Product Name: 95% Alumina (Al_2O_3) Ceramic Valve Disc for Faucets
Product Material: High-Purity 95% Alumina ($Al_2O_3$), engineered for high-cycle friction durability.
Material Characteristics: Extreme surface hardness (Vickers 1500+ HV), Outstanding wear resistance ($500,000+$ cycles), Corrosion resistance to hard water and chlorine, High compressive strength, Low friction coefficient, Excellent thermal stability (resists hot/cold water cycles).
Surface Finishing: Mirror lapping and polishing, Flatness $< 0.6 \mu m$ (2-3 light bands), Surface roughness $Ra < 0.2 \mu m$, Parallelism $< 0.01 mm$.
Application Fields: Single-handle kitchen mixer valves, Bathroom basin faucet cartridges, Thermostatic shower valves, Dual-control ceramic headworks, Industrial fluid control valves, RO water purifier dispensers.
Application Industries: Sanitary Ware (Residential and commercial plumbing), Advanced Machinery (Fluid control systems), New Energy (Water-cooled thermal management), Electronic Engineering (Chemical dispensing valves), Fluid Control (Valve manufacturing).
Processing Difficulties: Achieving nanometer-level flatness to ensure a vacuum-tight seal between the moving and stationary discs, Maintaining precise port geometry to ensure linear water flow control, Controlling material density to prevent micro-pitting over long-term use.
Processing Flow: Raw material spray drying, High-pressure dry pressing, High-temperature tunnel kiln sintering ($1650^{\circ}C$), Precision double-sided diamond grinding, Nano-grade mirror lapping, Ultrasonic deionized water cleaning, Light-band flatness testing, High-pressure leak verification, Secure industrial packaging.
Delivery Period: Standard valve sizes: 10-15 days, Customized port designs or special geometries: 20-30 days.
Our Alumina Ceramic Valve Discs are the gold standard for maintenance-free faucet operation. Engineered with a proprietary 95% alumina formula, these discs are polished to such extreme flatness that they bond together via surface tension, creating a perfect seal without the need for rubber gaskets in the friction zone. The diamond-like hardness prevents scratching from sand, limescale, or debris, ensuring a smooth, effortless handle movement for over 500,000 cycles. Designed for both domestic and heavy-duty commercial environments, our ceramic discs offer total immunity to corrosion and mineral buildup.
Key Features:
Zero Leakage Performance: Ultra-flat surfaces ensure a perfect seal under both high and low water pressures.
Extreme Longevity: Tested to exceed international standards ($EN817$, $ASME$) for lifetime durability.
Silky Smooth Operation: Low friction coefficient provides a consistent "new faucet" feel for years.
Mineral Resistance: Impervious to limescale and hard water deposits that damage metal valves.
Eco-Friendly: Precision flow control reduces water waste; lead-free and non-toxic material.
