Alumina ceramic piston / plunger
People:
1. High heat resistance : Alumina ceramic has superb thermal balance,which signifies that it is commonly employed in locations in which resistance to high temperatures is essential.
two. Very good use resistance : Alumina ceramic is the substance of selection for alumina put on areas.
3. Substantial corrosion resistance : It is insoluble in drinking water and only slightly soluble in strong acid and alkaline answers. Excellent chemical security of alumina leads to high corrosion resistance.
