Copper Nickel 90/10 Bolts are primarily made up of Copper (Cu – about 90%) and Nickel (Ni – around 10%), with small amounts of Iron (Fe) and Manganese (Mn) added to enhance overall strength and corrosion resistance. This alloy is known for its exceptional resistance to seawater corrosion, erosion, and stress corrosion cracking. Typical mechanical properties include a tensile strength ranging from 250 to 350 MPa, yield strength between 100 and 150 MPa, and good elongation, which ensures ductility and toughness in both marine and industrial environments. These bolts deliver reliable mechanical performance even under fluctuating temperatures and high-salinity conditions.
