● 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
