Santner Nickel Alloys, located in Hamilton, New Zealand, stands out as a leading manufacturer and supplier of Copper Nickel Coils, delivering top-notch solutions for industrial, marine, and chemical applications. These coils are crafted to offer outstanding corrosion resistance, mechanical strength, and thermal conductivity, making them perfect for tough operational settings. With a focus on precision, Santner’s Copper Nickel Coils guarantee consistent thickness, an excellent surface finish, and dependable performance. Commonly found in heat exchangers, condensers, piping systems, and marine equipment, these coils are built for durability and longevity. Santner Nickel Alloys merges cutting-edge engineering with rigorous quality standards to produce coils that align with international specifications and industrial needs.
Copper Nickel Coils are generally made up of 90% copper and 10% nickel (CuNi 90/10) or 70% copper and 30% nickel (CuNi 70/30), with small amounts of iron and manganese added to boost strength and corrosion resistance. They showcase remarkable tensile strength, ductility, and fatigue resistance, all while maintaining high thermal conductivity and dimensional stability. These characteristics enable the coils to endure pressure, thermal cycling, and harsh environments. The blend of flexibility and mechanical strength makes Copper Nickel Coils ideal for forming, bending, and fabrication processes without sacrificing their performance in industrial, marine, or chemical settings.
