Alumina ceramic piston / plunger
Cijfers:
one. Large heat resistance : Alumina ceramic has outstanding thermal stability,which indicates that it is extensively used in areas in which resistance to large temperatures is vital.
two. Good use resistance : Alumina ceramic is the content of decision for alumina use elements.
3. Large corrosion resistance : It is insoluble in water and only marginally soluble in robust acid and alkaline solutions. Great chemical stability of alumina prospects to substantial corrosion resistance.
