Alumina ceramic piston / plunger
People:
one. Higher warmth resistance : Alumina ceramic has exceptional thermal stability,which signifies that it is extensively utilized in places the place resistance to higher temperatures is essential.
2. Very good wear resistance : Alumina ceramic is the substance of option for alumina wear parts.
3. High corrosion resistance : It is insoluble in drinking water and only marginally soluble in strong acid and alkaline solutions. Good chemical security of alumina qualified prospects to large corrosion resistance.
