What is Copper Nickel Hollow Bar?

The composition of our Copper Nickel Hollow Bar typically features a 90/10 or 70/30 copper-nickel blend, often with carefully added elements like iron and manganese to significantly enhance its performance. This specific alloying results in outstanding mechanical properties, including excellent tensile strength and remarkable resistance to corrosion, particularly in harsh marine and chemical settings. Its natural anti-fouling characteristics and superb ductility make it not only strong but also surprisingly easy to fabricate and weld for complex projects.
