Types of Beryllium-Copper Alloys

The physical and mechanical properties of beryllium copper alloys are significantly influenced by the amount of beryllium and other alloying elements, as well as the specific heat treatment procedures employed by manufacturers. For buyers and engineers seeking to source or specify beryllium copper, understanding these distinctions is crucial for making an informed decision. Beryllium copper alloys are broadly categorized into two main types: high-conductive beryllium-copper alloys and high-strength beryllium copper alloys. The following sections provide a detailed breakdown of each type, including their compositions, key characteristics, and typical applications.

High-Conductive Beryllium-Copper Alloys

High-conductive beryllium copper alloys contain a lower percentage of beryllium, typically ranging from 0.2% to 0.7%. These alloys may also include small amounts of cobalt and nickel to further enhance their conductivity. As their name suggests, these alloys excel in electrical and thermal conductivity, making them particularly well-suited for demanding applications in the energy, electronics, and automotive industries.

• C17510 or Alloy 3

  Alloy 3 is utilized in applications requiring moderate strength, excellent resistance to thermal fatigue, and high electrical conductivity. With a composition of 1.4% to 2.2% nickel and 0.26% to 0.6% beryllium, C17510 is widely specified for use in resistance welding electrodes, power transmission contacts, and high-current switchgear parts where heat dissipation and mechanical reliability are critical.

  

• C17500 or Alloy 10

  This alloy features a beryllium content of 0.4% to 0.27% and a higher cobalt content of 2.4% to 2.7%. The elevated cobalt level imparts slightly reduced thermal conductivity and melting point compared to C17510, while maintaining excellent strength and hardness. Both C17500 and C17510 are known for their high electrical and thermal conductivity, making them ideal for electrodes, connectors, and components in automotive ignition systems, aerospace connectors, and industrial power distribution systems.

High-Strength Copper Alloys Made of Beryllium

High-strength beryllium copper alloys are engineered for applications demanding maximum mechanical strength and durability. With beryllium content ranging from 1.6% to 2.05%, these alloys deliver exceptional hardness and tensile strength, making them suitable for heavy-duty and precision applications across aerospace, defense, automotive, and telecommunications sectors.

• Alloy 25 or C17200

  The strongest and hardest among beryllium-copper alloys, C17200 (Alloy 25) combines a tensile strength of up to 200 ksi with a beryllium content of approximately 2%. This alloy exhibits steel-like strength while retaining remarkable corrosion resistance and conductivity properties. Alloy 25 is frequently used in plastic injection mold tooling, precision springs, high-load electrical contacts, aerospace fasteners, and critical components where both strength and thermal management are vital. Notably, C17200 lowers the temperature of plastic molds during injection, eliminating the need for additional cooling water and reducing production cycle times.

  

• Alloy M25 or C17300

  C17300, also known as Alloy M25 or "leaded beryllium copper," contains a small lead addition (0.2% to 0.6%), which enhances machinability without significantly compromising mechanical strength or conductivity. This makes C17300 ideal for manufacturing complex, precision-machined components such as electrical connectors, instrument contacts, fasteners, and bushings, especially in high-volume production environments where tight tolerances and repeatability are essential.
