High Conductivity Beryllium Copper Alloys for Armature Springs

High-concrient beryllium copper (BeCu) alloys are an excellent choice for armature springs in various electrical devices due to their superior material characteristics. Armature springs are a type of contact spring used in electromagnetic devices such as relays, solenoids, and certain types of electric motors. These springs play a crucial role in the operation of the armature, the movable component that is actuated by the magnetic field generated by the flow of electric current.

Armature Springs:

Armature springs are essential for the proper functioning of electromagnetic devices. They provide the necessary force to return the armature to its original position after actuation and ensure that the contacts within the device make or break the circuit as intended.

Key Requirements for Armature Springs:

  • Responsive Actuation: They must allow for quick and precise movement of the armature in response to electromagnetic forces.
  • Consistent Force: Springs should provide a consistent force over time to ensure the reliable operation of the device.
  • Electrical Conductivity: While not always the primary function, armature springs may also serve as conductive paths and thus require good electrical properties.
  • Fatigue Resistance: Armature springs are subject to repeated cycling and must resist fatigue to maintain their mechanical properties.
  • Stability Under Stress: The material used for armature springs must perform reliably under various stress conditions, including mechanical, thermal, and environmental stresses.

Application of High Conductivity BeCu Alloys in Armature Springs:


  • Function: In relays, armature springs return the armature to its resting position, ensuring that the contacts can open or close the circuit when the relay is energized or de-energized.
  • BeCu Benefits: BeCu alloys provide the necessary combination of springiness and fatigue resistance to ensure the long-term reliability of the relay.


  • Function: Solenoids use armature springs to return the plunger or armature to its original position after the magnetic field is removed.
  • BeCu Benefits: The resilience of BeCu allows the solenoid to operate consistently over a large number of cycles.

Electric Motors:

  • Function: In certain types of electric motors, armature springs may be used to ensure good contact between the commutator and brushes or to maintain tension in other movable components.
  • BeCu Benefits: BeCu’s excellent electrical and mechanical properties help maintain efficient motor operation and extend service life.

Circuit Breakers:

  • Function: Armature springs in circuit breakers are part of the tripping mechanism that opens the circuit in response to fault conditions.
  • BeCu Benefits: The reliability of BeCu ensures that circuit breakers will function properly when needed, which is critical for safety.

Considerations for BeCu in Armature Springs:

  • Material Grades: Different grades of BeCu are available to match the specific requirements of the application, such as higher conductivity or greater mechanical strength.
  • Heat Treatment: Heat-treating BeCu can enhance its mechanical properties, making it more suitable for the demands of armature spring applications.
  • Design and Geometry: The design of the armature spring, including its shape and size, will affect its performance and must be optimized for the specific application.
  • Surface Treatment: Plating the BeCu armature springs with noble metals can improve their resistance to corrosion and wear, as well as enhance electrical conductivity.
  • Compliance with Standards: Armature springs, especially those used in safety-critical devices, must comply with relevant industry standards and regulations.

By using high-conductivity BeCu alloys for armature springs, manufacturers can ensure that their electromagnetic devices perform reliably and efficiently. BeCu’s unique combination of electrical and mechanical properties makes it an ideal material for the repeated and precise movements required in these applications.
