Copper Nickel Fasteners Manufacturer in India
Sawariya Metal Industries is a manufacturer, supplier, stockist and exporter of Copper Nickel Fasteners in different sizes, grades, specifications and finishes for industrial and engineering applications.
Copper Nickel Fasteners are mechanical joining components such as bolts, nuts, studs, screws and washers used to assemble flanges, structures, machinery and equipment.
Copper nickel (Cu-Ni) alloys such as 90/10 and 70/30 offer excellent resistance to seawater corrosion and biofouling, combined with good thermal conductivity and fabricability.
Typical applications for Copper Nickel Fasteners include marine engineering, shipbuilding, desalination, offshore platforms, heat exchangers, condensers, seawater piping, power generation and general engineering.
Key Features of Copper Nickel Fasteners
Seawater Corrosion Resistance
Excellent performance in seawater and marine environments.
Biofouling Resistance
Natural resistance to marine biofouling.
Thermal Conductivity
Good heat-transfer properties for exchangers and condensers.
Easy Fabrication
Good formability and weldability.
