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.

Iridium is a platinum group metal with atomic number 77. Ir is very hard and brittle metal with silvery color. Iridium has great corrosion resistant even at high temperature as 2000C. Iridium is an ideal material for tip of spark plugs and has been used to make crucible for artificial crystals manufacturing

A crucible is a container that can withstand very high temperatures and is used for metal, glass, and pigment production as well as a number of modern laboratory processes. While crucibles historically were usually made from clay, they can be made from any material that withstands temperatures high enough to melt or otherwise alter its contents
