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.

  • Electrical Conductivity: Copper is an excellent conductor of electricity therefore, it is an essential part in the production of electrical wires and electronic components for efficient transmission of electrical signals.

    Disadvantages:

  • High Cost: Copper, including UNS C70620, is rather dear compared to other materials. This may be a profound factor when copper is used extensively in the project.

  • Susceptibility to Corrosion in Certain Environments: Although in general it is corrosion resistant dietary copper corrodes at acidic and high chloride environments which it is exposed.

  • Low Strength at Elevated Temperatures: The melt strength of copper is weakened at high temperatures thus limiting its use in applications such as high strength at elevated temperatures.

  • Risk of Galvanic Corrosion: UNS C70620 copper subject to galvanic corrosion due to dissimulating metals with seawater electrolyte and therefore additional protective measures might be required.

  • Oxidation and Tarnishing: Copper itself oxidizes over time, and it therefore turns dark which might influence its look and therefore makes periodic maintenance necessary to bring it back to life.
