Advantages:
1.. High hardness, it is can be up to 1700 HV, and Super compressive strength up to 2240 Mpa
2. High heat resistance: Alumina ceramic parts offer excellent thermal stability, which means that it is widely used in areas where resistance to high temperatures is essential.
3. Good wear resistance: it is an ideal choice to wear parts in high abrasive industry
4. High electrical resistivity: used in all-electric products, electric heating products, and wear-resistant machinery parts.
5. High corrosion resistance: It is insoluble in water and only slightly soluble in strong acid and alkaline solutions. Good chemical stability of alumina leads to high corrosion resistance.
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.
