Wear Resistance 95% 96% 99% Al2O3 Ceramic Shaft Alumina Ceramic Piston Plunger

Alumina ceramic piston / plunger 


1. Higher warmth resistance : Alumina ceramic has outstanding thermal steadiness,which implies that it is commonly utilised in regions in which resistance to large temperatures is vital.
two. Very good dress in resistance : Alumina ceramic is the substance of decision for alumina put on components.
three. Higher corrosion resistance : It is insoluble in water and only marginally soluble in powerful acid and alkaline options. Very good chemical security of alumina leads to substantial corrosion resistance.
