Metal Strip and wire for electronic connectors in Pfinodal® C72900  - copper nickel tin alloy as an alternate to beryllium copper BeCu

Electronic Connectors

Electronic Connectors

Our highly specialized Spinodal materials are custom-engineered for electronic connectors and deliver major advantages in comparison to traditional materials such as Beryllium Copper (BeCu). We offer precision strip and wire products in alloy Pfinodal® (UNS C72900), a copper nickel tin Spinodal alloy, for the manufacturing of high performance electronic connectors in the electronics industry.
Safe Alternative to Beryllium Copper (BeCu)
Beryllium Copper (BeCu) materials are the historical choice for electronic connectors. Our high performance Pfinodal® (UNS C72900) delivers similar mechanical properties to Beryllium Copper but without the harmful exposure risks.
Advantages of Spinodal Alloys for Electronic Connectors
A major benefit of Pfinodal® (UNS C72900) is the lack of stress relaxation during heat treatment following forming of parts. As compared to Beryllium Copper alloys (BeCu), the Spinodal C72900 materials maintain tolerance much better when undergoing the final heat treatment step which allows manufacturers to more closely tolerance parts. Further, parts in service in harsh environments maintain their shape at higher temperatures ensuring that electronic contact is maintained and minimizing unplanned downtime for equipment. AMETEK Specialty Metal Products offers the age hardening treatments of formed parts as well as offering mill-hardened products direct from the plant. Further benefits include:
  • Ductile state and heat treatable
  • No carcinogenic elements - Only Copper/Nickel/Tin
  • Electrically conductive
  • Reduced distortion during heat treatment
  • Reduced stress relaxation
Nickel Strip for Electronic Connectors
Additionally, AMETEK SMP has been a leader in the production of high purity Nickel Strip for use in battery tab and battery connectors. This high purity product enlists a 15% higher conductivity compared to standard cast products which include resistive non-metallic inclusions. The high conductivity of our nickel products makes it the choice for demanding electronic applications.
