With a variety of options available—including hex nuts, lock nuts, cap nuts, and wing nuts—Fajar Metals guarantees that all products comply with international standards like ASTM B151 and DIN specifications. Their remarkable durability and mechanical stability make Cu-Ni 90/10 nuts the go-to choice for secure fastening in challenging and corrosive environments.
Copper Nickel 90/10 Nuts are made up of 90% Copper (Cu) and 10% Nickel (Ni), with trace amounts of Iron (Fe) and Manganese (Mn) included to boost mechanical strength and corrosion resistance. These nuts deliver a tensile strength ranging from 275 to 350 MPa, a yield strength of 105 to 150 MPa, and impressive ductility, even in high-salinity or fluctuating temperature conditions. They are highly resistant to chloride stress corrosion, biofouling, and oxidation, ensuring they maintain their integrity during long-term marine and industrial use. Their excellent machinability and thermal conductivity also make them compatible with various metal and non-metal components.
