Norwegian aluminium and wider Scandinavian imports

Norway's wartime aluminium capacity expanded dramatically under occupation, which raises the question of how much equivalent expansion a British-linked Norway could finance. The exact production path is uncertain, but Germany loses Norwegian aluminium, lubricants, heavy water, and other inputs while Britain gains access to them. Tungsten, nickel, and Swedish ball bearings add further industrial effects beyond aircraft metal. Short, covered Norwegian supply routes would also be easier for Britain to protect than long transatlantic imports.
