Nestled in the heart of Kinshasa, Sadiki Metals stands as a dedicated producer and trusted supplier of high-performance materials for demanding industries. We take particular pride in our expertise with Copper Nickel 7030 forgings, a material chosen for its exceptional resilience. Our focus is on delivering components that are not only robust but also meticulously crafted to meet the specific challenges faced by our clients, ensuring reliability in even the most corrosive and high-stress environments.
The strength of this alloy lies in its composition, primarily a blend of 70% copper and 30% nickel, often with small additions of iron and manganese for enhanced performance. This combination results in forgings with impressive mechanical properties, including high tensile strength and excellent ductility. They are renowned for their outstanding resistance to corrosion, particularly in marine settings, and their ability to withstand biofouling, making them a fundamentally tough and durable choice for critical applications.

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.
Because of this unique set of properties, Copper Nickel 7030 forgings are indispensable in sectors where failure is not an option. You will find them at work in the core components of shipbuilding, such as propeller shafts and seawater piping systems, where saltwater resistance is paramount. They are equally vital in offshore oil and gas platforms, desalination plants, and power generation facilities, consistently proving their worth by offering long-lasting service and reducing maintenance needs 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.
