Welcome to Maduka Metals, your trusted partner in Abuja for high-performance industrial materials. We specialize in supplying and manufacturing robust Copper Nickel 9010 forgings, engineered to meet the demanding challenges of modern industry. Our commitment is to provide Nigerian businesses with locally accessible, top-tier components that combine exceptional durability with superior corrosion resistance, ensuring your projects are built on a foundation of reliability and quality you can count on.
The composition of these forgings is a precise 90% copper and 10% nickel alloy, often with carefully controlled additions of iron and manganese. This specific blend is what grants the material its remarkable strength and toughness. Mechanically, it performs superbly under stress, offering excellent tensile strength and good ductility. It maintains these properties across a wide range of temperatures, making it a wonderfully resilient choice for components that face both high pressures and thermal fluctuations.

Copper Nickel 90/10 forgings may face challenges like higher cost, susceptibility to galvanic corrosion in specific environments, and limited availability in some sizes, requiring precise processing and material sourcing.
Common welding processes compatible with Copper Nickel 90/10 forgings include TIG (GTAW), MIG (GMAW), and SMAW. Proper filler materials, such as CuNi rods, ensure strong, corrosion-resistant welds for optimal performance.
Durability of Copper Nickel 90/10 forgings is ensured by factors like corrosion resistance, proper heat treatment, precise manufacturing, adequate welding techniques, and protection against galvanic corrosion in marine and industrial environments.
You’ll find Copper Nickel 9010 forgings hard at work in some of the most challenging environments. They are the preferred choice for critical marine applications, such as shipbuilding components, offshore platform fittings, and seawater piping systems where their resistance to saltwater corrosion is invaluable. Beyond the sea, they are essential in the oil and gas industry for valves and pumps, in power generation plants for condenser tubes, and in desalination facilities, proving their versatility and steadfast performance wherever reliability is non-negotiable.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
