Cupro Nickel Fasteners
Cupro Nickel Fasteners are specifically engineered to withstand corrosion in challenging environments, particularly in marine and underwater applications where saltwater exposure is a concern. Composed of a copper-nickel alloy, these fasteners offer exceptional resistance to corrosion, outperforming traditional steel or iron-based fasteners. This makes them an excellent option for use in environments where corrosion is likely to be problematic.
