Tungsten Dart Manufacture

As with most products, tungsten darts are not all the same. Raw tungsten does not melt easily, and is not readily made into machinable shapes. Tungsten is generally ground into a fine powder, which is then blended with a variety of other metals that act as binding agents. In the case of darts, the most common blends contain nickel, with smaller amounts of copper and ferrous compounds.  The mixture is heated and compressed to make a solid billet or bar, which can then be machined into darts barrels.

Within each percentage range of tungsten darts, there is a wide range of quality. Every company has its own special blend of metals that are combined to make the raw billets. The best darts for competition are also the most expensive to make and the most difficult to machine. Cheaper darts can be made by adjusting the blend by adding softer metals.  For instance, a bit more copper or iron may be added. A "softer" blend means that cheaper cutting tools can be used, the tooling won't dull as quickly, and the machinery can produce more darts in a given amount of time.

Different blends may also slightly change the appearance of the finished darts. Some darts look shinier; others have a more grainy appearance. Surface treatments during the manufacturing process can also make a great difference in the appearance of a new set of darts. A wide variety of coatings are often applied to darts barrels, ranging from simple paint or powder-coating to high-tech vapor-deposit coatings such as Titanium Nitride.
