As we know, the barrel forms the main part of a dart. Nowadays, tungsten-based heavy alloy billet is widely used as the standard barrel material, for it has a specific gravity of 19.3(20℃), making it a very dense material with small volume. Besides, it has superior wearing resistance, well machinability, etc.
Since its special properties, tungsten alloy darts billet for darts is quite difficult to be manufactured as 100% tungsten. Therefore, in fact, the "All- tungsten" darts in market are made of tungsten alloys. Engineered for a greater weight to volume ratio, tungsten darts have a characteristically slimmer barrel. Due to these special properties, tungsten is now widely applied in the making of darts to replace brass.
我We could supply tungsten alloy darts billets by various sizes and contents, popularly 70~90% tungsten is used for making both soft-tip and steel tip barrels, ranging from 14~18 gram and 18~40 gram respectively, and sometimes, 65% and 95~97% tungsten are offered following customers' specific request.
Billets are actually tungsten cylinder rods after surface grinding by center-less processing, and their weights are varied from different tungsten contents and rod sizes.
