Alumina ceramic piston / plunger
Characters:
1. Large heat resistance : Alumina ceramic has exceptional thermal steadiness,which implies that it is broadly utilized in areas in which resistance to large temperatures is vital.
2. Very good wear resistance : Alumina ceramic is the content of choice for alumina use parts.
three. Substantial corrosion resistance : It is insoluble in drinking water and only slightly soluble in strong acid and alkaline answers. Very good chemical balance of alumina prospects to high corrosion resistance.
