UNS C70600 copper nickel alloys are used in areas where stainless steel cannot be used due to chloride stress-corrosion cracking and in other parts requiring high levels of corrosion resistance. These alloys are also used as machined and forged valve and pump parts that are utilized for seawater services.
COPPER NICKEL CORROSION RESISTANCE
Copper alloys have very good resistance to seawater, brine water, organic compounds, salts, diluted non-oxidizing acids, and more. CuNi 90/10 (C70600 & C7060X) is a Copper Nickel Iron alloy with a small content of manganese which allows excellent resistance to sea- and brakish water. Of all commercial coper alloys, CuNi 70/30 (C71500) offers the best resistance to aqueous corrosion. It is resistant to acid solutions and highly resistant to stress corrosion cracking, and impingement corrosion. In addition, CuNi70/30 offers a greater strength for higher pressures.
COPPER NICKEL HEAT RESISTANCE
The hot strength of copper increases with only a small addition of nickel. By adding iron, mechanical properties are improved, not only at room temperature, but also at elevated temperatures. 10% Ni. CuNi10Fe1Mn, for example, can be used in pressure vessel construction up to 300°C, CuNi30Mn1Fe up to 350°C. Above these limit temperatures, strength drops markedly, particularly the creep strength and creep strain limit.
COPPER NICKEL HEAT TREATMENT
In general, heat treatments are only used with Cu-Ni alloys for soft annealing and stress relieving. Temperatures for recrystallisation annealing can vary over wide limits between about 620 and 900°C, depending on degree of cold work, nickel content and additional constituents. High temperatures are associated with short annealing times (continuous annealing) and low temperatures with long annealing times (static annealing). Stress-relief annealing is carried out at 280 to 500°C. It is advisable to anneal excluding air or in a slightly reducing atmosphere, to avoid the pickling that is required with air-containing annealing atmospheres.
