Copper Nickel Screws are primarily made from copper (70–90%) and nickel (10–30%), with small amounts of iron and manganese to enhance strength and corrosion resistance. These screws offer tensile strength ranging from 350–550 MPa and exhibit excellent ductility, toughness, and fatigue resistance. Their composition provides superior resistance to pitting, crevice corrosion, and biofouling, making them ideal for chloride-rich and seawater environments. Copper Nickel Screws maintain stability under temperature fluctuations, ensuring long-term reliability and performance in harsh industrial and marine conditions.
