What is Copper Nickel Square Bars?

Our Copper Nickel Square Bars, often from the 90/10 or 70/30 copper-nickel families, are engineered for exceptional performance. The inclusion of small amounts of iron and manganese gives these alloys their notable strength and superior resistance to corrosion, especially in aggressive marine environments. This composition results in a material that offers excellent tensile strength and outstanding ductility, allowing it to be easily fabricated and welded while maintaining its structural integrity under significant stress and varying temperatures.
