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.The two common Seamless Copper-nickel alloys are Alloy 706 (C76000 – 10% nickel) and Alloy 710 (C71000 – 20% nickel).Eckhardt Steel & Alloys stocks Alloy 706 only; Alloy 710as well as other CuNi alloysare available as a special order.
