Description

Advantages of tungsten alloy:

 

Tungsten alloy has many special properties, such as small size with high density, high melting point, high hardness, excellent wear resistance, high ultimate tensile strength, good extension, heat resistant, good thermal stability, easy processing, corrosion resistance, good shock resistance, high radiation absorption capacity, excellent impact and crack resistance.

Tungsten alloy dart billets Introduction:

Tungsten dart billets are the rods used for making dart barrels. 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 ℃ ), 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 alloy.

We could supply tungsten dart billets by various sizes and contents, popularly 70~90% tungsten dart billets are used for making both soft-tip and steel tip tungsten barrels, ranging from 14~18 gram and 18~40 gram respectively, and sometimes, 65% and 95~97% tungsten are offered following customers’ specific request.
