From the heart of Hamilton, New Zealand, Will Sheetsandplates stands as your dedicated partner for robust and corrosion-resistant marine materials. We proudly supply the industry-renowned Copper Nickel 90 10 Angle, a product engineered for durability in the harshest environments. Forged from our commitment to quality and local expertise, this high-performance angle is a cornerstone for critical projects, ensuring longevity and reliability where it matters most for engineers and fabricators across the country and beyond.
This specific alloy, often called cupronickel, combines approximately 90% copper with 10% nickel, creating a material with a distinct silvery-gold appearance. That blend is the secret to its strength, offering excellent mechanical properties including good tensile strength and impressive ductility. It’s naturally resistant to biofouling and maintains its toughness even in sub-zero temperatures. Most importantly, it possesses an exceptional ability to withstand corrosion from saltwater, making it a premier choice for any application where exposure to the sea is a constant factor.

Copper nickel 90/10 angles provide excellent corrosion resistance, especially in marine and coastal environments, due to resistance to sea corrosion, biocorrosion and stress corrosion cracking Their high strength-to-weight ratio makes them strong and capable reliable in construction applications. The alloys are easy to fabricate, weld and fabricate, increasing design flexibility. It also has excellent thermoelectric conductivity, ideal for heat exchangers and piping. When combined with iron and manganese, it resists corrosion and shock from turbulent water. A copper nickel 90/10 face ensures long, low-maintenance service, reducing overall operating costs.
You’ll find this versatile angle hard at work in shipbuilding and repair, forming essential parts of hulls and deck structures. Its resistance makes it ideal for offshore oil and gas platforms, desalination plants, and power generation condensers. Beyond major industry, it’s also perfect for coastal architecture, maritime fittings, and any engineering project requiring a material that can confidently stand up to demanding marine conditions, ensuring structures and vessels remain secure and functional for years to come.
