If you ask what is Copper Nickel 90/10 Round Bar, then they are round shaped bars made of austenitic alloy that comprises 90% copper, 10% nickel, along with other components like manganese and iron. The ASTM B151 C70600 material is known for showing high resistance to the acidic environments, especially sulphuric acid, which is the most lethal. The Copper Nickel 90/10 Rod is also known for its excellent resistance to corrosion, which includes both pitting and crevice corrosion. The ASTM B151 UNS C70600 material is able to retain its properties even in the presence of chemicals containing chlorides.
The chemical composition of the CuNi 90/10 Hex Bar is such that it shows great flexibility even in hot working conditions, provided they are applied correctly. It is due to the strength of the Copper Nickel 90/10 Rod that they do not get damaged quite easily, even if it gets exposed to a temperature above 1200 degrees F and that too for a long period of time. The ASTM B151 UNS C70600 Flat Bar is highly demanded due to its properties and long-lasting service life. In other words, it can be said that the UNS C70600 Forged Bar has a perfect blend of enhanced mechanical properties, with corrosion resistance, and high fabricability. However, it is to be noted that the ASTM B151 GR. C71500 products are subjected to crevice corrosion and pitting when they get exposed to warm chloride environments.
It is also easy to customize the ASTM B151 C70600 Square Bar in desired size and dimensions. Their shapes can also be customized and they can be given desirable surface appearance. For example, the CuNi 90/10 Bright Bar comes with a shiny surface appearance and thus, they can be used in places that are highly visible.
All the above properties and features make the CuNi 90/10 Cold Drawn Bar highly applicable in industries such as petrochemical, energy, chemical, power plant, food processing, oil and gas, etc.
90/10 Copper Nickel Bar offers superb corrosion resistance, even in an environment such as marine salt water. Cupro Nickel 90/10 Round Bar has a Density of 0.323 lb/in³ (8.94 g/cm3). The Elongation at Break of 90/10 Cu-Ni Rods (rolled-H04 for flat products/hard drawn-H80 for tubing), is 11.00% and its Elongation at Break (annealed), is 40%. The Poisson’s Ratio of UNS C70600 Hex Bar (C71500 annealed) is 0.325. Copper Nickel 90/10 Round Bar contains nickel and copper and strengthening elements like manganese and iron. These bars of copper nickel are used a lot in ammunition, condenser tubes, cooling circuits, sea water corrosion-resistant assemblies, etc.
Cu-Ni 90/10 Bright Bar properties are that of 90% copper and 10% nickel alloy and to increase the corrosion resistance, manganese and iron are added to it. It has a Tensile Strength (annealed) of 52000 psi (359 MPa) and it has a Tensile Strength (rolled-H04 for flat products/ hard drawn-H80 for tubing) of 78000 psi (538 MPa). The Chemical Composition is Cu Bus Bar is 71.25-76.5, Fe ≤ 0.20, Pb ≤0.050, Mn ≤ 1.0, Ni 23.5-26.5 and Zn ≤ 1.0. ASTM B151 Cupro Nickel 90/10 Forged Bars has properties that display high resistance to bio-fouling and seawater corrosion. Because of their resistance to biofouling, round bars of copper nickel find use in various application areas involving seawater intake screens, oil rigs and platforms, chemical and marine environments of boat and ship hulls, seawater and hydraulic platforms, heat exchange equipment, fish farming cages and desalination plants. As there is no need for surface protection by 90/10 and due to the fact that it delivers extra safety, Cu-Ni DIN 2.0872 Square Bar is now being used in cooling systems and in hydraulic and brake suspension systems in commercial vehicles and cars.
