Brass & Copper Parts India is a leading manufacturer and global exporter of precision copper stamped parts and copper stamping components, serving customers across the United States, Canada, Germany, the UK, and more. With over two decades of manufacturing expertise, we deliver high-volume, tight-tolerance copper stampings that meet the most demanding industrial and commercial specifications.
What Is Copper Stamping?
Copper stamping is a cold-forming metalworking process in which flat copper sheets or coils are fed into a stamping press equipped with precision dies to produce complex shapes, geometries, and profiles. The process encompasses a range of operations — including blanking, piercing, bending, coining, forming, and deep drawing — all of which can be performed in a single progressive die tool or in multi-stage tooling setups. Copper’s high ductility, outstanding electrical conductivity (approximately 100% IACS), and excellent corrosion resistance make it an ideal material for stamping applications across electrical, electronics, automotive, telecommunications, and plumbing industries.
At Brass & Copper Parts India, our state-of-the-art stamping presses range from 25 tons to 400 tons, enabling us to produce copper stampings in thicknesses from 0.1 mm to 6 mm and in widths up to 400 mm with consistent dimensional accuracy across millions of parts. Our progressive tooling technology enables simultaneous multi-operation forming in a single pass, dramatically reducing per-piece cost for high-volume orders.
Copper Stamped Parts – Types and Product Range
Our copper stamped parts portfolio covers a comprehensive range of profiles and geometries to serve diverse application needs. Each part is manufactured using precision-ground tooling and inspected against first-article and in-process quality checkpoints.
Copper Stamped Electrical Contacts and Terminals
Electrical contacts and connector terminals are among the most critical copper stampings we produce. These components require exceptional dimensional consistency, smooth surface finish, and reliable electrical conductivity across their entire service life. We manufacture spring-loaded contacts, relay contacts, socket terminals, pin contacts, blade connectors, press-fit terminals, and ring terminals in C11000, C10100, and C10200 copper grades. Our stamped electrical contacts are used in switches, relays, connectors, busbars, and control panels across the automotive, industrial, and consumer electronics sectors in the United States and globally.
Copper Stamped Busbars and Bus Connectors
Busbars formed by copper stamping offer superior current-carrying capacity, compact form factor, and precise drilling or punching of mounting holes in a single tooling pass. We manufacture laminated and solid copper busbars for switchgear, motor control centers (MCCs), power distribution boards, battery management systems (BMS), and EV charging infrastructure. Stamped copper busbars from our facility are exported to major US electrical equipment manufacturers and OEM panel builders, meeting UL and NEMA standards.
Copper Stamped Terminals, Lugs, and Connectors
Copper cable lugs, compression terminals, and crimp connectors produced through the stamping process provide excellent mechanical strength and electrical reliability. Our stamped copper lugs are available in DIN, UL, and CSA-compliant profiles, with tin-plating, silver-plating, or bare copper finish as required. These are widely used in US electrical distribution panels, industrial motor wiring, grounding systems, and renewable energy applications including solar and wind installations.
Copper Stamped Grounding Strips and Earth Plates
Ground plates and earth strips require precise punching, profiling, and surface treatment for long-term reliability in electrical grounding systems. We manufacture copper grounding strips, earth bars, and lightning protection plates via progressive stamping and blanking tools, ensuring accurate hole patterns and flat, burr-free edges. These are supplied to electrical contractors, utilities, and industrial facility managers in the USA and Canada.
Copper Stamped Shims, Washers, and Spacers
Precision copper shims, washers, and spacers produced by stamping are widely used in heat sink assemblies, transformer cores, motor assemblies, and precision instruments. We can produce stamped copper shims as thin as 0.05 mm with bore tolerances held to ±0.01 mm. Standard and custom OD/ID configurations are available, including square, rectangular, and irregular profiles per customer drawings or DXF/CAD files.
Copper Stamped Heat Sink Clips and Spring Parts
Copper’s high thermal conductivity (approximately 385 W/m·K) makes it the material of choice for heat management components. We produce stamped copper heat sink clips, spring contacts, thermal interface clips, and heat spreader plates for the semiconductor, power electronics, and LED lighting industries. These components are manufactured with controlled spring-back compensation built into our tooling design, ensuring consistent force and geometry across production runs.
Copper Stamped Automotive Parts
The automotive industry relies on copper stampings for a wide range of electrical and electronic systems. We produce copper terminal stampings for automotive wiring harnesses, stamped copper ring terminals for battery cables, copper contact pads for EV charging couplers, and copper bus plates for battery management modules. Our automotive-grade stampings are manufactured in compliance with IATF 16949-aligned quality systems, with full PPAP documentation available upon request for US Tier-1 and Tier-2 automotive suppliers.

Frequently Asked Questions (FAQ) – Copper Stamping
Q1. What is the minimum order quantity (MOQ) for copper stamped parts?
Our standard MOQ for copper stamped parts is 5,000 pieces for prototype or initial production orders. For established high-volume programs, we offer blanket purchase order (BPO) arrangements with scheduled releases as low as 1,000 pieces per shipment. Contact our sales team to discuss your specific volume requirements and we will recommend the most cost-effective supply arrangement.
Q2. What thickness range of copper sheet can you stamp?
We routinely stamp copper sheets and coils from 0.1 mm to 6.0 mm thickness. For ultra-thin stampings below 0.1 mm, please consult our engineering team as specialized fine-blanking or photochemical etching techniques may be more appropriate depending on the geometry and tolerances required.
Q3. Can you stamp hardened or tempered copper?
Yes. We work with copper in a range of temper conditions including dead soft (O60), half-hard (H01), hard (H02), spring temper (H04), and extra spring (H06). The appropriate temper is selected based on the springback requirements, formability needs, and end-use mechanical performance of each part.
Q4. What tolerances can you achieve in copper stamping?
Standard stamping tolerances for copper parts are ±0.05 mm for blanked profiles and ±0.1 mm for formed dimensions. For tight-tolerance applications, we achieve ±0.01 mm on blanked features using precision fine-blanking tooling and CMM-verified first-article qualification. Please provide your drawing with GD&T callouts for a detailed tolerance feasibility review.
Q5. Do you offer plated copper stampings ready for assembly?
Yes. We offer complete value-added services including electroplating (tin, nickel, silver, gold), annealing, deburring, and part marking. We supply plated copper stampings in bulk bags, tape-and-reel (for SMT applications), or custom packaging per customer requirements — ready for direct use in your assembly or sub-assembly process.
Q6. Can you manufacture copper stampings to customer-supplied DXF or CAD drawings?
Absolutely. We accept 2D DXF, DWG, PDF drawings and 3D STEP, IGES, SolidWorks, and Pro-E/CREO files. Our engineering team performs a DFM (Design for Manufacturability) review on all new designs and provides tooling layout proposals, strip layout drawings, and cost estimates within 3–5 business days of receiving complete drawing packages.
Q7. What is your typical lead time for copper stamping tooling and first parts?
Tooling lead time for standard progressive dies is 4–6 weeks from drawing approval. For simple blanking or compound dies, tooling can be ready in 2–3 weeks. First-article samples are provided within 1–2 weeks of tooling completion. Production lead time for volume orders is typically 3–4 weeks after first-article approval.
Q8. Are your copper stampings RoHS and REACH compliant?
Yes. All copper stampings and their associated surface finishes (tin, nickel, silver plating) are supplied RoHS-compliant (2011/65/EU and 2015/863 amendment) and REACH-compliant (EC 1907/2006). Compliance declarations and material data sheets (MDS) are available upon request and routinely provided with export shipments to European and US customers with environmental compliance requirements.
