What Is Copper Stamping?
Copper stamping is a cold-forming metalworking process in which copper sheet or strip is placed in a stamping press and shaped by a die set into the desired geometry. Operations include blanking (cutting the outer profile), piercing (cutting holes), bending, embossing, coining, drawing, and notching. Progressive die stamping performs multiple operations simultaneously, enabling high-speed, cost-effective production of complex copper stamped parts from strip or coil. Compound die stamping performs blanking and piercing in a single stroke for simpler copper stampings.

Customer Testimonials
“We’ve been sourcing ETP copper terminal stampings and contact blanks from Brass Parts India for our electrical panel manufacturing for four years. Their progressive die work is excellent — tolerances are consistent, tin plating is uniform, and delivery is always on schedule. They also helped us redesign one component for better stampability, saving us significant tooling cost.”
— Robert Mackenzie, Manufacturing Director, Canada
“Brass Parts India supplied us 50,000 copper grounding pad stampings per month for our solar mounting systems. Quality is excellent — every batch passes our incoming inspection. Their communication is refreshingly straightforward for an offshore supplier, and they proactively flag any potential issues before shipment.”
— Harriet Norwood, Global Procurement Lead, United Kingdom
Typical Q&A — Copper Stamped Parts and Copper Stamping
1. What is the difference between blanking and piercing in copper stamping?
Blanking cuts the outer profile of a copper stamped part from the sheet — the blank is the part, and the surrounding sheet is scrap. Piercing cuts holes in the copper stamped part — the punched-out slug is scrap. In progressive die stamping, both operations are performed in sequence along the copper strip.
2. What copper alloy is best for electrical contact stampings?
ETP copper (C11000) is best for general electrical contact stampings where maximum conductivity (100% IACS) is required. Phosphor bronze (C51000) is used where spring properties and wear resistance are needed. Beryllium copper (C17200) is chosen for the highest-performance spring contacts requiring both high conductivity and very high strength after age hardening.
3. What is progressive die copper stamping?
Progressive die copper stamping uses a die set with multiple stations — each station performs one operation (blank, pierce, bend, emboss, coin, draw) on the copper strip as it advances through the die. In a single press stroke, all stations work simultaneously, so a finished copper stamped part exits the die with every stroke. This makes it ideal for high-volume, complex copper stampings.
4. What tolerances can you achieve in copper stamping?
Standard copper stamping tolerances: profile ±0.1 mm, holes ±0.05 mm. Precision stamping: profile ±0.05 mm, holes ±0.03 mm. Fine blanking: ±0.02 mm on edges and holes with burr-free shear faces.
5. Can you supply copper stampings on a reel/tape for automated assembly?
Yes. We supply copper connector and contact stampings on continuous carrier strip or on reel, compatible with automated placement and insertion machines (per EIA-481 / IEC 60286 carrier tape standards where applicable).
6. What is the minimum sheet thickness for copper stamping?
We can stamp copper as thin as 0.05 mm (copper foil) using fine-blanking techniques for precision shims and contact foils. Standard copper stamping starts from 0.3 mm sheet using compound or progressive dies.
7. Do you provide PPAP documentation for copper stamped parts?
Yes. For automotive customers, we prepare Production Part Approval Process (PPAP) documentation including dimensional inspection report, material test certificate, process capability study (Cpk), and control plan — to AIAG PPAP Level 3 standard on request.
8. What is the lead time for copper stamping tooling?
Tooling lead time: 3–4 weeks for new progressive or compound dies (simple to medium complexity). Complex multi-stage progressive dies: 4–6 weeks. First article samples are delivered 1 week after tooling completion.
9. What surface finishes are available for copper stampings?
Available surface finishes include: bare bright copper, matte tin plating (1–15 µm), bright tin plating, silver plating (2–50 µm), nickel plating (5–25 µm), gold plating (flash, 0.1–2 µm), and passivation. All plating is performed in our in-house facility.
10. Can you deep draw copper into cups and shells?
Yes. We perform multi-stage deep drawing of copper (ETP, DHP, cartridge brass CZ106) for cups, caps, shells, and housings up to ∅180 mm diameter with depth-to-diameter ratios of up to 2:1, with intermediate annealing between drawing stages.
11. Are your copper stampings RoHS and REACH compliant?
Yes. All copper alloys we use are RoHS 2 and REACH SVHC compliant. We provide compliance declarations with every shipment. Tin plating is lead-free per IEC 62368-1 and ASTM B545.
12. What is fine blanking and when is it used for copper?
Fine blanking is a precision stamping process producing burr-free, square-shear-edge copper stampings with flatness tolerances to ±0.02 mm. It is used for copper bus bar blanks, contact blanks, and precision disc stampings where smooth edges and tight tolerances are critical.
13. Can you stamp copper in high volumes?
Yes. Our high-speed progressive die presses run at up to 400 SPM, enabling production of hundreds of millions of copper stampings per year from our facility. We have supplied copper contact stampings in excess of 5 million pieces per month to a single customer.
14. What is the difference between copper stamping and copper forging?
Copper stamping is a cold-forming process from flat sheet/strip producing relatively thin parts (typically <12 mm). Copper forging uses heated copper billets pressed in closed dies to produce thick, 3D parts with higher strength from work hardening and grain refinement. We offer both copper stampings and copper forged parts depending on your application requirements.
15. Do you supply copper bus bar stampings for EV battery systems?
Yes. We supply ETP and OFHC copper bus bar stampings, punched copper inter-cell connectors, and copper battery terminal stampings for EV battery module assembly. We supply to both Tier 1 automotive suppliers and EV OEMs globally.
16. What documentation is included with copper stamped parts shipments?
Every shipment includes: packing list, certificate of conformance (CoC), material test certificate (MTC), RoHS/REACH compliance declaration, plating certificate (where applicable), first article inspection report (for new parts), and MSDS/SDS sheets.
