WitrynaThe properties of Cu and Cu alloys can be enhanced by variations in composition and manufacturing methods. For example, lead (Pb) and tellurium (Te) can be added to Cu to improve machinability. Conversely, the presence of trace impurities in Cu and Cu alloys can adversely affect the properties of finished products. Witrynaimpurities can have major effects on the properties of the finished products, and in many cases it is desirable to minimize, or at least to be able to control, the levels of certain trace impurities. For example, the level of Ag and S in high-purity Cu wire may be required not to exceed 0.1 parts per million (ppm) [1].
