Alumina (Al₂O₃) Ceramic Plunger:

Alumina (Al₂O₃) ceramic plungers are high-reliability precision components engineered for corrosive working conditions in the chemical industry. 
Crafted from high-density sintered aluminum oxide, these plungers deliver outstanding chemical inertness, refusing to react with most organic 
and inorganic chemical media. Compared with polymer and metal alternatives that are prone to corrosion and aging, 
they maintain stable performance in high-temperature and high-pressure corrosive environments, widely applied in chemical pesticide production, 
petrochemical refining and chemical reagent conveying systems.

High Purity 99 95 Alumina Ceramic Plunger Excellent Wear and Corrosion Resistance 0
