What Is a Beryllium Copper Spring for Relays?
Beryllium Spring for Relay is a precision-stamped electrical spring component manufactured from beryllium copper alloy, with C17200 specified for applications requiring a combination of electrical conductivity, elastic strength and resistance to repeated mechanical loading. Its copper-based alloy structure supports current conduction while its precipitation-hardened condition provides the spring force required for relay contact mechanisms.
Designed for relay moving contacts, contact pressure systems and internal conductive spring assemblies, the component can be manufactured according to customer drawings, including specified thickness, spring geometry, bending angles, mounting features and surface treatment. Custom stamping production supports prototype evaluation, engineering validation and repeat wholesale orders for relay manufacturers.

01
Automotive Relay Assemblies
Automotive relay applications include lighting control relays, wiper relays, horn relays and auxiliary power control modules.
02
Smart Home and Control Relay Modules
Smart home control systems use compact relays in lighting control modules, smart switches, HVAC control boards and household appliance control circuits.
03
Industrial Control and Power Relay Systems
Industrial power relays and control relays require spring components compatible with their rated current, switching frequency and mechanical contact arrangement.
04
Storage Recommendation of High-Conductivity Copper Stamping
To protect beryllium copper relay springs from oxidation and mechanical deformation before assembly:
- Store within dry, humidity‑controlled environment
- Avoid direct sunlight and dramatic temperature variation
- Do not apply heavy mechanical compression to springs during storage
- Use anti‑static and moisture‑proof packaging for stock‑keeping
