Copper Stamping, Copper Stamped and Pressed Parts from Jamnagar
Copper stamped parts and copper pressed parts are components manufactured by pressing or stamping sheet copper or copper strip through precision tooling and dies. These parts are critical in electrical, electronic, automotive, and thermal management applications where high conductivity, excellent ductility, and corrosion resistance are essential. Jamnagar Brass Components operates progressive stamping and deep drawing presses to manufacture copper stampings to tight tolerances and complex geometries, serving OEMs and distributors in the USA, Canada, and Europe.

Frequently Asked Questions (FAQ)
Q: What copper strip thicknesses can you stamp?
A: We can stamp copper strip from 0.2mm (0.008″) to 6mm (0.236″) thickness depending on the part geometry and press capacity.
Q: Can you supply copper stampings with silver plating for electrical contacts?
A: Yes. We offer silver plating (5–25 microns) on copper contacts and bus bar sections. Silver plating greatly reduces contact resistance and prevents tarnishing in relay and contactor applications.
Q: Do you offer design assistance for copper stamping tooling?
A: Our in-house tool engineers can review your designs for manufacturability (DFM), suggest material gauge optimizations, and design progressive dies that minimize scrap and maximize production rate.
Q: What is the lead time for copper stamped parts?
A: For new tooling + first production run: 6–10 weeks. For repeat orders on existing tooling: 3–5 weeks. Express tooling programs available for faster time-to-market.
