If you are wondering what is Copper Nickel 90/10 Pipe, then it can be defined as a pipe that has 90% copper and 10% nickel in its alloy. Other than that, the chemical composition of the CuNi 90/10 Pipe also consists of iron and manganese, which enhances the overall strength and corrosion resisting capabilities of the pipe. The 90/10 Copper Nickel Pipe comes with high ductility and toughness, which is why they are a popular grade for different marine and industrial applications. Due to the high toughness, the ASTM B466 UNS C70600 material is also used in several architectural applications.
The UNS C70600 Pipe possesses some good mechanical properties, which includes good resistance to stress corrosion cracking. They can also effectively resist erosion and biofouling in the seawater environment. The Copper Nickel Pipe 90/10 comes with excellent fabricability and they have good welding properties too. They have high resistance to hydrogen embrittlement. One of the best things about the MIL-T-16420K alloy 706 Round Pipe is that they can retain their properties down to the cryogenic temperatures. The CuNi 90/10 Seamless Pipe is more reliable and less prone to leakage compared to the welded pipes due to the absence of seams. This is why they are used for more critical applications, but they are more expensive than the CuNi 90/10 Welded Pipe too.
Due to all the above properties, pipes and other products made with the ASME SB 466 UNS C70600 material are used for a wide range of applications. This would include equipment in the following industries:
The 90/10 Pipe has great antimicrobial properties and that is why they are in high demand in the application areas related to hygiene and sanitary environments, like hospitals, kitchens, and various healthcare environments.
Cu-Ni 90/10 Pipe properties are that they exhibit tremendous resistance to corrosion by sea water, because of the significant quantity of iron and manganese that are present in them. The Elongation at Break of 90/10 Cu-Ni Seamless Pipes (rolled-H04 for flat products/hard drawn-H80 for tubing), is 11.00% and its Elongation at Break (annealed), is 40%. The Molecular Formula of ASME SB466 Cupro Nickel Pipe is CuNi. Copper nickel 90/10 fuel pipe has a Density of 0.323 lb/in³ (8.94 g/cm3). 90/10 Copper Nickel Pipe has superb antimicrobial properties. As an oldest 90/10 Copper Nickel Pipe suppliers in Mumbai SMI copper offers excellent scaling resistance CuNi 90/10 Pipe which has very good hot and cold workability. 90/10 copper nickel alloy pipe has a small temperature coefficient of electrical resistance.
UNS C70600 Welded Pipe has big demand in various applications such as heat exchanger bases and plates, electrical resistors, oil coolers, condenser tubes, air conditioning plants, heating cables, seawater desalination plants, anodes for TV tubes and light-current switches. Cu-Ni 90/10 Seamless Pipes chemical composition is that of Cu 71.25-76.5, Fe ≤ 0.20, Pb ≤0.050, Mn ≤ 1.0, Ni 23.5-26.5 and Zn ≤ 1.0. The Yield Strength (annealed) of Copper nickel is B466 C70600 Pipe 15000 psi (103 MPa). UNS C70600 Pipe has a Rockwell B Hardness of 69. Cupro Nickel DIN 2.0872 Welded Piping is solderable and it has low electrical resistivity. ASTM B466 Cupro Nickel 90/10 Seamless Pipes has excellent welding and fabrication properties. Copper Nickel 90/10 brake pipe is used in low heating temperature heating cables, plug connectors, electrical resistors, power stations, measurement resistors, finned tubes, dynamo slip rings, control and load resistors and in the chemical industry.
