Cleavage of Tungsten

Tungsten is found mostly in four different ores: scheelite, wolframite, ferberite, and huebnerite. Of these four, wolframite is the principal ore for tungsten and the only one not too brittle to measure its cleavage.

The cleavage of wolframite is perfect, numerically noted as (010), and indicates that wolframite breaks cleanly in one direction.
