Today’s standard material for barrel is tungsten heavy alloy, and barrel forms the main part of a dart (mainly used in sports). Tungsten has a specific gravity of 19.3(20¡æ), 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.

WCu alloys are used worldwide for EDM (Electrical Discharge Machining) and ECM (Electrochemical Machining) electrodes. All material is manufactured by the press, sinter, and infiltrate process. Virgin powders are used, resulting in a consistent homogeneous material giving high and even burning rates. Copper tungsten is used in plunger/sinker applications where intricate definition is required, especially in tungsten carbide.
