Welcome to Sadiki Metals, your trusted partner in Kinshasa for superior industrial materials. We take pride in manufacturing and supplying high-performance Copper Nickel 955 bars and rods, crafted to meet the rigorous demands of modern engineering. As a local leader, we are committed to providing reliable, high-quality products that support the growth and innovation of various industries right here in Congo and beyond, ensuring our clients have access to the durable materials they need for their most critical projects.
Copper Nickel 955, often called CuNi 95/5, is an alloy known for its excellent resistance to seawater corrosion. Its composition is primarily copper, with about 5% nickel and small additions of iron and manganese, which significantly enhance its strength and durability. This combination results in impressive mechanical properties, including high tensile strength and exceptional ductility. These bars and rods are also highly resistant to biofouling and erosion, making them incredibly tough and long-lasting even in the most challenging environments.
