Copper Nickel Bolts are composed primarily of copper (around 70–90%) and nickel (10–30%), with small additions of iron and manganese to improve strength and corrosion resistance. These bolts exhibit tensile strength ranging from 350–550 MPa and possess excellent ductility and toughness. Their composition provides exceptional resistance to pitting, crevice corrosion, and biofouling, making them highly suitable for seawater and chloride-rich environments. Copper Nickel Bolts maintain stability under varying temperatures, ensuring reliable long-term performance in harsh industrial and marine conditions.
