Copper Nickel Pipe

Farmer’s Copper Ltd. maintains a broad inventory of Copper Nickel, also known as cupro nickel, C70600 (90/10) and C71500 (70/30) in pipe form. Our inventory of ASTM B466/ASME SB466 is composed of C706 in SCH 40 & 80, along with Class 200, in addition to C715 in SCH 80. The C706 Copper Nickel pipes are either annealed, light drawn or hard drawn whereas the C715 pipes are annealed or hard drawn.

Copper Nickel pipes are commonly used in seawater piping due to its complete resistance to barnacles and other marine organisms. Its resistance makes seawater fire fighting systems, desalination water systems, and similar applications much more reliable.
