Copper Nickel Bolts consist of 90% copper and 10% nickel with small quantities of iron, manganese, and other elements. The composition provides superior resistance to corrosion, especially in seawater and acidic conditions. The mechanical properties are high tensile strength, usually between 550 and 800 MPa and good elongation (up to 40%). They also demonstrate remarkable stress corrosion cracking resistance and are very durable under both high-temperature and low-temperature conditions, making them particularly suitable for rigorous applications.

Copper Nickel bolts have far-reaching application in sea environment on account of having a fine property against corrosion, particularly seawater. The bolt finds their use in applications concerning ship building, offshore units, and seawater desalination plants. These are used in heat exchangers, power generation facilities, and chemical process industries as they are tolerant against high temperature as well as hostile chemicals. Copper Nickel’s strength, durability, and resistance to biofouling ensure that it is a popular material for use in situations where reliability is important in severe conditions.
