Literature value. Copper uses: Before end-use copper is manufactured into semi fabricated products, such as shapes and ingots (known as 'semis'). These manufacturing processes are subdivided into hot working, cold working and, if necessary, process annealing. Few of the semis are ready for use as such. They more typically travel to first-stage manufacturers, who make metal rods, wire, and casting, and then to component manufacturers who produce such things as motors, valves, and insulated cables The components in turn are incorporated by final-stage manufacturers into a variety of finished products - automobiles, commercial buildings, residential housing, and so forth. These uses account for about 79% of the world-wide consumption of copper.
