Alumina ceramic piston / plunger
People:
one. High heat resistance : Alumina ceramic has outstanding thermal stability,which indicates that it is widely employed in locations exactly where resistance to large temperatures is vital.
two. Very good put on resistance : Alumina ceramic is the material of option for alumina use elements.
3. High corrosion resistance : It is insoluble in drinking water and only a bit soluble in strong acid and alkaline options. Excellent chemical security of alumina prospects to large corrosion resistance.
