Tungsten is a dense metal with a high atomic weight, which means that tungsten needles are relatively heavy compared to other materials commonly used for needles, such as stainless steel or aluminum. The density of tungsten is around 19.3 grams per cubic centimeter (g/cm³), which is more than twice as dense as steel (7.8 g/cm³) and almost three times as dense as aluminum (2.7 g/cm³).
As a result of their higher density, tungsten needles may provide certain advantages in applications where weight is a factor. For example, the weight of a tungsten needle can help it penetrate through tough materials or tissues with less force than a lighter needle. However, in other applications where precision or delicacy is required, a lighter needle may be more suitable.
