Stamped Battery Contact Clips: Materials and Plating Options
Stamped battery contact clips connect cell terminals in battery holders and packs. They are punched and formed from strip material, which makes them consistent and economical at volume.
The material and plating decide conductivity, spring force, and corrosion resistance.
Phosphor bronze for conductivity
Phosphor bronze combines good conductivity with corrosion resistance and spring properties. It is a common choice for battery contacts that must carry current reliably over many insertions.
It costs more than steel but removes the need for a conductive plating layer in many designs.
Plated spring steel for force and cost
Spring steel provides higher force and lower material cost. Nickel plating is then added for conductivity and corrosion resistance. The result is a strong, economical contact.
This combination is common when the contact must hold a heavier cell or withstand vibration.
Plating options
| Plating | Benefit | Typical use |
|---|---|---|
| Nickel | Conductivity, corrosion resistance, solderability | General battery contacts |
| Tin | Solderability, conductivity | Soldered connections |
| Gold (selective) | Low contact resistance | Signal or low-current contacts |
Plating choice depends on the connection method and current. Nickel is the workhorse for battery contacts.
What to specify
- Cell format (18650, AA, size C, etc.).
- Contact type and mounting method.
- Material and plating.
- Required contact force.
- Connection method (solder, rivet, or press-fit).
A sample holder or drawing removes ambiguity about orientation and mounting.
FAQ
Phosphor bronze or plated steel—which is better?
Phosphor bronze for conductivity and corrosion resistance; plated spring steel for higher force at lower cost. Confirm the recommendation for your application.
Can you make clips for 18650 battery packs?
Yes. Stamped contacts for 18650 and other cylindrical cells are available. Provide the cell layout and connection requirements.
What plating is standard for battery contacts?
Nickel plating is common for its conductivity, corrosion resistance, and solderability.
Do stamped contacts need a sample before production?
A sample is recommended to verify fit and contact force in your holder before committing to a production run.
Can the clip be soldered or riveted?
Yes. Specify the connection method and the supplier can design the contact accordingly.
What contact force do I need?
It depends on the battery weight and vibration. Share the application and the supplier can recommend a force range for a stable connection.
Match material and plating to the application
Stamped battery contacts are reliable when material, plating, and force are specified together. Send the cell format, connection method, and a drawing or sample to get an accurate quote.
