Sunflex Metal is one of the largest Copper Nickel Elbows manufacturer & traders with branches in most major centres in India. Copper Nickel Elbow is a pipe fitting that is used immensely in domestic and industrial plumbing applications. The Machinability of Cuni Elbow is 20. The Thermal Expansion Co-efficient of Cuni Pipe Elbow (@20-300°C/68-572°F) is 9.00 µin/in °F (16.2 µm/m °C). The Poisson’s Ratio of Cuni 90/10 Elbow is 0.325. Copper nickel alloy elbow corrosion resistance is due to the fact that it contains additions of manganese and iron, which are vital to ensure excellent resistance to corrosion.

The Yield Strength of Copper Nickel 90 Degree Elbow is 15000 psi (103 MPa). The Chemical Composition of these elbows are Cu 71.25-76.5, Fe ≤ 0.20, Pb ≤0.050, Mn ≤ 1.0, Ni 23.5-26.5 and Zn ≤ 1.0. Cupro Nickel Buttweld Elbow is used in various industries like petrochemical plants, fertilizer plants, LNG plants, thermal power stations, chemical refineries, offshore platforms, etc. 90/10 Copper Nickel Navy Butt Weld 90º Elbow 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). Cupro Nickel Elbows chemical composition is that of 90% copper and 10% nickel. And most of these commercial alloys contain iron, manganese and tin, so as to enhance specific properties of these alloys. Cast alloys also have silicon and niobium present in them. Elbows made from copper nickel are in big demand because of their resistance to pitting, their resistance to corrosion and their anti-fouling properties. As such, elbows made from copper nickel are used in various applications in industrial condensers, power installations, offshore drilling piping systems, evaporating equipment, heat exchangers and fabrication.
