Durability: Cupro Nickel 70/30 hex nuts are built to last. Their high tensile strength and ductility ensure they can withstand the stresses and strains of various industrial operations. This durability translates to longer service life, reducing maintenance and replacement costs.

Heat Resistance: Cupro Nickel 70/30 maintains its mechanical properties in a wide temperature range, from sub-zero temperatures to high heat. This versatility makes it suitable for applications where temperature fluctuations are common, such as heat exchangers, condensers, and HVAC systems.

Anti-Fouling Properties: The anti-fouling properties of Cupro Nickel 70/30 are particularly beneficial in seawater environments. Its resistance to biofouling, which includes the growth of barnacles and other marine organisms on surfaces, minimizes the need for frequent cleaning and maintenance. This makes it an environmentally friendly choice, reducing the use of antifouling coatings.

Machinability: Cupro Nickel 70/30 is relatively easy to machine and fabricate, which simplifies the manufacturing process. Hex nuts made from this alloy can be precisely crafted to meet specific design requirements.
