The international aluminium market represent a specific case in the process of "commodisation" that characterised the pre-1914 period. Unlike the other non-ferrous metals, whose origins are lost in the midst of the time, aluminium was a new and high technology material. On the one hand, the international aluminium market was prematurely born as global, in spite of the national legal monopolies that derived from the patents on its technology. On the other hand, aluminium escaped from the control of the traders that characterized the global trade of other non-ferrous metals. The early aluminium market was developed through a specific marketing activity, settled on the structure of an international cartel. The competitive edge of this metal became the price stability, which was chosen by the cartel board and which make it different from the commercial approaches adopted by other commodities and, in particular, by non-ferrous metals.
