These nuts are produced using high-quality Cu-Ni alloys like 90/10 and 70/30 grades. Our copper nickel nuts have extensive applications in marine, desalination, and heat exchanger industries. Built for extreme environments, they possess superior mechanical strength, long-term durability, and resistance to stress corrosion cracking. Mira Fasteners provides standard and custom-sized copper nickel nuts produced to ASTM, ASME, and global standards for severe marine and industrial applications.
Copper Nickel Nuts typically contain 90% copper and 10% nickel (90/10) or 70% copper and 30% nickel (70/30), along with small amounts of iron and manganese for enhanced strength. These nuts provide tensile strength between 350–500 MPa and are highly ductile and corrosion-resistant. They maintain mechanical integrity under high-pressure and saline conditions, offering excellent resistance to erosion and cavitation. Cu-Ni nuts are also non-magnetic and suitable for cryogenic to moderately high-temperature environments.
