Tungsten is a very dense metal, with a density of around 19.3 grams per cubic centimeter (g/cm³) at room temperature. This makes it one of the densest elements in the periodic table, with a density that is about 1.7 times that of lead, another dense metal.
Compared to other materials commonly used for needles, tungsten is much denser. For example, stainless steel has a density of about 8 g/cm³, which is less than half that of tungsten. Similarly, titanium has a density of about 4.5 g/cm³, which is less than a quarter of the density of tungsten.
The high density of tungsten is one of its key properties that makes it useful for applications that require high strength and resistance to deformation, such as in the production of tungsten needles, filaments, and other high-performance components. However, the high density of tungsten also makes it more difficult to work with and more expensive than some other materials.
