From the heart of Kinshasa, Congo, Okoye Nickel Alloys stands as a trusted partner for industries demanding uncompromising quality in corrosive environments. We specialize in the precision manufacturing and supply of robust Copper Nickel 7030 forged fittings. Our dedication lies in providing components that are built to last, offering exceptional resistance to saltwater corrosion for the demanding maritime and offshore sectors that are so vital to regional and global economies. With a firm commitment to reliability, we ensure your projects are supported by fittings engineered for performance and longevity.
Copper Nickel 7030, also known as cupronickel 70/30, has a distinct composition of about 70% copper and 30% nickel, with small but crucial additions of iron and manganese. This specific blend gives the material its renowned strength and durability. The resulting forged fittings exhibit impressive mechanical properties, including high tensile strength and excellent ductility, allowing them to withstand significant pressure and mechanical stress. They are particularly valued for their outstanding resistance to erosion and corrosion, especially in challenging seawater applications, making them a fundamentally reliable choice.
