For over a decade, Junaid Metals has stood as a cornerstone of industrial supply in Manama, Bahrain, renowned for our unwavering commitment to excellence. We take particular pride in our expertise with Copper Nickel 7030 Forgings, a premium material trusted in the most demanding environments. Our process, from sourcing raw materials to final quality assurance, is meticulously managed to deliver components that offer exceptional strength and legendary corrosion resistance, ensuring the long-term reliability of critical systems for our clients across the region and beyond.
The strength of Copper Nickel 7030, or CuNi 70/30, lies in its specific composition and resulting properties. This alloy is predominantly copper, alloyed with approximately 30% nickel and small but vital additions of iron and manganese. This formula grants it outstanding mechanical properties, including high tensile strength and excellent ductility. Most importantly, it develops a remarkable resistance to corrosion, especially in marine and saline atmospheres, and maintains its integrity across a wide range of temperatures, making it a truly robust engineering material.

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.
These forgings are indispensable in industries where failure is not an option. You will find them at the heart of marine engineering, used for essential components like pump shafts, valve bodies, and propeller systems that constantly battle seawater. The offshore oil and gas sector relies on them for piping systems and fittings on platforms and rigs. Their excellent biofouling resistance is also crucial for desalination plant heat exchanger tubes and condenser components, ensuring clean water production and the efficient operation of power generation facilities worldwide.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
