Tungsten heavy alloy billets are the rods used to make dart barrels.
Very high percentages of tungsten, such as 98% tungsten darts, have a wonderful dense feel and a surface that resists wear for a long time. However, the high concentration of tungsten powder also makes them brittle, and more prone to break if dropped on hard surface such as a concrete garage floor.
To get around those problems, most tungsten dart billets are now made of mixtures ranging from 70% to 95% tungsten. Lower density barrels are much cheaper, as they are easier to manufacture with automated machinery Low density darts also wear faster, from skin acid, friction, hitting other darts, falling on floors, etc.
Tungsten has a specific gravity of 19.3(20 ℃ ). 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 alloy.
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.
