Both the planned Franco-British support of Finland in the Winter War, and German occupation of Denmark and Norway (Operation Weserübung) were partly motivated by control of the nickel mines.

Nickel is a vital component in the production of Steel Alloy. Alloy steel is steel to which additional alloying elements have been intentionally added to modify the characteristics of steel.

Nickel and manganese in steel add to its tensile strength and make the austenite form of the iron-carbon solution more stable
