Copper Nickel Plates Sheets - UNS C71500

What are Copper Nickel Plates & Sheets - UNS C71500?

Put simply, Copper Nickel Plates & Sheets - UNS C71500 are flat metal products made using that specific 70/30 copper-nickel alloy recipe. The UNS C71500 designation signals the core components: copper (approx. 70%) and nickel (approx. 30%). However, the key to its enhanced capabilities lies in the deliberate additions of iron (Fe, usually 0.4-1.0%) and manganese (Mn, up to 1.0%). Far from being mere trace elements, these additions are crucial - they improve the alloy's strength and significantly boost its resistance to erosion-corrosion, a major factor in flowing seawater.

Key Attributes of C71500:

  • Strong Corrosion Defense: It performs exceptionally well against general corrosion, pitting, and crevice attack in seawater and salty or brackish water. Importantly, it also resists stress corrosion cracking (SCC), a vulnerability for some other metals.
  • Inherent Anti-Fouling: Like many copper-based materials, C71500 naturally discourages marine organisms from latching on. This is a big plus for maintaining heat transfer efficiency and flow in piping.
  • Good Strength & Formability: It offers respectable strength – noticeably more than the 90/10 CuNi grade (C70600), especially when temperatures climb. At the same time, it retains enough ductility for practical forming operations.
  • Works Well in the Shop: Standard fabrication techniques like bending, forming, welding, brazing, and soldering are all suitable for C71500. Welding, in particular, is generally straightforward.
  • Built for Demanding Service: This alloy comes into its own in situations involving higher temperatures, system pressures, and rapid fluid flow where erosion can be a significant problem.

Plate vs. Sheet – What's the Difference?

The main distinction is thickness:

  • Copper Nickel UNS C71500 Sheets: These are the thinner products, generally under 3/16 inch (around 4.76mm). They're often chosen when flexibility for forming complex shapes is needed or when minimizing weight is important.
  • UNS C71500 Copper Nickel Plate: This term applies to the thicker material, starting at 3/16 inch (4.76mm). Plate provides the necessary structural backbone for components like pressure vessel parts, sturdy tube sheets, and other applications needing greater rigidity.

USA Piping Solution supplies both Copper Nickel 70/30 Sheets and plates, helping you source the right starting form for your specific components.

Copper Nickel Plates & Sheets - UNS C71500 Specifications

Reliability starts with meeting the right standards. The Copper Nickel Alloy Sheets and plates provided by USA Piping Solution are produced to align with recognized international specifications. This practice ensures consistency and predictable performance in your critical systems.

Technical Specifications

Our inventory typically conforms to key standards including:

  • ASTM International:
    • B122 / B122M: The fundamental standard for C71500 plate, sheet, strip, and rolled bar.
    • B171 / B171M: A vital specification specifically covering plate and sheet intended for pressure vessels, condensers, and heat exchangers.
    • B151 / B151M: Details the requirements for rod and bar forms.
    • B432 / B432M: Defines C71500 when used as a protective cladding layer over steel plate.
  • ASME (Boiler and Pressure Vessel Code):
    • SB122 / SB171 / SB151: These are the corresponding ASME versions, enabling use in code-stamped construction.
  • Military (MIL-SPEC):
    • MIL-C-15726F: A frequently cited standard for C71500 in various forms, often used for naval procurement.
  • Other Widely Used Standards:
    • DIN 2.0882 (German std. designation: CuNi30Mn1Fe)
    • EN CW354H (European Norm designation: CuNi30Mn1Fe)
    • BS 2875 CN107 (An older British standard sometimes still seen)
    • SAE J461, J463 (Society of Automotive Engineers standards covering copper alloys)

Meeting these established benchmarks provides a solid foundation for material selection and performance expectations.

Chemical Composition and Mechanical Properties

What makes C71500 perform the way it does? It comes down to its precise chemical balance and the resulting physical strength characteristics. USA Piping Solution ensures that our materials align with these critical parameters.

Chemical Composition (Typical, Weight %)

Looking at the typical ingredients:

Element Symbol Content Range (%) Nominal (%) Role in the Alloy
Copper Cu Remainder ~69.5 The primary base metal
Nickel Ni 29.0 - 33.0 30.0 Key to corrosion resistance
Iron Fe 0.40 - 1.0 ~0.7 Improves erosion performance
Manganese Mn up to 1.0 ~0.8 Aids processing, adds strength
Lead Pb up to 0.05 - Limited as an impurity
Zinc Zn up to 1.0 - Limited as an impurity

(Note: "Rem" means Remainder. Specific limits can have slight variations depending on the standard being followed.)
The controlled amounts of Nickel and Iron are particularly important for achieving good service life in marine conditions.

Mechanical Properties (Typical, Annealed Condition)

These values give insight into the material's strength and ductility:

Property Typical Value (Imperial) Typical Value (Metric) What It Indicates
Tensile Strength, Ultimate ~60 ksi ~414 MPa Maximum pulling stress
Tensile Strength, Yield ~25 ksi ~172 MPa Stress point for permanent set
Elongation in 2" ~40 % ~40 % How much it stretches before break
Hardness, Rockwell B ~60 HRB ~60 HRB Resistance to surface indentation
Modulus of Elasticity ~22,000 ksi ~152 GPa Material's inherent stiffness

(Note: These represent typical values for the soft, annealed condition. Cold working will increase strength and hardness but reduce elongation. Always refer to the specific Material Test Report (MTR) for guaranteed minimums for your material lot.)
This balance allows C71500 to be formed effectively when annealed, while other tempers provide higher strength if needed.

Types and Variations of Copper Nickel Plates & Sheets

While UNS C71500 identifies the alloy itself, the product you order will also depend on form, condition, and finish:

  • Plate or Sheet: As covered, thickness is the main differentiator. Sheets (< 3/16") are thinner and more formable; Plates (≥ 3/16") are thicker, offering structural integrity.
  • Temper (Material Condition):
    • Annealed (O61): The softest condition, offering maximum ductility. Ideal if significant forming or welding is planned. Common for both forms.
    • Hot Rolled (M20): A frequent starting condition for plates, providing a good baseline combination of properties.
    • Cold Rolled (H-Tempers): Used mainly to strengthen sheets (e.g., H02 - Half Hard). This makes the material harder but less easy to form.
  • Surface: The standard finish comes from the rolling process. If you need a specific finish like polished or brushed, let us know.
  • Clad Option: It's possible to get UNS C71500 Copper Nickel Plate bonded to a steel base plate (following ASTM B432). This combines C71500's corrosion barrier with the cost-effectiveness and strength of steel backing.

The USA Piping Solution team can help you determine which specific product configuration best matches your project's needs.
