Tellurium Copper


Farmer’s Copper Ltd. is a C14500 Tellurium copper round rod supplier. C145 Tellurium is adapted for use in high-speed automatic screw machines. The copper telluride precipitations become finely dispersed throughout the matrix and assist in chip breakage 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 ensuring longer tool life. The high conductivity of tellurium copper makes it a suitable material for electrical applications and is an outstanding alloy for the production of hot forged products.
