Copper Nickel Nuts are made primarily from a balanced blend of copper and nickel, with controlled additions of iron, manganese, and other strengthening elements. This composition provides excellent resistance to seawater corrosion, stress cracking, and biofouling. They offer good mechanical strength, toughness, and stability across varying temperatures. These nuts maintain their ductility and structural integrity even under continuous exposure to moisture, making them suitable for high-pressure and high-temperature applications. Their combination of strength, corrosion resistance, and thermal stability ensures long-lasting performance in harsh marine and industrial environments.
