Tungsten Dart Billets are basically rods that are widely used for making dart barrels. Tungsten has a specific gravity of 19.3(20 ℃ ), hence it is very dense. Apart from this, tungsten has some special properties that make it the best option for making darts replacing brass. Tungsten Dart Billets are basically tungsten cylinder rods after surface grinding by center-less processing. The advantage of using tungsten in the dart billets is that you can achieve the same weight as a thick brass barrel with highly slim design.
