Forging Brass Rods (Hot Forging Grades)
Product Overview
Forging Brass Rods supplied by R V Metal Corporation are specifically manufactured for hot forging, precision forging, and closed-die forging applications where high strength, excellent hot workability, and dimensional consistency are critical. Produced from carefully controlled copper-zinc alloys with optional lead, aluminium, manganese, or silicon additions, these rods offer superior resistance to cracking, excellent metal flow under forging temperatures, and consistent grain structure after deformation. Our forging brass rods are widely used in the production of valves, plumbing components, electrical fittings, automotive parts, fasteners, and heavy-duty industrial hardware, where reliability under thermal and mechanical stress is non-negotiable.
Available in round, hexagonal, square, and custom profiles, R V Metal Corporation’s forging brass rods are supplied in hot-extruded or hot-rolled condition with tight chemical and dimensional tolerances to meet ASTM, EN, IS, and OEM-specific forging standards. These rods are engineered to minimize die wear, reduce forging defects, and improve tool life, making them the preferred choice for high-volume forging operations, CNC-assisted forging lines, and export-oriented manufacturers demanding repeatable performance and traceability.

| Notes (EPC / Consultant Grade) | |||
|---|---|---|---|
| 1) Weight Basis | Weights shown are theoretical and may vary with alloy chemistry, tolerance, surface condition and straightness. | ||
| 2) Density Assumption | Density assumed at 8.40 g/cm³ (typical forging brass range ~8.35–8.55 g/cm³). For contract-critical projects, weight should be recalculated per heat/grade. | ||
| 3) Supply Conditions | Available in extruded and cold-drawn conditions; straightness and machining allowance should be defined in PO for CNC/forging dies. | ||
| 4) Cut Length Tolerance | Standard commercial cut tolerance applies unless specified; for automatic forging lines, specify tight cut length tolerance and end squareness. | ||
