Tellurium Copper Bar

Farmer’s Copper Ltd. inventories C14500 Tellurium copper round rod. C145 Tellurium is classified as a free-machining copper. The copper telluride precipitations in the microstructure effects the cutting chips into short pieces, thus enabling a much higher machining speed than with pure copper. Copper 145 Tellurium has a machinability rating scale of 85%, compared to pure copper of 20%, thus longer tool life. The high conductivity of tellurium copper makes it a suitable material for electrical applications.

Typical application for C14500

  • Electrical Switches on power semiconductors
  • Welding Torch tips
  • Transformer & Circuit-breaker terminals
  • Fasteners
