Cupro Nickel Socket Weld and Threaded Fittings

Cupro-Nickel Socket Weld and Threaded Fittings are essential for applications requiring excellent corrosion resistance and strength, particularly in marine environments and for handling seawater. Cupro-nickel alloys, such as CuNi 90/10 (C70600) and CuNi 70/30 (C71500), are used extensively in these applications. Below is a detailed overview of the specifications, types, grades, and standards for cupro-nickel fittings.Cupro-Nickel Socket Weld and Threaded Fittings1.
