What Are Brass Forging Parts?
Brass forging parts (also known as hot forged brass components, brass drop forgings, or brass die forgings) are manufactured by heating brass billets to a plastic state (typically 650–750°C) and pressing or hammering them into a precision die cavity under high pressure. The forging process produces a grain-refined, porosity-free microstructure with superior mechanical properties — higher tensile strength, better ductility, and improved pressure-tightness compared to machined or cast brass parts. Jamnagar Brass Components operates multiple closed-die hot forging presses to manufacture a comprehensive range of brass forgings for the US plumbing, HVAC, valve, and industrial markets.
Types of Brass Forging Parts We Manufacture
Brass Forged Valve Bodies and Valve Bonnets
Hot-forged brass valve bodies for ball valves, gate valves, globe valves, and check valves. Forged valve bodies are pressure-tight and structurally superior to cast valve bodies, meeting ASME B16.34 and MSS SP-110 requirements for the US valve market. Available in 1/4″ through 4″ NPS sizes.
Brass Forged Compression Fittings
Forged brass compression fittings including couplings, elbows, tees, and unions. The forging process ensures void-free metal for leak-free performance in potable water and gas service, compliant with ASTM B283 and ASSE 1061 standards required by US plumbing codes.
Brass Forged Flanges
Hot-forged brass flanges in slip-on, weld-neck, threaded, and blind configurations. Manufactured to ASME B16.5 Class 150 and Class 300 dimensions for US industrial piping systems. Widely used in chemical processing, water treatment, and HVAC applications.
Brass Forged Hose Ends and Swage Fittings
Forged brass hose ends, swage ferrules, and hose nipples for hydraulic hose assemblies. Forging ensures the high radial strength required for hydraulic hose crimping without cracking — critical for SAE 100R series hydraulic hose standards.
Brass Forged Pipe Fittings (NPT)
Forged brass pipe nipples, elbows, tees, crosses, and couplings in NPT (National Pipe Taper) thread form. Manufactured to ASME B16.3 and MSS SP-83 standards, pressure-rated for 125–300 PSI service in the US plumbing market.
Brass Forged Automotive and HVAC Components
Forged brass manifolds, adapters, refrigerant fittings, and port connectors for HVAC and automotive cooling systems. Forging ensures the dimensional stability and pressure integrity required for R410A, R134a, and R22 refrigerant systems.
Brass Forged Electrical Components
Forged brass grounding clamps, split bolts, lug bodies, and connector housings for the US electrical industry. Hot forging produces the high mechanical strength and conductivity needed for NEC-compliant grounding and bonding connections.
Custom Brass Forgings to Drawing
We manufacture custom brass forgings from customer drawings, 3D models, or samples. Our in-house die shop designs and manufactures closed-die tooling for net-shape and near-net-shape brass forgings in quantities from 1,000 to 5 million pieces per year.

Frequently Asked Questions (FAQ)
Q: What is the ASTM standard for brass forgings used in US plumbing valves?
A: ASTM B283 covers copper and copper-alloy die forgings for plumbing and industrial applications. UNS C37700 (Forging Brass) is the primary alloy specified. Our forgings fully comply with ASTM B283 chemical composition and mechanical property requirements.
Q: Can you supply NSF-61 certified brass forgings for potable water applications?
A: Yes. We supply DZR brass (UNS C69300) and silicon brass (UNS C87300) forgings that comply with NSF/ANSI 61 and California AB 1953 lead content limits for potable water contact. Third-party NSF testing reports are available.
Q: What is the typical lead time for new brass forging tooling and first production?
A: Die design and manufacture typically takes 4–6 weeks. First production trial and approval takes an additional 2–3 weeks. Total new-tool-to-first-delivery lead time is generally 8–10 weeks.
Q: Do you offer secondary CNC machining after forging?
A: Yes. We provide fully finished forging + machining combinations, delivering parts ready for assembly. Typical secondary operations include bore machining, thread tapping, face milling, and cross-drilling.
Q: What is the minimum quantity for brass forgings?
A: The economic minimum for most brass forgings is 1,000 pieces due to die cost amortization. For very large or complex parts, MOQ may be 500 pieces. We also offer prototype forging programs using existing approximate dies for concept validation before full tooling investment.
