Grades: CuNi 90/10, CuZn (Brass)
Inox Steel India is a reliable manufacturer, supplier, and exporter of Copper, Brass, and Bronze Forged Bars, offering precision-forged solutions in CuNi 90/10 (Copper–Nickel) and CuZn (Brass) grades for industrial applications across India, GCC, Middle East, Africa, Europe, and North & South America.
Copper-based forged bars are widely preferred for applications where excellent corrosion resistance, high thermal and electrical conductivity, and superior machinability are critical. Through controlled forging processes, these materials achieve improved grain structure, higher mechanical integrity, and longer service life compared to cast or rolled copper alloys.
At Inox Steel India, copper and brass forged bars are manufactured using hot forging followed by annealing or stress relieving, ensuring compliance with ASTM standards and consistent performance in marine, heat transfer, and engineering systems.
Copper / brass / bronze forged bars are solid metal sections produced by hot forging copper-based alloy billets under compressive force, which enhances internal grain flow and eliminates shrinkage defects commonly found in cast products.
Compared to cast or extruded bars, forged copper alloys offer:
These advantages make forged copper alloys ideal for marine components, heat exchangers, valves, fittings, and precision-engineered parts.
🔹 CuNi 90/10 Forged Bars
CuNi 90/10 is a copper–nickel alloy with outstanding resistance to seawater, marine atmospheres, and biofouling. It is widely used in marine hardware, heat exchangers, condensers, offshore piping components, and desalination systems.
🔹 CuZn (Brass) Forged Bars
CuZn brass alloys offer excellent machinability, good corrosion resistance, and high electrical conductivity, making them ideal for valves, fittings, fasteners, electrical components, and general engineering applications.
