Why billets & darts are made of tungsten heavy alloy?
As we know, the barrel forms the main part of a dart. Nowadays, tungsten heavy alloy billets 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 heavy alloy barrels 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 heavy alloy darts have a characteristically slimmer barrel. Due to these special properties, tungsten is now widely applied in the making of darts to replace brass.
Today's standard material for barrel is tungsten heavy alloy, and tungsten heavy alloy barrels forms the main part of a dart (mainly used in sports). Tungsten has a specific gravity of 19.3(20 ℃ ), so it is a very dense material. For its special properties, nowadays tungsten is widely applied to make darts replacing brass. Because of technical difficulties with manufacturing, a 100% tungsten dart is not available. All "tungsten" darts you can buy are in fact made of tungsten heavy alloys.
We could supply tungsten heavy alloy 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.
