Tellurium copper is tellurium and copper alloy and a kind of tellurium bronze materials, this kind material contains 0.4-0.7%’s tellurium, which makes tellurium copper alloy have good machining performance; Copper telluride containing 50% tellurium and 50% copper is used as an intermediate alloy. In ASTM standard it is named C14500, In GB standard named QTe0.5, In JIS named C1450, in DIN named CuTeP and in BS it is named C109. C14500 tellurium copper alloy is with high conductivity and free cutting copper alloy material, its development is aim to fill the gap of copper alloy precision processing materials. C14500 tellurium copper alloy material has both good free cutting performance and excellent electrical& thermal conductivity, meanwhile it is with good corrosion resistance and electric ablation resistance. Besides, C14500 tellurium copper has good cold and hot processing performance, can be forged, cast, extruded, drawn and molded by punching.
