The values listed above represent reasonable approximations suitable for general engineering use. Due to commercial variations in composition and to manufacturing limitations, they should not be used for specification purposes. See applicable ASTM specification references.

​

C14500 TELLURIUM COPPER is adapted for use in high-speed automatic screw machines. The copper tellurium precipitations become finely dispersed throughout the matrix and result in small chips enabling a much higher machining speed than with pure copper. C14500 tellurium copper has a machinability rating scale of 85%, compared to pure copper of 20%, ensuring longer tool life. Resistance to hydrogen embrittlement combined with its' high electrical and thermal conductivity make it the ideal choice for electrical applications requiring extensive machining and corrosion resistance. C14500 Tellurium Copper conforms to specification ASTM B301 , SAE J461, J463, B-124​​​
