GNEE maintains a comprehensive inventory of ASTM B111 C71500 copper-nickel seamless tubes and supplies ASTM B111 C71500 products in a wide range of specifications. Due to their exceptional resistance to seawater corrosion, low susceptibility to marine biofouling, and excellent formability, these products are widely utilized in the field of marine engineering.
We supply copper-nickel seamless tubes that comply with the following standards: ASTM B466 70/30 (C71500), ASTM B466 90/10 (C70600), ASTM B111 70/30 (C71500), and ASTM B111 (C70600).
Copper-nickel alloys possess outstanding resistance to marine biofouling and marine corrosion, while also exhibiting excellent formability. The addition of nickel to copper results in a significant enhancement of both its strength and corrosion resistance.
The UNS C71500 copper-nickel alloy (Cupronickel) features moderate-to-high strength and demonstrates excellent creep resistance in high-temperature environments. Compared to copper-aluminum alloys or other alloys with similar mechanical properties, this alloy carries a relatively higher cost.
The C71500 copper-nickel alloy is a type of copper alloy, specifically classified as a copper-nickel alloy (Cupronickel). CW354H is the numerical designation for this material under EN standards, while C71500 serves as its UNS number. Furthermore, its chemical composition designation under EN standards is CuNi30Mn1Fe. Its British Standard (BS) designation is CN107, and it is commercially known as Cupronickel 70/30.

The product shall be produced by processes such as casting, extrusion, drawing, annealing, straightening, trimming, and other processes which may produce a seamless tube in the specified condition. The coppers and copper alloys shall be specifically furnished in any one of the following tempers: annealed, light-drawn, hard-drawn, or hard drawn and end annealed. Tubes for ferrule stock shall be annealed sufficiently to be fully crystallized. Some tubes are suggested to be subjected to a stress-relieving thermal treatment subsequent to straightening. The products shall be subjected to expansion, flattening, and residual stress tests. The tensile and expansion requirements for the products are specified in accordance with the temper designation. The products shall also be subjected to mercurous nitrate, ammonia vapor, Eddy-current, hydrostatic, and pneumatic tests.
