What is a C71500 copper nickel tube?
ASTM B111 C70600 (C706) & C71500 (C715), Copper nickel offers excellent corrosion resistance, especially in marine salt water environments. The main, wrought copper-nickel alloys chosen for sea water service contain 10 or 30 percent nickel. They also have important additions of iron and manganese which are necessary to maintain good corrosion resistance. Some of the primary uses for C706 include copper nickel fittings (CuNi Fittings) as well as condensers and exchanger shells.

FAQ
Q: How do you weld C71500 copper-nickel pipe?
A: It is readily weldable using Gas Tungsten Arc Welding (GTAW/TIG) and Gas Metal Arc Welding (GMAW/MIG) processes. Use matching filler metals like ERCuNi or 70/30 CuNi rods and ensure proper shielding gas to prevent oxidation.
Q: Can C71500 be bent and formed easily?
A: Yes, it has good ductility and can be cold-formed using standard techniques. Annealed temper pipe is preferred for severe forming operations.
Q: What are the most common applications for C71500 pipe?
A: Its primary use is in marine and offshore systems, including seawater piping, condensers, heat exchangers, hydraulic lines, and firefighting systems.
Q: Why is C71500 used in heat exchangers and condensers?
A: Its combination of excellent corrosion resistance, good fabricability, and low thermal conductivity (which helps maintain fluid temperature) makes it ideal for these critical components.
