Cupro Nickel 70/30 Stud Bolts, also known as Cu-Ni 70/30, is a copper-nickel alloy renowned for its excellent corrosion resistance, thermal stability, and durability. When used in the fabrication of stud bolts, Cu-Ni 70/30 offers a dependable fastening solution for a variety of applications. Stud bolts are threaded rods that are commonly used to secure and fasten components in diverse industries, and Cu-Ni 70/30 stud bolts offer several key advantages:
Corrosion Resistance: Cupro-Nickel 70/30 is highly resistant to corrosion, particularly in marine environments where it is exposed to seawater and brine. This makes it an ideal material for stud bolts in offshore and shipbuilding applications.
Thermal Stability: Cu-Ni 70/30 maintains its mechanical properties over a wide temperature range, making it suitable for applications in both cryogenic and high-temperature environments. This stability is crucial for ensuring the long-term integrity of the fastening system.
Durability: The alloy's excellent resistance to erosion, cavitation, and biofouling further enhances the durability of Cu-Ni 70/30 stud bolts. This makes them suitable for applications in seawater systems, heat exchangers, and other critical components.
Biocompatibility: Cu-Ni 70/30 is also biocompatible, making it appropriate for use in medical equipment and devices where it may come into contact with biological fluids or tissues.
Ease of Fabrication: Cupro-Nickel 70/30 is a readily machinable and weldable material, allowing for ease of fabrication into stud bolts of various sizes and configurations.
