UNS C70620 Copper Nickel Chemical Composition, Grade, Tables and Document

UNS C70620 is a Cu-Ni alloy that has excellent corrosion resistance and has been applied to the marine, and industry uses are the best areas. This element's composition is quite close to being so pure that it is comprised of about 90% copper and 10% nickel, with small amounts of iron and manganese. This improves the superior seawater corrosion, biofouling, and erosion resistance of the metallic material. The material is usually termed as 90/10 copper-nickel and it is standardized in accordance with ASTM B151 and ASME SB151. Its mechanical properties comprise a high tensile strength, a good ductility, along with excellent thermal conductivity. Tables that contain it elemental composition and mechanical properties can be found in the technical specifications of the industry records. In view of its successful employ in severe conditions, UNS C70620 applications are widely known in shipbuilding, offshore structures, heat exchangers and desalination plants.

UNS C70620 Copper Chemical Composition And Grade Table

UNS C70620 stands apart as a crucial copper-nickel alloy due to its remarkable capability to resist corrosion in saltwater environments. The alloy is basically made of copper (Cu) with nickel (Ni) and other micro-components, its chemical composition usually consists of 89% copper, 10% nickel, and 1% iron. It is in marine applications like building ships and ships, offshore structures, and desalination plants wherein this alloy's biocorrosion and corrosion resistances are critical due to its abilities to prevent biofouling and erosion. UNS C70620, with the combination of high strength and durability, is an ideal choice even in the most adverse marine conditions thus it drives manufacturing of different engineering projects.
