Yellow Advanced High Precision 95%-99.5% Alumina Ceramic Seal Ring

 

Feature:

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

alkaline solutions.

6) Good chemical stability of alumina leads to high corrosion resistance.
