99% Alumina Plunger Al2O3 Ceramic Piston for Pump

99% Alumina Plunger Al2O3 Ceramic Piston for Pump

Alumina ceramic piston / plunger 


1. Large heat resistance : Alumina ceramic has exceptional thermal stability,which signifies that it is extensively used in regions where resistance to substantial temperatures is important.
2. Very good dress in resistance : Alumina ceramic is the material of option for alumina dress in components.
3. Higher corrosion resistance : It is insoluble in h2o and only a bit soluble in powerful acid and alkaline answers. Excellent chemical steadiness of alumina leads to higher corrosion resistance.
