UNS C70600 Flanges


Copper-nickel products have trace contents of elements like iron and manganese with the rest being split into 90% copper and about 10% nickel. Many industries acknowledge the fact that 90/10 Copper Nickel Pipe Flanges has superior resistance to both corrosions as well as erosion. One industry that primarily consumes this alloy is marine engineering. The resistance to seawater is a property that the Copper Nickel 90-10 WNRF Flanges has inherited from copper. This is a property that extends even in polluted marine environments, where the waters flow at high velocity. The alloy has good tensile strength and its use as Cu-Ni UNS C71500 Blind Flanges is much appreciated as the metal is able to withstand high pressure. Along with these properties, the alloy is highly ductile and can be easily formed into various shapes, making them relatively easy to form into shapes like the Werkstoff No.2.0872 Copper Nickel 70/30 Weld Neck Flange. Typically, welding is not the preferred permanent joining technique of these flanges. Copper and copper-nickel based alloys including the 90/10 Copper Nickel SORF Flange are soldered via an intensive process that involves cleaning, preparing and finally joining and finishing. Since this process is labour intensive, the result achieved via soldering is superior. The benefit of using Cu-Ni 90/10 Plate Flange in cryogenic temperatures is that unlike some conventional stainless steels or carbon steels, these flanges are not susceptible to cracking.
