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.
🔧 What Are Copper / Brass / Bronze Forged Bars?
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.
⚙️ Manufacturing Process Followed at Inox Steel India
1️⃣ Billet Selection
Certified billets of CuNi 90/10 and CuZn brass alloys are sourced from approved producers with controlled chemistry.
2️⃣ Hot Forging
Billets are forged using open-die or closed-die forging, producing dense, defect-free forged bars with uniform grain structure.
3️⃣ Heat Treatment
4️⃣ Rough Machining (Optional)
Forged bars can be supplied in rough-machined or near-net shape to reduce downstream machining time.
5️⃣ Inspection & Testing
Each bar undergoes UT, PMI, mechanical testing, and dimensional inspection before dispatch.
