High Mechanical Strength Alumina Ceramic Pistons and Plungers

Alumina ceramic piston / plunger 


one. Substantial heat resistance : Alumina ceramic has outstanding thermal security,which indicates that it is widely utilized in regions the place resistance to large temperatures is important.
two. Very good wear resistance : Alumina ceramic is the content of selection for alumina wear parts.
three. High corrosion resistance : It is insoluble in h2o and only marginally soluble in robust acid and alkaline answers. Good chemical balance of alumina leads to substantial corrosion resistance.
