ASTM B151 C70600 Copper Nickel Weld Neck Flanges 1-1/4" SCH40 #150 ASME B16.5
ASTM B151 UNS C70600 Copper Nickel Alloy Flange is a type of flange made from a composition of 90% copper and 10% nickel. This blend of copper and nickel provides excellent corrosion resistance, making it suitable for various applications. The presence of nickel, iron, and manganese enhances its ability to withstand corrosive elements. Cu-Ni 90/10 weld neck flanges are commonly used in seawater piping systems, crankshafts, tubes for light-duty condensers, sea water pipe-work desalination units, and offshore platforms. These flanges are specifically designed to offer durability and resistance to harsh environments.
