C14500 Tellurium Copper

ASTM B301

Specs
Level 4
Much Higher Machining Speed Than Pure Copper
Level 3
High Conductivity
Level 2
Longer Tool Life Than Pure Copper

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 affects 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.
