CW354H is a Euro Norm standard copper-nickel bar product produced to BS EN 12163.
CW354H is renowned for improved performance compared to 90/10 copper-nickel alloy, particularly in harsher application environments such as high-velocity water. Strength is also marginally superior while promoting good toughness. Like all copper-nickel alloys, CW354H offers excellent corrosion resistance with additional attractive characteristics, including good pitting and bio-fouling resistance (although 90/10 copper nickel offers superior resistance). The product also has a moderately high melting point and low electrical conductivity and provides excellent mechanical properties at low temperatures.
The alloy is easy to weld, machine and form by conventional methods. The chemical Euro Norm designation for this material is CuNi30-Mn1Fe.
CW354H is ideal for commercial applications in the marine sector, including above-sea and subsea operations. Heat exchangers, propeller bore sleeves, subsea pipes and pump/valve components all utilise CW354H copper-nickel alloy.
We stock CW354H in solid round bars in close incremental sizes. We also provide bar-cutting services via our bulk central warehouse in Biggleswade.
