This specification establishes the requirements for plates, sheets, and circles cut from plates and sheets made of UNS C36500, C44300, C44400, C44500, C46400, C46500, C61300, C61400, C63000, C63200, C70600, C70620, C71500, C71520, or C72200 copper alloy. These materials are recommended for use in pressure vessels, condensers, and heat exchangers. The materials are manufactured by either hot rolling or forging and finished by such cold working and annealing to produce products of the required dimensions and properties. Tempers available under this specification are as hot rolled and hot rolled and annealed. The products manufactured for ASME Boiler and Pressure Vessel code applications must be certified to the hot rolled and annealed temper while all other products can either have hot rolled or hot rolled and annealed temper.

Large-scale factory production of solid copper sheet
Applications
Offshore: Copper-nickel alloys specified in ASTM B171 have excellent resistance to seawater corrosion and are therefore used in a wide range of offshore applications. This includes ship hulls, offshore platforms and piping systems for seawater intake and treatment.
Heat Exchangers and Condensers: These materials are commonly used in the manufacture of heat exchangers and condensers, especially in environments where corrosion resistance is critical. Their thermal conductivity makes them ideal for efficient heat transfer in a variety of industrial processes.
Desalination plants: In desalination plants, copper-nickel alloys are used for evaporators, heat exchangers and piping. The corrosion resistance of copper-nickel alloys is critical when dealing with the corrosive conditions present in seawater and desalination processes.
