Welcome to Maduka Metals, your trusted partner for industrial solutions right here in Abuja. We specialize in the manufacturing and supply of high-performance copper nickel forgings, bringing robust and reliable components directly to Nigeria’s vibrant industrial sector. Our commitment is to provide locally sourced quality that meets the most demanding standards, ensuring your projects benefit from superior materials and dependable service without the complexities of international supply chains.
Our copper nickel forgings, often referred to as Cu-Ni or 90/10 alloys, are engineered for exceptional performance. The precise copper-nickel composition grants these components outstanding resistance to corrosion, especially in saline environments, while maintaining excellent mechanical strength and toughness across a wide range of temperatures. This combination makes them incredibly durable and long-lasting, even under the stress of high-pressure applications.

Compatible welding processes for copper-nickel forgings include TIG (Tungsten Inert Gas), MIG (Metal Inert Gas), and Stick welding. These methods ensure strong, durable joints while preserving the material's properties.
Copper-nickel forgings are commonly used in marine, aerospace, chemical processing, power generation, oil and gas, desalination, and plumbing industries due to their corrosion resistance, strength, and durability in harsh environments.
Factors ensuring the durability of copper-nickel forgings include proper alloy composition, effective heat treatment, corrosion resistance, precise forging processes, and protective coatings, all contributing to strength, reliability, and long-term performance.
These remarkable properties make copper nickel forgings indispensable across several key industries. They are the preferred choice for critical marine applications, including seawater piping systems, pumps, and valves on ships and offshore platforms. Beyond the sea, you’ll find them in the chemical processing plants for handling corrosive fluids, in power generation for condenser tubes, and in oil and gas infrastructure, where their reliability ensures safe and efficient operations in challenging conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
