The Sunflex Metal management team, have over 35 years of collective experience in the steel industry, and we are one of the largest Copper Nickel Press Fittings manufacturers in Mumbai, India. We produce these Copper Nickel Press Fit Pipe and Fittings as per DIN 86019 and with a factory standard governing the accuracy of dimensions and surface quality. For seawater systems Copper-nickel alloy Press Fittings (CuNi 90/10) are most suitable in piping connection. The Machinability of Copper nickel (based on free-cutting brass = 100) is 20. The Poisson’s Ratio of Copper nickel (C71500 annealed) is 0.325.
Copper Nickel Press Fit Pipe System have been time proven, to protect attacks from rough marine waters. For those wanting to save money and time during the installation or repairing of a pipe system, the solution lies in the usage of press fittings of copper nickel. As compared with soldering, welding and brazing, by using press fittings, it is possible to make pipe connections faster and with much lesser effort. Fact is, press fittings are an excellent way of connecting pipes, for a huge number of applications and that is why professionals and industries all across the globe, rely on press fittings made from copper nickel. 90/10 Cupronickel Press Fittings properties is that it contains 10% nickel alloy and 90% copper. To improve its resistance to corrosion from various media, manganese and iron are added to it in small quantities. The Molecular Formula of Copper nickel is CuNi. The Elongation at Break of Copper nickel (rolled-H04 for flat products/hard drawn-H80 for tubing), is 11.00% and its Elongation at Break (annealed), is 40%. The Yield Strength (annealed) of Copper nickel is 15000 psi (103 MPa). Copper Nickel pressfitting systems have very good antifouling properties and excellent fabrication qualities.
