Tungsten Metal - Has very high density and melting point


Tungsten metal (aka wolfram) is a basic element with a density of 19.25 g/cm³, which is comparable to that of uranium and gold. It has a melting point of 3422°C, which is the highest of all the non-alloyed metals.

What is tungsten used for:

Tungsten is used in incandescent lightbulb filaments, where it emits bright light when heated to very high temperatures. It is also used in the form of tungsten carbide (compound with carbon) for wear-resistant abrasives and cutting tools. Tungsten is an effective radiation shielding material; it’s used in the nuclear industry as a non-toxic replacement for lead. Tungsten and gold have almost the same density and tungsten is used as a core material in counterfeit gold bars.


It is impractical to cast tungsten because of its high melting point. Instead, powdered tungsten is pressed to shape and sintered at a temperature much lower than its melting point.

The sample:

The sample is a rod with a diameter of 6 mm and a length of 95 mm. It weighs 51 grams.

All samples come with a laminated information card, which includes contact details for the supplier.
