Beryllium Copper

A reliable source for Beryllium Copper information and leading Beryllium Copper Companies & Manufacturers.

To improve a metal’s qualities, it is mixed with another metal or other non-metal elements to form an alloy. Beryllium copper (BeCu) is a metal alloy of copper which is achieved by adding beryllium (ranging from 0.5% to 3%). Typically beryllium is added to increase copper’s strength. The specific grade of beryllium copper depends on the ratio of beryllium to copper and each grade has other beneficial characteristics. Read More…

Beryllium Copper Beryllium copper is the strongest, most durable copper alloy that contains anywhere from 0.5 to 3% beryllium, an alkaline earth metal that is mainly used as a hardening agent in alloys.

The distinction between these grades is made based on their conductivity and strength. As one of the greatest strength copper-based alloys, this alloy is used in all industrial sectors. In addition to their high strength, different grades of beryllium copper exhibit other qualities, such as superior conductivity and non-magneticity, that make them appropriate for a variety of industrial applications.

Traditionally, machine parts and tools have been made of this alloy. Today, it may now be used in electronics and other fields because of improved casting, enhanced machining, and other developments that have made this alloy suitable for various applications.

Properties of Beryllium Copper

Beryllium copper and its assortment of alloys exhibit many beneficial characteristics including:

  • It provides superior thermal and electrical conductivity.
  • Beryllium copper’s high ductility and outstanding formability are essential with regards to machining, forming, and metalworking processes.
  • It is non-magnetic.
  • Beryllium copper is suitable for use in hazardous or combustible conditions since it is non-sparking. As a result, the mining, petroleum, and oil-drilling industries now employ it frequently.
  • It is more durable than the majority of copper alloys and resists wear and galling (another form of wear caused by sliding surfaces).
  • It retains its beneficial characteristics in very high or very low temperatures.
  • This material provides greater corrosion/oxidation resistance than steel.
  • It is suitable for activities involving precipitation-hardening used to help create even-stronger super alloys.
  • Beryllium copper has a high tensile strength: Beryllium copper is the strongest copper alloy, with a maximum load-bearing capacity of around 200,000 pounds per square inch. This strength can be further increased through precipitation hardening (also known as age hardening).

Types of Beryllium-Copper Alloys

The amount of beryllium, along with other alloying elements used, and the heat treatment procedures used by the manufacturer all have a significant impact on the physical qualities of a specific beryllium-copper alloy. Based on their composition and the intrinsic physical characteristics they display, beryllium copper alloys are categorized into two types: high-conductive beryllium-copper alloys or high-strength copper alloys made of beryllium. We discuss each of these categories below.

High-Conductive Beryllium-Copper Alloys

These alloys have a lower beryllium concentration, ranging from 0.2% to 0.7%, as well as minute amounts of cobalt and nickel. These alloys have a high degree of electrical and thermal conductivity, as their name suggests.

  • C17510 or Alloy 3

    It is utilized in applications that have a need for moderate strength and resistance to thermal fatigue. C17510 contains 1.4% to 2.2% nickel and 0.26% to 0.6% beryllium.

    alloy 3 beryllium copper
  • C17500 or Alloy 10

    This alloy has a beryllium content of 0.4% to 0.27% percent and a higher cobalt content of 2.4% to 2.7%. The higher cobalt marginally reduces the thermal conductivity and melting point of C17500. The qualities of C17500 and C17510 include high electrical and thermal conductivity, strength, and hardness as their defining characteristics.

    alloy 10 beryllium copper

High-Strength Copper Alloys Made of Beryllium

For heavier-duty applications, the beryllium content ranges from 1.6% to 2.05% in high-strength copper alloys. The increased level of beryllium is what provides these beryllium alloys their extraordinary strength. Examples of high strength beryllium copper alloys include:

  • Alloy 25 or C17200

    The strongest and hardest of the beryllium-copper alloys, C17200 or Alloy 25, possesses a hardness and strength comparable to steel. It has a tensile strength that can reach 200 ksi and includes 2% beryllium. C17200 lowers the temperature of the mold when introduced into a plastic mold, negating the requirement for cooling water.

    alloy 25 beryllium copper
  • Alloy M25 or C17300

    C17300 shares many of the same characteristics as C17200. Alloy M25, also referred to as "leaded beryllium copper," additionally contains a minute portion of lead (ranging between .2% and .6%), which makes it machinable for use in manufacturing, particularly in the fabrication of precision parts.


As previously discussed, beryllium copper has numerous characteristics beneficial for a variety of applications. Some specific areas where beryllium copper may be found include:

  • As electrodes used in resistance welding and spot welding
  • In components of vehicles and communication satellites
  • As springs & spring wires
  • In nozzles for injection machines
  • In metal die casting
  • As plunger tips
  • In molding inserts and in plastic injection
