Ball valves are commonly made from materials like nickel-plated brass or nickel-plated aluminum, depending on the application. Brass is widely preferred for its durability, corrosion resistance, and suitability for high-pressure/temperature environments. Aluminum, while lighter, is less robust and typically used in low-pressure or lightweight applications (e.g., portable systems). The nickel plating enhances corrosion resistance and provides a smoother surface for sealing. Always verify the vendor’s specs, discrepancies may arise due to varying use cases or vendor-specific designs. For most industrial or plumbing uses, nickel-plated brass is standard, but confirm based on your system’s pressure, fluid type, and environmental conditions.
