What Are Copper Sheet Metal Parts?
Copper sheet metal parts are components manufactured from flat copper sheets or coils through various metal forming processes including stamping, blanking, punching, bending, deep drawing, roll forming, and laser/water jet cutting. Copper’s exceptional electrical conductivity (100% IACS for ETP copper), thermal conductivity, corrosion resistance, and antimicrobial properties make copper sheet components indispensable across electrical, electronics, HVAC, plumbing, and medical industries.

Typical Q&A — Copper Sheet Metal Parts
1. What copper grades are suitable for sheet metal stamping?
ETP copper (C11000/C101) is the most widely used for copper sheet metal stampings due to its balance of conductivity, formability, and cost. OFHC copper (C10200/C103) is used for high-purity electronics applications. Phosphor deoxidized copper (C12200/C106) is preferred for weldable HVAC components.
2. What is the minimum copper sheet thickness you can stamp?
We can stamp copper sheet as thin as 0.3 mm using compound and progressive dies. For copper shims and contact strips, we can work with 0.05 mm copper foil stock using specialized fine-blanking tooling.
3. Can you supply tinned copper sheet metal parts?
Yes. We offer in-house electrolytic tin plating (bright tin and matte tin) and hot-dip tinning for copper sheet parts. Tin plating thicknesses from 2 µm to 25 µm are available per IEC, ASTM B545, and customer specifications.
4. What standards do your copper sheet metal parts comply with?
Our copper sheet parts are manufactured from material complying with ASTM B152 (USA), BS EN 13601 (Europe), DIN EN 1652, JIS H 3100 (Japan), and IS 1545 (India). RoHS 2 and REACH SVHC compliance declarations available.
5. Can you deep-draw copper into cups and shells?
Yes. Our deep drawing capability for copper encompasses cups, shells, caps, and enclosures up to ∅200 mm diameter and depth-to-diameter ratios of 2:1. We use multi-stage tooling with intermediate annealing for complex draws.
6. What tolerances can you achieve on copper stampings?
Standard tolerance for copper stampings is ±0.1 mm on profile dimensions and ±0.05 mm on hole diameters. Fine-blanking processes achieve ±0.02 mm on sheared edges with near-perfect flatness and burr-free edges.
7. Do you offer laser cutting for copper sheet parts?
Yes. We use fibre laser cutting for prototype quantities and complex custom shapes in copper sheet from 0.5 mm to 6 mm thickness. Laser cutting is ideal for short runs, prototypes, and irregular geometries before investing in tooling.
8. What is the typical lead time for copper sheet metal parts?
Tooling (new die): 3–4 weeks from drawing approval. First article samples: 1 week after tooling. Production: 3–4 weeks. Overall first-order lead time: 4–6 weeks. Repeat orders on existing tooling: 3–4 weeks.
9. Can you supply copper bus bar stampings for switchgear?
Yes. We manufacture punched, bent, and formed copper bus bars from 3 mm to 12 mm thickness for LV and MV switchgear panels, distribution boards, and transformer terminations. ETP and HC copper grades available, with tin or silver plating options.
10. What is the difference between copper sheet and copper plate?
Copper sheet is typically defined as copper in thicknesses from 0.25 mm to 6 mm, while copper plate is over 6 mm thick. Both can be used for sheet metal parts, though plate is usually machined rather than stamped. We work with both categories.
11. Do you supply copper EMI/RF shielding parts?
Yes. We manufacture copper RF shielding enclosures, EMI gaskets, Faraday cage components, and shielding cans from OFHC and ETP copper sheet for electronics and defence applications.
12. Can you provide copper heat sink blanks and fin stock?
Yes. We supply corrugated copper fin stock, punched copper fin arrays, and copper heat sink base plates for power electronics and thermal management applications.
13. What is VCI packaging for copper parts?
VCI (Volatile Corrosion Inhibitor) packaging uses a film impregnated with corrosion inhibitors that volatilise and form a protective molecular layer on copper surfaces, preventing tarnishing and oxidation during long-distance shipping and storage.
14. Do you offer silver-plated copper sheet parts?
Yes. Silver plating (0.5 µm – 25 µm) is available for copper contact blanks and electrical connectors where low contact resistance and high-temperature performance are required. We offer both rack and barrel silver plating.
15. What certifications do you hold for copper sheet metal manufacturing?
Brass Parts India is ISO 9001:2015 certified. We supply material test certificates (MTC), certificate of conformance (CoC), RoHS/REACH declarations, and inspection reports with every shipment of copper sheet metal parts.
16. Can you supply copper sheet parts for the EV (Electric Vehicle) industry?
Yes. We supply copper bus bar stampings, copper terminal blanks, battery connector components, and copper flexible laminates for EV battery modules and power distribution units — manufactured to automotive-grade quality standards.
