This is not the first time that this has been a problem.

In WW2 all sides needed more tungsten, hence: https://en.wikipedia.org/wiki/Wolfram_Crisis

As a side note, Tungsten is a Swedish word ("heavy stone"). It was first "discovered" by a Swede, and they called it Tungsten. Its atomic symbol is W, for wolfram, the German word for it, which even the Swede's use. I find it mildly amusing. (it is to do with tungsten rich ores and the name of the ores that had been known about for a while)
