Welcome to Maduka Metals, your trusted partner for industrial solutions right here in Abuja. We specialize in providing high-quality, durable materials tailored to Nigeria’s demanding environments, and our Copper Nickel 7030 forgings are a prime example. These robust components are engineered for resilience, offering exceptional performance where it matters most. We understand the critical nature of reliable supply chains, which is why we are committed to delivering not just a product, but a dependable foundation for your most important projects, backed by local expertise and unwavering support.
Copper Nickel 7030, also known as cupronickel 70/30, is an alloy with a remarkable blend of approximately 70% copper and 30% nickel. This specific composition gives it a distinct set of advantages, including outstanding resistance to corrosion, especially in seawater and marine atmospheres. Mechanically, these forgings are incredibly tough; they possess high tensile strength, excellent ductility, and superior thermal conductivity. This combination ensures they can handle significant pressure, resist wear over time, and perform reliably in both high and low-temperature settings, making them a fundamentally sound engineering choice.

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 strength of Copper Nickel 7030 forgings makes them indispensable in challenging environments. They are the go-to choice for critical components in the marine industry, such as propeller shafts, pump bodies, and valves on ships and offshore platforms. Beyond the sea, you’ll find them in desalination plants, power generation facilities, and chemical processing equipment where corrosion is a constant threat. Essentially, any application that demands long-lasting performance against aggressive elements benefits from the proven reliability of these forgings, ensuring systems run smoothly and safely for years.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
