Berylco® 14 - Beryllium Copper Alloy

Berylco® 14 (also known as Alloy 3) is a high conductivity beryllium copper alloy which is ideal for applications requiring a combination of strength with high thermal conductivity. Offering corrosion-resistant characteristics similar to pure copper, Berylco® 14 is fully heat-treated, and therefore, no further treatments are required. The resulting material is non-magnetic and thermal fatigue is excellent. The general machinability and brazing characteristics of the alloy is also good. Weldability of the alloy is considered to be only fair though Berylco® 14 is highly weldable to copper.

The material is stronger when compared to other copper alloys with superior structural strength.

Motorsport / Automotive Uses

Traditional applications for Alloy 3 include oil and gas applications, particular in long-reach power and signal solutions. Due to the materials high conductivity and strength, Berylco 14® also offers a variety of motorsport and automotive applications which include:

  • Engine compartment connectors
  • Switches
  • Sensor terminals
  • Coaxial connectors
  • Signal connectors
  • Any environment where a degree of thermal management is required

We stock Berylco® 14 in bar, plate and wire


Berylco® 14 resists stress corrosion cracking in both sulphide and chloride solutions. It is corrosion resistant to most organic solutions, saltwater atmosphere, non-oxidising acids and diluted alkalis and is not susceptible to hydrogen embrittlement. Use with strong oxidising acids or ammonium hydroxide is not recommended.

Product Benefits

  • High electrical conductivity
  • Superior strength when compared to other copper alloys
  • Good resistance to stress relaxation
