CW352H Copper Nickel Bar

For marine & hygienic environments

CW352H is often used in intensive care units as a 'hygienic touch' material.

CW352H is a Euro Norm copper nickel alloy that we stock in solid round bars. The chemical and mechanical properties of the alloy are to BS EN 12163.

Our stocked solid round bar products come in various diameters, available in closer increments. Stocking bars in this way are attractive because often, we have material stock available in sizes which negate the need for you to machine the material down. Ultimately, procuring materials to your size requirements saves you time and money.


CW352H is essentially an alternative specification for 90/10 copper-nickel alloy comprising 90% copper (Cu) and 10% nickel (Ni). Trace elements, including iron and manganese, are included in the production mix. CW325H offers a balance of performance characteristics, making the engineering raw material highly suitable for applications in the oil, gas, petrochemical and marine hardware sectors. CW354H offers slightly better tensile strength compared to CW325H.

CW352H benefits from excellent corrosion resistance and also good resistance to hydrogen embrittlement. With moderate strength, high toughness and high ductility, the material is highly effective at resisting corrosion in saltwater environments. Effective resistance to biological fouling is also a benefit, a constant problem in the offshore and marine sectors. Excellent anti-microbial characteristics also result in an alloy popular in hygienic environments such as hospitals and clean rooms.
