Tungsten

W

Tungsten is a natural, rare element. In pure form, it is a silver white metal that is very dense and nearly impossible to melt. Tungsten isn’t just dense, but it is also known for being the third heaviest solid state metal in the world. Its hardness and durability give it many applications including being used for armor piercing military grade projectiles and industrial catalysts. Often used in jewelry, tungsten carbide is an alloy made from carbon and tungsten that is more easily shaped than its pure form.
