    High quality tellurium copper bar C14500 ASTM B301


    Tellurium Copper's (TeCu) resistance to hydrogen embrittlement combined with its' high electrical and thermal conductivity make it the ideal choice for electrical applications requiring extensive machining, corrosion resistance, or for the production of hot forged products.


    The cutting properties of copper are enhanced significantly by creating a copper alloy with the addition of .5% tellurium (C145 Tellurium) which is adapted for use in high-speed automatic screw machines. On a machinability rating scale with 100% equal to free-cutting brass, Copper 145 Tellurium has a machinability rating scale of 85-90%, compared to pure copper which has a machinability rating scale of approximately 20%. The results? Increased efficiency on manual and automatic production lines as well as a significantly longer tool life!



    Chemical Composition:

    Cu+Ag: min 99.90%
    P:  0.004-0.012%
    Te: 0.40~0.70%
