Main Advantages of Alumina Ceramic Disc Cartridge
Our ceramic disc cartridges are made of high-purity 95% Al₂O₃ alumina ceramic, primarily used in temperature control valves, diverter valves, surf and massage bathtub mixers, and LPG valves. These ceramic discs offer excellent sealing performance, high compressive and flexural strength, and outstanding durability—tested for over 500,000 cycles.
Key Properties of Alumina Ceramic Discs
Excellent Chemical Resistance
Resistant to acid, alkali, and chemical cleaning agents.High Pressure Resistance
Maintains performance under high-pressure conditions without deformation or leakage.Self-Cleaning Surface
Effectively resists lime scale build-up even at high water temperatures, prolonging service life.Corrosion and Abrasion Resistance
Non-corrosive material with exceptional wear resistance, ensuring long-term reliability.
