For Hamilton-based manufacturers and engineers seeking exceptional marine performance, Will Sheetsandplates stands as your trusted local source for high-quality materials. We take pride in supplying our community with reliable products like our Copper Nickel 7030 Foil, a specialist alloy designed to withstand some of the harshest environments. Sourced for its superior durability, this foil offers a robust solution for projects demanding long-term resistance to corrosion, making it an ideal choice for innovative applications right here in New Zealand and beyond.
The makeup of this alloy is a carefully balanced composition of approximately 70% copper and 30% nickel, which gives it a distinct set of advantages. This blend results in a material with excellent mechanical properties, including good tensile strength and impressive formability, allowing it to be easily worked into complex shapes. It also maintains excellent ductility, meaning it can bend and flex without fracturing. Perhaps most importantly, it possesses a remarkable resistance to stress-corrosion cracking, ensuring integrity under pressure in demanding service conditions.
