Copper Nickel 70/30 coil is a top-notch alloy crafted from 70% copper and 30% nickel. This blend offers fantastic resistance to corrosion, especially in seawater and other harsh environments, while also providing solid thermal and electrical conductivity. Its impressive durability, along with its ability to resist erosion and biofouling, makes it a go-to choice for marine, offshore, and industrial applications that demand long-lasting reliability and performance.
Typically, the composition of Copper Nickel 70/30 coil consists of 70% copper and 30% nickel, with a touch of iron and manganese added to boost strength and corrosion resistance. This alloy boasts good tensile strength, ductility, and flexibility, making it easy to work with for slitting, forming, and other processing tasks.
