Copper anneal in the semiconductor industry.

Conductors are usually made of copper or silver wire. In high- end cables, the copper's purity is important. Copper is sometimes specified as containing some percentage of "pure" copper, with the rest impurities. For example, a certain copper may be 99.997% pure, meaning it has three-thouhs of one percent impurities.

Copper Vs. Silver Wire Conductivity | Sciencing

Though silver wire is roughly 7 percent more conductive than a copper wire of the same length, silver is a significantly rarer metal than copper. Combined with silver's tendency to oxidize and lose efficiency as an electrical conductor, the relatively minor increase in conductivity makes copper a more sensible option in most scenarios.

Thermal Conductivity of Copper | Chemical Properties of Copper

Copper is renowned for being a good conductor of electricity and heat. This happens because the delocalized electrons lying inside the solid lattice of metals have the freedom to move freely in their lattice. These would act as the transporters of heat and electric charge from one end to the other and turn the metals into good conductors.
