The most essential part of dart is dart barrel, which is the place held by people when throwing darts, and the dart's largest weight is on the dart barrel. 

Currently, the standard dart material is tungsten alloy. There are various types of tungsten alloy dart barrel that made of tungsten alloy dart shaft, including tungsten - nickel - iron dart barrel, tungsten - nickel - Copper dart barrel, tungsten - nickel - Copper - iron barrel, etc. 

 

High density is very important for darts, because high density darts can make the center of the dart more stable. It is necessary to do high precision machining of darts.

Tungsten is a metal that has high density and high strength.  

 

 

Mature surface grinding technology and centerless grinding technology can produce tungsten alloy dart barrel according to customer's special design. Because of the technical difficulties in manufacturing, 100% of tungsten darts are nonexistent. All the tungsten darts bought now are made of tungsten alloy, and the most common of them is nickel-iron-tungsten alloy.

 

The first factor in choosing a tungsten dart is its size. Tungsten alloy barrel density is higher than brass dart, and its diameter is much smaller than the brass darts. Tungsten dart diameter is half of the brass darts when they have the same weight. This compact and heavy weight dart will help us hit the bull's eye. Old brass darts target area almost is as large as the diameter. While tungsten alloy barrel with small diameter is more easy for two to three darts to occupy the bull's eye.

 

Tungsten alloy dart shaft is widely used in making dart barrel because of its high strength, high ray absorbing ability, good weldability and workability and other excellent properties. Tungsten alloy dart barrel is more and more popular around the world.
