How Rare is Tungsten?
Tungsten Statistics. Tungsten ranks at #74 on the list of most abundant elements in the Earth's crust. The estimated abundance of tungsten in the crust is around 1.5 parts per million, or about 1.5 grams per ton of rock. This makes it over 10 times more rare than copper. Tungsten is thought to make up about 1 ppm of the Earth's mantle.
