Tellurium copper rod is an alloy material primarily composed of copper with the addition of tellurium (typically in a content of 0.4% to 0.7%). The core advantage of the tellurium copper rod lies in its balanced combination of multiple key properties.  Its electrical conductivity can reach over 85% IACS, and even exceed 95% IACS in some cases, approaching the level of oxygen-free copper; its tensile strength is generally in the range of 350-450 MPa, and its moderate hardness facilitates machining processes such as turning and milling, producing easily manageable chips that do not readily adhere to the cutting tool; it also possesses good corrosion resistance and arc erosion resistance, exhibiting high stability in humid or corrosive environments.
