Spring Materials for Custom Precision Springs
Choose spring materials around load, torque, corrosion, conductivity, surface finish and inspection needs. Final material selection should be confirmed from the drawing and application.
Common Spring Materials for RFQ Review
| Carbon steel | Often reviewed for general spring performance where corrosion exposure and finish requirements are manageable. |
|---|---|
| Stainless steel | Reviewed when corrosion resistance, appearance or cleaner environments are important. |
| Music wire | Commonly reviewed for many precision spring applications where spring performance is the priority. |
| Phosphor bronze | Often considered for conductive contacts, battery springs and corrosion-sensitive electrical applications. |
| Brass | Reviewed for conductive, formed or appearance-related components depending on design requirements. |
| Project-specific material | Material can be reviewed against load, torque, environment, conductivity, finish and cost targets. |

Frequently Asked Questions
Which material should I choose for a custom spring?
Material depends on load, torque, environment, conductivity, finish and cost targets. Include application notes with the RFQ for review.
Can conductive spring materials be reviewed?
Yes. Phosphor bronze, brass and other conductive material needs can be reviewed for battery contact springs and touch springs.
Should finish be specified in the drawing?
Yes. Surface finish, plating, passivation or appearance requirements should be included in the drawing or RFQ notes.
