Nestled in the heart of Hamilton’s industrial landscape, Will Sheetsandplates has built a strong reputation for supplying top-tier materials to New Zealand’s most demanding projects. We take particular pride in our Copper Nickel Coil, a specialized marine-grade alloy renowned for its exceptional ability to withstand harsh, corrosive environments. Our team understands that reliable material is the backbone of any successful build, which is why we ensure our clients receive nothing but the highest quality coil, backed by deep industry knowledge and a commitment to local service.
This marine-grade alloy, often known as cupronickel, is primarily composed of copper with a significant nickel content, alongside carefully balanced additions of iron and manganese. This specific formulation is the secret to its outstanding performance, granting it superior resistance to seawater corrosion and exceptional biofouling resistance. Mechanically, the coil offers impressive strength and durability, remaining highly ductile and easy to fabricate into complex components. It also retains excellent thermal conductivity, making it a versatile choice for both structural and heat exchange applications.

Copper-nickel coil offer many advantages including exceptional corrosion resistance, especially in sea water and harsh marine environments. They are highly robust, resistant to biofouling, and store energy over a wide temperature range. The excellent thermoelectric conductivity of the alloy makes it ideal for heat exchangers and electrical components. Copper-nickel sockets also exhibit excellent formability, enabling complex shapes without compromising integrity. Properties that resist stress corrosion cracking and oxidation ensure long-term performance in complex applications such as shipbuilding, desalination plants and chemical processing, making it cost-effective and portable to it in the long run
The primary use for our Copper Nickel Coil is within the marine industry, where it is absolutely essential for critical systems such as shipbuilding and offshore platforms. You’ll find it fabricated into seawater piping, condensers, heat exchangers, and desalination units, where its longevity is paramount. Beyond the sea, its unique properties are invaluable in power generation plants for condenser tubes, and in the chemical and petroleum industries for processing equipment that handles corrosive substances. Its reliability makes it the go-to material for any application where failure is not an option.
