Leveraging over two decades of die design expertise and high-tonnage press capabilities, we deliver dimensionally accurate, burr-free brass stampings to US OEMs, distributors, and Tier-1 suppliers.

Understanding Brass Stamping

Brass stamping is a manufacturing process where brass sheet or strip (coil stock) is fed into precision tooling housed in a mechanical or hydraulic press. The die set performs a series of operations — blanking, piercing, bending, forming, coining, or embossing — to produce finished components. Progressive die stamping enables hundreds of stampings per minute, making it ideal for high-volume brass parts like terminals, connectors, brackets, and clips.

Understanding Brass Pressing (Deep Drawing)

Brass pressing refers to deep drawing and press forming of brass blanks into cups, shells, caps, and hollow components. The excellent ductility of brass alloys like C26000 (cartridge brass, 70/30) makes it the material of choice for deep-drawn parts such as shell casings, plumbing bodies, musical instrument components, and decorative hardware.

Frequently Asked Questions — Brass Stamping & Pressing

Q1: What brass alloys are available for stamping and pressing?

We press all major brass alloys including CZ106 (C26000, cartridge brass 70/30, best for deep drawing), CZ108 (C28000, 60/40 common brass, most economical), CZ107 (C27000, 65/35 yellow brass), CZ120 (C35000, semi-leaded), and CZ121 (C36000, free-machining). Alloy selection depends on draw depth, corrosion requirements, and whether plating is required.

Q2: What is the deepest draw ratio achievable in brass?

Cartridge brass (CZ106, C26000) achieves draw ratios of up to 2.2:1 in a single stage with correct lubrication and die geometry. Multi-stage redraw operations can achieve total draw ratios of up to 4:1 or more for deep cylindrical shells. Intermediate annealing between stages restores ductility to allow further drawing without cracking.

Q3: What tolerances can you achieve on brass pressed parts?

Blanked profiles: ±0.05 mm. Formed and bent dimensions: ±0.1 mm. Deep-drawn shell height and diameter: ±0.15 mm. Fine-blanked parts with perpendicular edges: ±0.02 mm. Coined surfaces (flat faces): thickness tolerance ±0.01 mm. These are production tolerances for runs above 5,000 pieces; prototype tolerances are confirmed case by case.

Q4: Do you offer stress relief annealing for brass deep-drawn parts?

Yes. Deep-drawn brass parts carry residual tensile stress from the drawing process, making them susceptible to stress corrosion cracking (SCC) in ammonia-containing environments. We offer low-temperature stress relief annealing at 200 to 250 degrees Celsius for 1 hour as standard for deep-drawn components destined for humid, industrial, or chemical environments, at minimal additional cost.

Q5: What plating options are available on brass stampings?

Available plating options include: bright nickel (3–10 µm), electrolytic tin (5–15 µm bright or matte), silver (3–15 µm), chrome (decorative and hard chrome), gold (0.1–3 µm for connectors), and antique brass or copper-bronze patina finishes for decorative hardware. All plating is applied by approved plating partners with quality certification.

Q6: Can you manufacture brass progressive die parts for automotive applications?

Yes. We supply brass stampings for automotive electrical systems, instrument clusters, and HVAC controls. For automotive customers, we offer PPAP (Production Part Approval Process) documentation, FMEA, control plans, and Cpk capability studies on critical dimensions. IATF 16949 aligned quality procedures are available for Tier 1 and Tier 2 automotive supplier requirements.

Q7: What is the typical tooling cost for brass stamping dies?

Tooling costs range from USD 400 to 800 for simple compound blanking dies, USD 1,500 to 4,000 for 3 to 5 station progressive dies, and USD 5,000 to 12,000 for complex 8 to 12 station progressive dies with forming, coining, and assembly features. Deep-draw tools for shells and cups: USD 2,000 to 8,000 depending on diameter, depth, and number of redraw stages.

Q8: What is your production capacity for brass stampings?

Our press shop operates 18 presses from 25 to 400 tonnes running two shifts, capable of producing 500,000 to 5,000,000 small stampings per month depending on part complexity and cycle time. For simple blanked parts on high-speed presses, output can exceed 50,000 hits per hour per press. We can accommodate urgent capacity requirements with additional shift allocation.

Q9: Can you supply brass stampings in coil or strip form?

Yes. Carrier-strip stampings (parts attached to the strip for automatic assembly or selective plating) are a standard delivery format for high-volume connector contacts, terminals, and lead frames. We supply on reel or fold-packed in magazine strips per customer specification. Strip width, carrier pitch, pilot holes, and registration features are designed to match customer automatic assembly equipment.

Q10: How do I get a quote for a brass stamping project?

Email your 2D drawings (PDF or DXF) or 3D CAD files to sales@jambrass.com with: material specification, required tolerances, annual volume, surface finish, and any plating or special packaging requirements. For progressive die projects, include the full strip layout if available. We respond with tooling cost, unit price, and lead time within 24 to 48 business hours.
