily use and special performance.



  Feature:

1. Corrosion resistance, excellent rust resistance and intergranular corrosion resistance;

2. Wear resistance, good mechanical strength and ductility, high hardness, wear resistance and durability;

3. High temperature resistance, the use temperature limit can reach about 600 ℃;

4. Acid and alkali resistance, good corrosion resistance to alkali solution and most organic and inorganic acids;

5. High cost performance, cheaper than zirconia ceramics
