What are Cupro Nickel fasteners, and what makes them unique in fastening
solutions?
Cupro Nickel Fasteners are
specialized fastening solutions made from a copper-nickel alloy. This alloy typically
contains around 90% copper and 10% nickel, although the precise composition may vary. Their
exceptional corrosion resistance sets Cupro Nickel fasteners apart from other fasteners,
especially in marine and high-moisture environments.

What are the common applications for Cupro Nickel fasteners, and why are they
preferred in those industries?
Cupro Nickel fasteners find common applications in industries where
corrosion resistance and durability are paramount. One such industry is shipbuilding, where
these fasteners are widely used in marine environments. The high resistance to saltwater
corrosion exhibited by Cupro Nickel fasteners makes them an ideal choice for critical ship
components, such as hull structures, propellers, and piping systems. Similarly, in offshore
oil and gas installations, where exposure to harsh seawater conditions is constant, Cupro
Nickel fasteners are favoured for their ability to withstand corrosion, ensuring the
integrity and safety of the structures.
Another industry that benefits from Cupro Nickel fasteners is desalination plants, where the
high salinity levels and aggressive chemical environments demand corrosion-resistant
solutions. Cupro Nickel fasteners excel in these settings, providing longevity and
reliability. Additionally, Cupro Nickel fasteners are used in chemical processing plants,
power generation facilities, and even in the automotive and aerospace sectors, where their
resistance to corrosion and excellent mechanical properties make them a preferred choice for
critical fastening applications.
Manufacturing Process Of Cupro Nickel Fasteners
Forging
Forging is a manufacturing process that involves shaping metal through
the application of force.
Machining & Drilling
Both machining and drilling play crucial roles in the manufacturing of
components across a wide range of industries.
Heat Treatment
Heating the metal to a temperature below the critical range and then slow
cooling
Quality Control & Marking, Identification
Quality control and marking are essential aspects of manufacturing and
production processes across metal industries.
Packaging and Delivery
To reach their destination in pristine condition, we employ careful
packaging techniques.
