Rupal Metals, a reliable name in metal industries, is a prominent manufacturer and supplier of Copper Nickel 70/30 Forgings in Delhi, India. It is renowned for quality and customer care, and the company supplies premium-grade forgings designed with high corrosion resistance and mechanical properties. With sophisticated manufacturing units and a professional team, Rupal Metals makes every product precise and strong. Their Copper Nickel 70/30 Forgings find extensive demand in diversified industries for their high performance, dimensional accuracy, and reliability under harsh marine and industrial environments.
Copper Nickel 70/30 Forgings contain about 70% copper and 30% nickel along with trace amounts of iron and manganese to increase overall strength and corrosion resistance. These forgings are highly durable, resistant to seawater corrosion, and possess stable mechanical properties. They are generally characterized by tensile strength of 275–450 MPa and a yield strength of about 130 MPa. Having good thermal conductivity, high ductility, and a melting point close to 1170°C, the forgings are resistant to high pressure and temperature and therefore suitable for harsh and critical operating conditions.

The durability of Copper Nickel 70/30 forgings is ensured by excellent corrosion resistance, high tensile strength, superior weldability, resistance to seawater, anti-biofouling properties, and consistent alloy composition for enhanced performance.
Copper Nickel 70/30 forgings offer superior strength, enhanced corrosion resistance, improved material utilization, reduced waste, better grain structure, and higher durability compared to machining, making them ideal for demanding applications.
Compatible welding processes for Copper Nickel 70/30 forgings include TIG (GTAW), MIG (GMAW), and shielded metal arc welding (SMAW), ensuring strong joints, excellent corrosion resistance, and minimal thermal distortion.
The Copper Nickel 70/30 Forgings are widely employed in marine services like shipbuilding, condenser systems, and heat exchangers because they have resistance to saltwater and biofouling. These forgings are also used in chemical processing units, desalination plants, and offshore oil and gas platforms where corrosion resistance and durability are the main concerns. Due to their high thermal conductivity and strength in structure, they find applications in power generation equipment and pressure vessels. Due to their strength, reliability, and anti-corrosive properties, they are the most sought after for any kind of industrial and engineering application.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
