What is a C71500 copper nickel tube?
C71500 copper-nickel tubes are widely used in various industries, including marine environments, power generation, offshore operations, oil and gas, and defense. Drawn copper-nickel tubes combine excellent hot and cold working properties, extremely high resistance to seawater corrosion and erosion, and high strength. Typical applications include distillation and desalination plants, marine coolers, and heat exchangers.
GNEE manufactures straight-drawn copper-nickel tubes as well as copper-nickel tube assemblies made from 70/30 and 90/10 copper-nickel alloys. All our drawn copper-nickel tubes are manufactured, cleaned, and supplied according to the most popular European and American specifications, such as C70600, C71500, CN102, CN107, Kunifer 10, Kunifer 30, NES 779, NES 780, DIN 86019, CuNi10Fe1Mn, CuNi30Mn1Fe, DEF-STAN 02-779, DEF-STAN 02-780, CW352, and CW354H.
