Product Description

C14500 Tellurium Copper (Deoxidized Grades)

Spec Equivalents: ASTM B301, ASTM B124, Free-Machining Copper

C145 Tellurium Copper (TelCu) has applications in the production of hot forged products, high-speed screw machine products and parts requiring high conductivity, extensive machining, corrosion resistance, copper color, or a combination of these. The addition of tellurium enhances the strength of the copper alloy and assists in chip breakage, allowing for much higher machining speeds and ultimately longer tool life than with pure copper in high-speed screw machines.

Typical Applications:

  • Gas cutting nozzles
  • High-speed automatic screw machines
  • Electrical Switches on power semiconductors
  • Welding Torch tips
  • Transformer & Circuit-breaker terminals
  • Fasteners
  • Production of hot forged products
