Description

2.1545 (CuTeP) is a free-machining grade of copper with an addition of around 0.5% tellurium. The tellurium content raises the machinability rating to 90% with minimal effect on conductivity and ductility. C109 has freedom from hydrogen embrittlement, enabling the use of this grade in electrical and electronic applications where accuracy and intricacy are required. It shows the following features and properties:


  • Enhanced strength levels over standard copper
  • Retention of properties at elevated temperatures
  • Outstanding machining qualities
  • Excellent electrical and thermal conductivity
  • Freedom from hydrogen embrittlement
  • Good hot and cold workability
  • Related Standards
