A long time ago Wolframite was used for Tank Armour in World War 2 as it is very strong and not the easiest to break.
Wolframite is an important Ore of tungsten. This means that it is highly desired by mineral collectors.
Tungsten or its alloys are used for filaments for electric lamps, electron and
television tubes, electrical contact points for automobile distributors, heating
elements for electrical furnaces, and space, missile, and high-temperature
applications.
