The density of tungsten carbide needles is about 15~19 g/cm³, depending on the content of tungsten in the tungsten steel and the ratio of other alloy components. Generally speaking, the higher the tungsten content in tungsten steel, the greater the density. Because tungsten steel has excellent characteristics such as high density, high strength and high hardness, it has been widely used in many fields that require high strength and high hardness, such as aerospace, electronics, military and other industries.
