Product Description
As we know, the barrel forms the main part of a dart, which is key factor of determining weight and quality of 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.
Today's standard material for barrel is tungsten heavy alloy. 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.
