Alumina ceramic piston / plunger
People:
one. High heat resistance : Alumina ceramic has superb thermal security,which implies that it is broadly utilised in areas exactly where resistance to high temperatures is crucial.
2. Very good use resistance : Alumina ceramic is the material of option for alumina use parts.
3. High corrosion resistance : It is insoluble in drinking water and only a bit soluble in robust acid and alkaline remedies. Great chemical steadiness of alumina qualified prospects to substantial corrosion resistance.
