Surging high-end demand for copper-nickel alloys has made C70600 tubing the “golden material” for offshore engineering.
In the first quarter of 2026, global demand for copper-nickel alloy (C70600/BFe10-1-1) in the offshore engineering and shipbuilding sectors surged by 42% year on year. As a flagship grade of 90/10 copper-nickel alloy, C70600 is favored for its outstanding performance—namely, an annual corrosion rate of less than 0.025 mm in 3.5% seawater, excellent resistance to biofouling, and high thermal conductivity—making it the material of choice for LNG vessel condensers, desalination units, and piping systems on deepwater platforms. Leading domestic manufacturers are operating at full capacity, with their products certified by classification societies such as DNV and ABS and exported in bulk to Europe and Southeast Asia. Industry analysts project that, driven by the expansion of the “blue economy,” the market for copper-nickel alloy tubing will exceed RMB 8.5 billion in 2026.
