I. Product Introduction
C14500 tellurium bronze rod is based on a high-purity copper matrix, precisely alloyed with tellurium to retain copper’s inherent excellent electrical and thermal conductivity while significantly improving machinability and high-temperature stability. It offers an electrical conductivity of up to 85% IACS and a machining efficiency 1 to 2 times that of pure copper, with reduced tool sticking during turning operations, thereby greatly enhancing the cost-effectiveness of high-volume production.
II. Chemical Composition
Standards: DIN CuTeP/CW118C, UNS C14500.
