Tungsten Dart Billet

Tungsten is a very dense material, so darts with a considerable weight can be made slim.Billets are actually tungsten cylinder rods after surface grinding by center-less processing, and their weights are varied from different tungsten contents and rod sizes. Tungsten is used in dart production because of its high weight to volume ratio. The higher percentage of tungsten used to make a dart which is the slimmer and sleeker. Tungsten billet is the raw material of barrel which forms the main part of tungsten dart.

Nowadays, lots of people are like to buy the tungsten very much, because of there are advantage for using.

The higher the percentage, the slimmer the dart will be, resulting in increased higher scoring chances. A90 % tungsten darts will be slimmer than an 80 %.

Tungsten – Titanium dart billet.

The dart billet made by tungsten-titanium, this is tungsten darts with titanium . This is the most expensive darts on the market today.
The titanium dart makes the darts harder, better gripping and it's worth a try.

Brass darts billet
The dart billet made by brass, this type of darts is cheap and can be a good investment when you start throwing darts. You can try out different shapes, weights and it does not cost as much as nickel and tungsten darts. It's also available in most designs torpedo, cylinder etc.

Chrome Dart Billet
The dart billet made by messing-chrome, this is messing darts with chrome alloy and the darts have some better grip. This type of darts is often used by advanced players. The barrels are a little bit smaller than regular brass darts.

Tungsten – Dart Billet

Nowadays, tungsten-based billet is widely used as the standard barrel material, for it has a specific gravity of 19.3(20℃), making it a very dense material with small volume. Besides, it has superior wearing resistance. The dart billet made by tungsten, today tungsten darts is used by most professionals; the barrels have a slim design and are made for great grouping in the dartboard. When you buy a set of tungsten darts billet ,it's often 80% tungsten and up to 97% tungsten the higher the percent is the thinner the barrels are, and of course higher price.

Chrome Dart Billet
The dart billet made by messing-chrome, this is messing darts with chrome alloy and the darts have some better grip. This type of darts is often used by advanced players. The barrels are a little bit smaller than regular brass darts.

Also commonly termed APT, it is the "mother salt" or fundamental intermediate for downstream manufacturing of most tungsten materials and is used in tungsten-bearing catalysts. APT is quoted on the LME where its price is used as the precursor for the tungsten market.Ammonium paratungstate is a white crystalline powder having a minimum WO3 content of 88.5%, it is traded in container loads and priced in USD/mtu WO3. Its composition is typically:

WO3  =88.5%

Mo  <0.002%

Others  <0.001%

Also commonly termed AMT. It is has higher water-solubility than APT which suits its predominant application in tungsten-bearing catalysts. It is also a white crystalline powder of up to 99.95% purity AMT.Two grades are used in the industry having WO3 contents of minimum 83% and 90%.AMT is generally priced in USD/mt of material based on its WO3 content.

The hydrogen and tungsten content and the high solubility of ammonium metatungstate suggest that a saturated aqueous solution of this salt may make a good neutron-gamma shield for 252Cf. Comparative attenuation experiments with a saturated aqueous solution and pure water show that the ammonium metatungstate solution is a significantly better shielding material for gamma rays and slow neutrons, and is also better than water for fast neutrons. For 252Cf sources of less than 500 [mu]g, a shield consisting of a thick paste of ammonium metatungstate is recommended as a useful shielding material in place of a saturated solution to reduce the hazard in case of container leakage. A saturated solution of ammonium metatungstate is relatively clear and may be used as an absorber in windows of hot cells.

The interaction of nickel hydroxocarbonate, ammonium paramolybdate, and ammonium metatungstate (Ni:Mo:W= 3: 1:1) is reported.Under mechanical activation conditions, nickel hydroxocarbonate particles undergo comminution and ammonium paramolybdate and ammonium metatungstate particles soften and aggregate.It is demonstrated by DTA,X-ray diffraction and IR spectroscopy that heat treatment of the mechanically activated mixture at400–450°C yields the salts NiMoO4 and NiWO4.Nickel Hydroxocarbonate, Ammonium Paramolybdate and Ammonium Metatungstate
