In western countries, an increasing share of metals is imported. While the supply of metals used in everyday products requires to be reduced, many economic sectors could be considerably affected. A distinction should be made between base metals (iron, copper, zinc, lead…) and rare metals, little known to the general public, and yet at the heart of high

FINNISH NICKEL AS A STRATEGIC METAL, 1920–19441
Scandinavian Journal of History, 2007Petsamo nickel in Northern Finland became a bargaining chip in the Great Powers' political game before and during the Second World War. ‘Weak states’ such as Finland had room to pursue their own interests both in the cartelized interwar military markets and especially during the Second World War. Despite the common assumption of weakness on the part of
