Alumina ceramic piston / plunger
Figures:
one. Higher warmth resistance : Alumina ceramic has exceptional thermal steadiness,which implies that it is broadly used in locations exactly where resistance to substantial temperatures is essential.
two. Excellent dress in resistance : Alumina ceramic is the content of selection for alumina use parts.
three. High corrosion resistance : It is insoluble in water and only marginally soluble in sturdy acid and alkaline answers. Great chemical balance of alumina sales opportunities to substantial corrosion resistance.
