Tungsten (W)

Last updated: March 22, 2017

What Does Tungsten (W) Mean?

Tungsten is a hard, heavy metal that is ideal for electrical conduction because of its high melting point. As a result, it is commonly used to make filaments in incandescent and halogen grow lights that are often used in areas where plants do not receive any natural light, such as during winter or indoors. Tungsten is one of the toughest metals in nature.

Maximum Yield Explains Tungsten (W)

Tungsten filaments in halogen and incandescent growing lights can replicate the sun’s light spectrum for indoor growrooms. Halogen lamps can actually reach far higher temperatures than other lamps such as gas-filled ones.

Additionally, Tungsten is an element (W) on the periodic table. It is so dense that this element is virtually impossible to melt. Scientists normally differentiate between natural and pure tungsten. Natural tungsten contains 21 unstable isotopes as well as 5 stable isotopes, while pure tungsten is a combustible silver-white metal. Pure tungsten is also extremely soft.

Tungsten has an impressively high melting point and is consequently used in a variety of ways. According to the Los Alamos National Laboratory, tungsten has a boiling point of 3,068.3°F and a melting point of 6,191.6°F. The primary sources of tungsten are found around the world in US states like Colorado and California, as well as the countries Portugal, Russia, Great Britain, and Bolivia.
