70/30 Cu-Ni Threaded Rods

The composition of Copper Nickel 7030, also known as CuNi 70/30, is precisely balanced with approximately 70% copper and 30% nickel, along with small additions of iron and manganese. This specific blend is what grants the alloy its remarkable strength and corrosion resistance. Mechanically, these bars and rods are tough and ductile, offering excellent tensile strength. They perform superbly in marine and industrial settings because they are highly resistant to biofouling and the corrosive effects of saltwater, making them a robust, long-lasting material choice.
