Medicine 99% Al2O3 Alumina Ceramic Piston Plunger for Pumps

Medicine 99% Al2O3 Alumina Ceramic Piston Plunger for Pumps

Alumina ceramic piston / plunger 


one. Higher warmth resistance : Alumina ceramic has excellent thermal balance,which indicates that it is widely employed in regions exactly where resistance to large temperatures is vital.
two. Very good dress in resistance : Alumina ceramic is the substance of choice for alumina use parts.
three. High corrosion resistance : It is insoluble in h2o and only slightly soluble in sturdy acid and alkaline remedies. Great chemical security of alumina leads to substantial corrosion resistance.
