Sadiki Metals, based in Kinshasa, Congo, stands out as a top manufacturer and supplier of Copper-Nickel Flat Bars. Their products are crafted with care for marine, industrial, and engineering uses. Thanks to state-of-the-art production facilities and rigorous quality checks, Sadiki Metals guarantees that each flat bar adheres to international standards for corrosion resistance, strength, and precision. Catering to sectors like marine engineering, chemical processing, oil and gas, and industrial fabrication, the company delivers dependable Copper-Nickel solutions throughout Central Africa. Known for their reliability, technical know-how, and prompt delivery, Sadiki Metals is a go-to source for high-performance Copper-Nickel Flat Bars in challenging settings.
Copper-Nickel Flat Bars usually come in 70/30 (70% Cu, 30% Ni) or 90/10 (90% Cu, 10% Ni) alloy blends, often with small amounts of iron and manganese added to boost strength and resistance to seawater corrosion. These alloys are particularly good at resisting biofouling, stress corrosion, and erosion, making them perfect for tough marine conditions. Their mechanical properties include a tensile strength ranging from 275 to 550 MPa, yield strength between 100 and 300 MPa, and elongation of 30 to 50%, depending on the specific grade and temper. This alloy offers a great mix of ductility, weldability, and corrosion resistance, ensuring a long service life and dependable structural integrity.

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.
Copper-Nickel Flat Bars find a wide range of applications where outstanding corrosion resistance, strength, and durability are essential in marine and industrial settings. They’re perfect for shipbuilding, seawater piping systems, heat exchangers, condenser plates, and desalination plants. In the chemical and oil & gas sectors, they’re commonly used for pumps, valves, and fittings because of their ability to withstand acids and saline solutions. Additionally, Copper-Nickel Flat Bars are utilized in offshore structures, power generation, and HVAC systems, proving their versatility and reliability across various demanding environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
