A. Plastic Tooling & Molds


Beryllium copper plate and rod wrought products are utilized in the plastics processing industry for plastic injection molds, blow molds, cavity inserts, and associated production components such as manifolds and nozzles. The material is specified in these applications due to it combination of high strength and hardness coupled with excellent thermal conductivity (as compared to tool steel and aluminum). The material performance properties of beryllium copper provide the tangible benefits of improved cycle time and piece part quality with the assurance of ongoing superior wear and durability characteristics.



Beryllium copper high strength wrought alloy (C17200), in a fully age hardened condition, attains tensile strength properties in the 200 ksi range with a Rockwell C45 peak hardness. This strength/hardness combination is the highest available when compared to any of the other copper based alloys. In industrial oil and gas applications beryllium copper alloys provide critical components with important performance characteristics: non-sparking/non-magnetic, superior wear and anti-galling properties, high hardness and strength, high fatigue strength and toughness, plus good corrosion resistance.


 

Beryllium copper alloys improve component service life, enhance durability, and reduce maintenance by imparting superior galling and friction wear characteristics in commercial and military aircraft landing gear bushings and bearings. Aerospace applications utilizing beryllium copper do so for the materials:

D. Electronics and Telecommunications


Beryllium copper strip alloys have historically been specified in electronic connector applications in an impressive array of telecommunications, computer, and automotive electronics applications. Beryllium copper rod is utilized to produce certain machined connector designs and beryllium copper casting alloys are specified for intricate miniature investment cast connectors. Undersea fiber optic cable repeater housings and their associated components have been specified in beryllium copper for many years. These beryllium copper housing assemblies (wrought and cast components) must perform flawlessly, for an extended service life measured in decades, in the harsh deep water marine environment of the world’s oceans. Obviously, beryllium copper’s special combination of corrosion resistance, high strength, and durability characteristics match the severe operational requirements.

 

Evolving electronics technology, and its subsequent application in cell phones, personal data devices, computers, and peripherals, is requiring higher reliability, increased performance materials. Beryllium copper alloys, and special hybrid beryllium copper/beryllium nickel alloys, are meeting these demanding application requirements. High strength and conductivity, excellent fatigue and wear properties, and wide variety of available material configurations and fabrication technologies, support beryllium containing alloys as strong material candidates for today’s electronic applications.

E. Resistance Welding


 

The high conductivity beryllium copper rod (C17510, 17500) is utilized to produce resistance welding equipment components (shanks, adaptors, holders, etc.).

Beryllium copper rod, plate and bar are specified for welder dies, welding wheels, and associated resistance welding components. Weld gun robots on automotive assembly lines make millions of individual welds utilizing sand cast beryllium copper C17510 weld gun arms (one of the primary structural components of the weld gun arm assembly on the robot). Beryllium copper is the material of choice for these applications because of its excellent elevated temperature fatigue strength combined with high strength/high hardness and electrical/thermal conductivity properties.
