C109 Copper (CW118C)

Copper Alloy


C109 Copper Alloy

C109 (CW118C) is a free-machining, oxygen-free copper.



Improved Machinability

The introduction of Tellurium content raises the machinability of the alloy considerably (to 90%); this increase in machinability does not impact on conductivity or ductility performance. C109 is not susceptible to hydrogen embrittlement and has good hot and cold workability. To add further value, we process all your copper grade material in-house.



Characteristics

C109 (CW118C) copper benefits from exceptional machining qualities and excellent electrical & thermal conductivity. With good hot and cold workability, C109 is not susceptible to hydrogen embrittlement.



Typical Applications

Commercial applications for this engineering material include:

  • Complex and intricate electrical components
  • Electrical switches
  • Circuit breaker terminals
  • Transformer terminals
  • Connector pins
  • High currency carrying components
  • Clamps
  • Bolts, nuts & studs

We stock C109 in flats, round bar and square bar.
