What Is Beryllium Copper?

Beryllium copper (BeCu) is a copper-based alloy containing a small percentage of beryllium and, depending on the alloy, other elements. In beryllium copper metal stamping, this material is valued for its:

• Exceptional strength and elasticity

• High electrical and thermal conductivity

• Resistance to fatigue and corrosion

  
  

These properties make BeCu ideal for producing precision components that must withstand dynamic forces and harsh environments.

Why Choose Beryllium Copper for Metal Stamping?

Beryllium copper metal stamping provides performance advantages not easily matched by other materials:

• Superior Strength: Hardness up to 45 Rc, surpassing 301 stainless steel.

• Electrical Conductivity: Critical for efficient energy transfer in connectors and contacts.

• Fatigue Resistance: Maintains performance over repeated cycles.

• Corrosion Resistance: Performs in automotive, aerospace, and medical environments.

  Applications of Beryllium Copper Metal Stamping

• 
  

  At Advanced Metal Technology, we use beryllium copper metal stamping to create high-performance parts like:

• 
  

  • Electrical Contacts & Connectors: Conductive components requiring spring properties and repeatable contact force.

  • Custom Flat Springs & Spring Clips: Precision formed components for dynamic assemblies.

  • Battery Contacts: Conductive components requiring spring force, corrosion resistance, and reliable electrical contact.

  • 
    

  Using fourslide and multi-slide metal stamping, we form BeCu into complex, tight-tolerance parts quickly and efficiently.

Heat Treatment for Beryllium Copper Metal Stampings

Example: Beryllium Spring / Electrical Connectors

In beryllium copper metal stamping, proper heat treatment is essential to achieve required mechanical properties. Common cold-worked tempers include:

• TD01 (1/4 Hard)

• TD02 (1/2 Hard)

• TD03 (3/4 Hard)

• TD04 (Full Hard)

  
  

After forming, BeCu components can be age hardened to achieve higher strength and the required final mechanical properties. Our in-house age-hardening process helps maintain dimensional control and production consistency.

Copper Nickel Tin: An Alternative to Beryllium Copper

For some applications, we recommend C72900 (Copper Nickel Tin) as an alternative material. For some spring and electrical contact applications, C72900 copper-nickel-tin can be considered as an alternative to beryllium copper.

• High strength and good spring properties

• Beryllium-free alloy

• Good resistance to stress relaxation

• Can provide good dimensional stability during age hardening

  
  

Our engineers can evaluate whether C72900 suits your specific stamped component needs.
