Punit Fasteners, a trusted manufacturer and supplier in Delhi, India, offers high-quality Copper Nickel 70/30 Bolts known for their strong corrosion resistance, especially in seawater and marine environments. Made from an alloy with 70% copper and 30% nickel, these bolts resist biofouling, stress corrosion cracking, and pitting. Copper Nickel 70/30 Bolts are perfect for marine, desalination, power plant, and chemical processing applications. Manufactured with care and tested to meet international standards, Punit Fasteners provides reliable, long-lasting fasteners for challenging conditions where performance and corrosion resistance matter.
Copper Nickel 70/30 Bolts contain 70% copper and 30% nickel, often with small amounts of iron and manganese to increase strength and corrosion resistance. These bolts have a tensile strength of around 300 to 500 MPa and show excellent resistance to seawater corrosion, erosion, and scaling. They also have good thermal conductivity and moderate strength at high temperatures. Copper Nickel 70/30 is non-magnetic and performs well under high-pressure and flow conditions. The alloy also welds easily and resists hydrogen embrittlement, making it reliable for marine and heat exchanger components.

To satisfy our clients needs by providing high quality products at competitive price as per the schedule and to maintain long term relationship with our clients.
Copper Nickel 70/30 Bolts are commonly used in shipbuilding, offshore platforms, heat exchangers, condenser systems, and seawater piping. Their strong resistance to saltwater corrosion makes them suitable for marine hardware, seawater intake systems, and underwater fasteners. These bolts are also found in power plants, especially in cooling systems dealing with saline or brackish water. In chemical processing and desalination plants, they can handle acidic and chlorinated environments. Their non-magnetic property suits naval and electronics applications. Copper Nickel 70/30 bolts are vital in setups where stability, conductivity, and long-term corrosion resistance in marine and chemical environments are necessary.
At Punit Fasteners, our Copper Nickel 70/30 Bolts are packed in a way that they reach the clients in the best condition possible.
