From the heart of Hamilton, New Zealand, Will Sheetsandplates proudly provides industry with the robust reliability of Copper Nickel 7030 coil. For decades, our focus has been on supplying high-performance materials built to withstand the most challenging environments. This particular alloy, often called Cupronickel 70/30, is a specialist material we supply to clients who demand exceptional resistance to corrosion, especially in marine and industrial settings where longevity and performance are absolutely critical. We understand that your projects depend on quality materials, which is why we ensure our stock meets the highest standards.
The composition of this alloy is a precise blend of approximately 70% copper and 30% nickel, with small but important additions of iron and manganese. This specific formulation is what gives the material its renowned strength and durability. In practical terms, this translates to excellent mechanical properties, including high tensile strength and impressive resistance to both erosion and corrosion. It’s a tough, ductile material that can be easily fabricated and welded, making it a versatile and dependable choice for engineers and fabricators working on long-lasting projects.

Copper nickel 70/30 coils and Slitting Coil offer many benefits including excellent resistance to seawater corrosion, making them ideal for marine applications. Their excellent resistance to biofouling, oxidation and stress corrosion cracking makes them durable in harsh environments. The alloy provides excellent thermal and electrical conductivity along with excellent formability and weldability. Copper nickel 70/30 coils are strong yet flexible, have high tensile and yield strengths, making them suitable for use in heat exchangers, desalination plants and chemical processes along with continuous operation at extreme temperatures and provides lower maintenance over time.
The unique properties of Copper Nickel 7030 coil make it the go-to material for critical applications, particularly where saltwater is a constant factor. You will find it extensively used in shipbuilding for condenser tubes, heat exchangers, and seawater piping systems. Beyond the sea, its applications extend to power generation plants, offshore oil and gas platforms, and desalination facilities. Essentially, any situation that demands a material which can aggressively resist biofouling and corrosion while maintaining structural integrity over decades is a perfect fit for this exceptionally durable alloy.
