UNS C71520 Copper Nickel Chemical Composition Properties, Grade, Chart and Document

UNS C71520 combines an alloy of 70.00% copper and 30.00% nickel, in addition to minute amounts of iron and manganese, makes a copper alternative. This alloy demonstrates exceptional ability to marine corrosion safety enabling its application to shielding of multipurpose shipbuilding, deep-sea oil mining and seawater piping safety systems. In high performance also vapor compression, it is important to mention that it does not have a corrosion reaction and has a thermal stability; and therefore is preferable for heat exchangers and condensers. Along with it, they both are of the same grade B466 and B111 as well. The alloy is chemical composition which includes copper, nickel, iron, and manganese, as well as other elements in trace amounts. This alloy has as a key advantage such properties as high ductility, high resistance to corrosion and biofouling, while also being a perfect match for heat transfer. Relevant documents for this piece equipment include a material test report, and a certificate indicating that this piece of equipment is meeting industry standards.

UNS C71520 Copper Chemical Composition And Grade Table

UNS C71520 is usually identified as 70/30, which refers to the composition of copper and nickel that are used to produce an alloy with the ability to resist corrosion significantly in water solutions with added salt. The chemical composition of it is typically Copper 70%, nickel 30%, and the member of other metal elements, such as iron and manganese, is also included. These materials provide excellent mechanical properties trade and are also used in the marine operations such as shipbuilding, offshore projects designing and desalination. The corrosion resistance and ownability of biofouling are another advantage that increase his confidence to use it under water as components. C71520 earned the reputation for ruggedness, which is the reason that the strength is so important to several industries.
