Alumina ceramic piston / plunger
People:
one. Higher heat resistance : Alumina ceramic has excellent thermal balance,which means that it is commonly used in locations where resistance to substantial temperatures is crucial.
2. Excellent wear resistance : Alumina ceramic is the substance of selection for alumina dress in areas.
3. High corrosion resistance : It is insoluble in h2o and only somewhat soluble in strong acid and alkaline solutions. Good chemical stability of alumina sales opportunities to large corrosion resistance.
