Based in the industrious city of Hamilton, Will Sheetsandplates has built a strong reputation as a trusted manufacturer and supplier of high-performance metals. We take particular pride in our expertise with Copper Nickel 9010 circles, a specialty alloy we supply with unwavering commitment to quality. Our team understands the critical demands of your projects, which is why we ensure this material is available with precision and reliability, ready to meet the unique challenges faced by New Zealand’s diverse engineering and marine sectors.
The distinctive strength of Copper Nickel 9010 comes from its precise composition, primarily a blend of 90% copper and 10% nickel, with small but vital additions of iron and manganese. This careful recipe gives the alloy its exceptional resistance to corrosion, especially in aggressive saltwater environments where other metals might fail. Beyond its corrosion-fighting abilities, it also boasts excellent mechanical properties, including good ductility and thermal conductivity, making it not only tough but also surprisingly workable for fabrication into complex components.
