Grades: CuNi 90/10, CuZn (Brass), CuSn (Bronze) | Supplier & Exporter
Inox Steel India is a trusted manufacturer, supplier, and exporter of copper, brass, and bronze flat bars in India, offering premium-quality CuNi 90/10 (Copper-Nickel), CuZn (Brass), and CuSn (Bronze) flat bars for marine, electrical, engineering, and industrial applications.
Our non-ferrous flat bars are manufactured using controlled hot rolling and extrusion processes, followed by suitable annealing to achieve excellent dimensional accuracy, surface finish, and consistent mechanical properties. These materials are selected where corrosion resistance, electrical/thermal conductivity, wear resistance, and non-magnetic behavior are critical.
Buyers searching for copper flat bars, brass flat bars, bronze flat bars, or CuNi 90/10 flat bar suppliers in India rely on Inox Steel India for certified material, application-based guidance, and reliable domestic & export supply.
Copper, brass, and bronze flat bars are solid rectangular bars made from copper-based alloys, each engineered for specific performance characteristics:
Compared to steel flat bars, non-ferrous flat bars offer better corrosion resistance, conductivity, and performance in specialized environments, especially where steel is prone to rust, galling, or electrical losses.
These properties make copper-based flat bars essential for high-reliability and precision applications.
In India, copper, brass, and bronze flat bars see strong demand in Mumbai, Navi Mumbai, Pune, Ahmedabad, Chennai, and Coimbatore, driven by marine engineering, electrical manufacturing, power equipment, and industrial machinery sectors.
Internationally, CuNi 90/10 flat bars are widely exported to GCC countries, Europe, and Africa for marine and offshore projects, while brass and bronze flat bars are supplied to global engineering and electrical equipment manufacturers.
With dispatch from JNPT (Mumbai), Mundra, and Hazira ports, Inox Steel India ensures export-grade packaging, full traceability, and timely delivery.
