Brass Stamped Parts | Stamped Brass Components | ASTM B36

Brass Stamped Parts & Stamped Brass Components – ASTM Certified | Trusted by US OEMs, Distributors & Industrial Buyers for 30+ Years

Brass stamped parts are the workhorses of American manufacturing — found in everything from door hardware in Chicago high-rises to electrical terminals in Texas switchgear plants, from lock cylinders in California security products to marine fittings on Gulf Coast yachts. Conex Screws and Fasteners has been the trusted India-based source for Brass Stamped Parts and Stamped Brass Components for US buyers for over 30 years. We manufacture from ASTM B36-certified brass strip, press in-house to ASME tolerances, document to US QC standards, and ship to every major US port — making the entire overseas sourcing experience seamless for American procurement teams.

We understand the US brass market: ASTM alloy designations (C26000, C27200, C28000, C36000), inch-dimension drawings with ASME Y14.5 GD&T, free-cutting grades for high-speed stamping, low-lead/lead-free grades for California Prop 65 compliance, and the total-cost math that makes India the smart sourcing decision against both domestic US and Chinese suppliers.

Why US Buyers Choose Conex for Brass Stampings

ASTM B36 Certified Material: Genuine MTCs confirming ASTM chemistry and mechanical properties — not just labels. Our material is traceable from mill to finished part.
Inch-Dimension & Imperial Drawings Accepted: ASME Y14.5 GD&T, inch tolerances, US hardware standard dimensions — we work in your system, not ours.
India-Origin = Section 301 Tariff Exempt: Indian brass stampings avoid Section 301 tariffs applied to Chinese goods — the same quality at significantly lower total landed cost.
Low-Lead & Lead-Free Grades for Prop 65: C26000 and C27200 (low-lead brass) available with Prop 65 compliance support for California-distributed products.
PPAP / FAI / COC Documentation: For US automotive, defense, and aerospace customers who require formal production approval documentation.
Flexible MOQ and Blanket Orders: US distributors and OEMs appreciate our flexibility — from 1,000-piece trial orders to multi-million-piece annual blanket contracts with scheduled releases.

What Are Brass Stamped Parts?

Brass stamped parts (also called stamped brass components, brass pressed parts, or brass sheet metal components in US trade terminology) are manufactured by pressing or stamping brass strip, coil, or sheet through precision hardened steel tooling. Operations include blanking, piercing, bending, forming, deep drawing, coining, and progressive die sequences. In the US market, brass stampings are specified across virtually every industry — from ANSI-standard lock hardware to NEMA electrical connectors, from plumbing fittings per ASME B16.15 to military specification EMI shields and from jewelry findings to architectural interior hardware. Brass’s combination of corrosion resistance, machinability, conductivity, and aesthetics makes it indispensable in American manufacturing.

Key Engineering Properties for US Applications

Free-Cutting Grade Available (C36000): The US favorite for high-speed stamping operations requiring clean edges and excellent secondary machining — specified in ASTM B121 for free-cutting brass stampings.
Good Electrical Conductivity (28–45% IACS): Brass terminals and connectors carry current reliably in UL-listed electrical assemblies and NEC-compliant wiring devices.
Non-Magnetic: Brass stampings don’t interfere with electronic sensors, magnetic locks, or avionics instruments — critical in US aerospace and defense hardware.
Low-Lead Grades for Prop 65 Compliance: C26000 (Cartridge Brass) and C27200 are low-lead alloys compatible with California Prop 65 requirements for consumer products and potable water hardware.
Excellent Spring Properties (CZ106 / C26000): Cartridge brass in half-hard temper is the US standard for precision contact springs, retention clips, and snap rings.
Plating-Friendly: Brass accepts nickel, chrome, gold, silver, and tin plating to standard US specifications — ASTM B456 chrome, ASTM B689 nickel, IPC-4552 tin.

Cartons are ISPM-15 certified. Documentation: ASTM B36 MTC, dimensional inspection report to ANSI/ASQ Z1.4, COC signed by QC manager, RoHS/Prop 65 declaration, COO (India), packing list, and USD commercial invoice. ISF (10+2) pre-arrival filing data provided to US forwarders.

Why US Buyers Choose Conex Over Domestic or Chinese Brass Stamping Suppliers

ASTM Documentation Integrity: Our MTCs are genuine and mill-traceable. US QC managers trust Conex MTCs because they’ve passed third-party verification without exception over 30 years.
India-Origin Section 301 Exemption: Brass stampings from India save 7.5–25% in tariff costs compared to equivalent Chinese-origin parts under current Section 301 tariff schedules.
In-House Tooling Advantage: No third-party toolmaker markup, faster prototyping, and your proprietary die stays in our tool room — not shared with competitors.
Full Customization at Indian Cost Levels: Complex multi-operation stampings, unusual alloys, special tempers, custom platings — viable at Conex cost levels where the same work would be uneconomical at US domestic rates.
IP Protection: We execute NDAs and maintain strict drawing confidentiality. No sharing, no reverse engineering for third parties.
Responsive US-Aligned Communication: Our export team overlaps US business hours, responds to RFQs within 24 hours, and provides USD pricing with full documentation — no back-and-forth delays.

What Separates Conex from Other Overseas Brass Stamping Manufacturers

The overseas brass stamping market is crowded, but very few suppliers combine the following: genuine ASTM documentation, in-house tooling, full temper range, Prop 65-compatible alloy options, PPAP/FAI capability, and a 30-year US customer base that speaks to their reliability. Conex has all of these. Our references from current US customers — OEM manufacturers, distributors, architects, and defense contractors — are our best selling point, and we’re happy to connect prospective US buyers with existing US customers who can speak to their experience. That kind of transparency and confidence is rare among overseas manufacturers, and it’s at the core of how Conex has sustained three decades of US business.

Frequently Asked Questions – US Buyers

Q1. Do your brass stampings meet ASTM B36 specifications?

Yes. We source from ASTM B36-certified mills for all standard brass alloys (C26000, C27200, C28000) and ASTM B121 for C36000 free-cutting brass. Genuine MTCs provided with every order.

Q2. Can you supply low-lead brass for California Prop 65 compliant products?

Yes. Lock cam plates, cylinder spacers, retaining rings, and other brass lock components to ANSI/BHMA A156 series dimensions are a regular product line.

Q4. Are Indian brass stampings subject to Section 301 tariffs?

No. Section 301 tariffs apply primarily to Chinese-origin goods. Indian brass stampings import at standard MFN duty rates under HTS Chapter 74. COO documentation (India) is provided for CBP entry.

Q5. Can you produce brass stampings to ASME Y14.5 GD&T drawings?

Yes. Our tool room and QC team work with ASME Y14.5 GD&T callouts on customer drawings — we read and produce to US geometric dimensioning standards natively.

Q6. Do you supply brass jewelry findings in bulk for US wholesale buyers?

Yes. We supply stamped brass jewelry findings — hooks, clasps, earring findings, ring blanks, charm blanks — in bulk quantities for US wholesale jewelry manufacturers and craft supply distributors.

Q7. What is your process for a new custom brass stamping inquiry?

Send your drawing (PDF, DXF, DWG, or STEP/IGES), ASTM grade, temper, finish/plating, and annual quantity estimate. We respond with USD pricing and tooling cost within 24 business hours.

Q8. Do you supply PPAP documentation for US automotive customers?

Yes. PPAP Level 1 (PSW) through Level 3 (full dimensional, MTC, process capability) is available for automotive OEM and Tier 1 supply chain requirements.

Q9. Can you reverse-engineer brass stampings from a broken sample for US MRO buyers?

Yes. Send us your sample — we measure, create a drawing, develop tooling, and supply matching replacement parts. Popular service for US maintenance, repair, and operations (MRO) buyers.

Q10. What is the total lead time from PO to delivery at a US warehouse?

New tooled part: 4–5 weeks tool development + 1–2 weeks production + 4–5 weeks sea freight = approximately 10–12 weeks total. Repeat orders from maintained tooling: 2 weeks production + freight. Air freight available to shorten transit.

Q11. Do you supply naval brass (C46400) for US marine hardware buyers?

Yes. ASTM B171 C46400 Naval Brass stampings for ABYC-referenced marine hardware, deck fittings, and offshore applications are available. Please specify application for alloy confirmation.
