A family's day with Tungsten

When he starts the motor, he remembers what a business partner has mentioned, that so called cemented carbide tools for machining the engine block are very good business and use a strange element called Tungsten as their main constituent. Perhaps he will look for stocks of such a tool company to invest his saving.

The motor is a diesel engine, but one could barely feel that. He is really happy about his new 10cylinder engine-almost no vibrations. What he is not aware of is that almost 10kg of Tungsten heavy metal parts, located around the crankshaft are responsible for the perfect vibration damping.

He enters his car. It is an icy morning and he is happy to have Tungsten filaments in the front and rear windows. Quickly the ice on the windows is removed and he is grateful for the unobstructed view.

Window heating system in the car

tungsten wires are used for car lighting but also for window heating; tungsten wires are also used for charged (corona) wires in laser printers or copying machines; thicker wires are used as evaporation coils for the metallizing industries.

So early in the morning it is good to have this old styled 15W incandescent lamp on his table. The warm and gentle colour of the Tungsten Filament in the lamp makes it easy to get up.

In the bathroom he needs of course a more intense light, to shave closely for the business trip (it isn’t weekend, when he sometimes doesn’t shave at all). A set of Halogen spots with high performance Tungsten wires supply the light.

Dressed up, he passes quietly the rooms of the kids where an energy saving lamp- with electrodes made from Tungsten- has burnt the whole night. The little daughter is still so chicken- hearted, he thinks to himself.

tungsten is used in the form of wire, coils, coiled coils or electrodes in most of the modern lamp systems; power ratings are from a few watts to several thousand watts (lighthouse lamps; up to 10kW).

The story on a family’s day with Tungsten

Father:

It is early morning and the father has to leave for a business trip. This trip is really important and he doesn’t want to oversleep. On the other hand the alarm clock would be too loud and awake his wife and he knows that she has an appointment at the hospital and is already nervous and needs to sleep well. So he adjusted the vibration alert of his mobile phone and put it under the pillow.

Now he is awakened by the gentle vibration of a small Tungsten part rotated by an electric micro motor inside his handy phone.

Mobile phone with dismantled vibration alert;

the vibration are caused through a small unbalanced-mass motor made of tungsten heavy metal. The high density of this alloy (up to 18.5g/ cm3) renders an excellent size to vibration power ratio.

Tungsten-in our daily life

Our daily life is closely connected with the element Tungsten. Modern life would not be possible in the way it is without the unique properties of Tungsten, as they are:

• the highest melting point of all metals (3422℃)
• a high density like Gold (19.3g/ cm3) and
• a hardness close to Diamond, as Tungsten Carbide (WC)

scheelite(tungsten ore)

Although Tungsten has such outstanding properties it is curiously more or less unknown to the majority of people.

Then let’s accompany a typical family with father, mother, daughter and son for one day to see how they run across Tungsten during their normal daily activities either directly or indirectly and frequently even without realizing it.

Advantage of Tungsten Dart Billet

Advantage of Tungsten Dart Billet 

The advantage of tungsten dart billet is: in the same weight, the brass dart barrel is very thick, but the tungsten dart barrel is much slimmer. Because darts suffer more closely, the space of triple area becomes larger, this is very favorable for a good darts players. Tungsten dart have more obvious advantages compared to the traditional brass. In addition to the small deformation, they can also be produced great knurled pattern on the barrel. This provides a stronger grip, and reduces the potential skid situation.

The weight of the tungsten dart is between 16 grams to 30 grams. Before decided to buy a set of darts, as much as possible to try a variety of darts is very important. The most important thing is you feel very comfortable when you throw the dart. Once you find the perfect set of darts. It is best to buy the same sets extra to prevent this set of darts lost or stolen. If your device is a bit old, or you want to improve, to replace your darts is a good idea.

What's（tungsten）dart billet?

What’s（tungsten）dart billet?

Dart billets are the rods use to make dart barrels.

Now, in the sports, the standard material of dart barrel is tungsten heavy alloy, and dart barrel is the main part of the dart. Dart billets are cylindrical tungsten rod after surface grinding by center-less processing, and there are many kinds of weight according to the different tungsten content and rod sizes.

Tungsten dart billets in various sizes and tungsten content. The 70~90% tungsten dart billets are widely used in the manufacture of soft tip and steel tip darts, and the weights ranging from 14~18 gram and 18~40 gram respectively. But sometimes, according to customer's special requirements can also provide the 65% and 95~97% tungsten dart billets.

However, there are steel tip darts with two threads too, and they are usually used for “movable tips”. This kid of darts can reduce bounce outs. Although these darts are intended for use in steel tip darts, as long as to replace the tips with soft tips, then they can also be used for the soft tip darts.

On the other hand, most of the soft tip darts can be equipped with such movable steel tips. Not all of the soft tip darts can be equipped with such movable steel tips, because the system requires a deeper thread.

For example, the Unicorn's Hammer Head system can be used for ordinary soft tip darts, but Harrows' Power Point system can not.

The compatibility of the dart barrel means you can replace the dart shaft by another dart shaft products by different companies to connection on the barrel.

The dart barrel can be used in both steel tip dart and soft tip dart. The "classic" steel tip darts have solid attached tips, that means they can not be used for the soft tip darts. The typical steel tip darts have fixed tip on one side and thread for fixed flight on the other side.

Soft tip darts have threads both of two sides. One side is used for fixed plastic tip, and the other side is used for fixed shaft. If you replace the plastic tip to the steel tip, the barrel can be used in steel tip dart. These replacement tips have a variety of shapes.

Dart barrel weight

Dart barrel weight

There are a lot of people want to know that they which weight they should throw, which weight is the most common one, what is the average weight, etc. These questions there are no absolute correct answers. For the "average weight" issue, there may be an answer, but it does not make much sense.

Giving an example of two world champions:

Dennis Priestley throws 14 gram darts.

Raymond van Barneveld throws 26 gram darts.

For beginners, we recommend using the darts of the weight between 22 to 25 grams. This is a slightly heavy weight. The reason is that you need to train in the basic skills of throwing in the initial level on the heavy side. You may feel, throwing the lighter darts progress a little faster, but lighter darts can not force you to train a decent technique which to improve it will suffered many difficulties in the future.

Once you get a throwing experience and a decent technique. Then you may find that is not convincing because of the kind-hearted of heavy darts. If you think that you can throw the dart more flexible, then you should consider throwing lighter darts.

Soft tip darts players will not have much choice on the weight of darts. Because of the limit set by the machine operators and leagues, the weight of the soft tip dart is usually less than 20 grams. If you are a beginner of soft tip darts, the only advice we can give is to training from the maximum allowable weight.

Dart barrel threads

Dart barrel threads

Dart barrel threads are known as "2BA" which follows the British standard. The old-fashioned brass darts tend to have 1/4 inch thread. These two threads are not compatible. Only the old-fashioned brass darts have 1/4 inch thread, standard shafts or soft/movable tips are equipped with 2BA thread. Generally, the thread incompatibility problems would not happen.

If you buy a new set of darts, to see whether the old spare parts can be used in your new darts. When you buy your first set of good darts, try to attach inexpensive standard spare parts instead of the original packaging ones. 

 

Dart barrel surface

Dart barrel surface

Dart barrel surface is covered with knurled pattern or rings, which provide a more powerful grip. And there are a variety of painted or unpainted styles. This for dart barrel surface shape offers a variety of different choices. Dart barrel surface may be also very common, usually beginners do not like. But it can not be said that the changing pattern is the best one. The most suitable dart barrel surface pattern for your is the one you use comfortable.

However, the painted surfaces you should not to try. Paint pattern may looks good, but this makes the dart more slippery. The only exception is the Unicorn's "gold" brand. This darts are covered with a golden coat (it do not know what material this coating is, but it is not real gold), according to them, which can improve grip. It seems that some people like them. 

To try and find out the best darts for yourselves.

The advantage of tungsten dart barrel

The advantage of tungsten dart barrel

Tungsten dart barrel have different kinds of types, including W-Ni-Fe, W-Ni-Cu, W-Ni-Cu-Fe, etc. At the same time, the mature technique of surface grinding and centre-less processing can produce darts according to customers' special design. Also have many advantages such as easier to score, therefore, tungsten dart barrel are more and more popular around the world now.

In the same weight, the brass dart barrel is very thick, but the tungsten dart barrel is much slimmer. Because darts suffer more closely, the space of triple area becomes larger, this is very favorable for a good darts players. Tungsten dart have more obvious advantages compared to the traditional brass. In addition to the small deformation, they can also be produced great knurled pattern on the barrel. This provides a stronger grip, and reduces the potential skid situation.

The shape of darts

The shape of darts

The main shape of the dart are cylinder, ton and torpedo.

The shape of some darts can be selected on the left are barrels with 2 threads (soft tip), on the right are fixed-tip steel dart barrels.

This is not to say what shape is the "right" one. Based on the theories, the most suitable shape of darts may be the long cylindrical barrel, because it is the slimmest and allows the tightest grouping. For the 140S and 180S is very good. But if you do not like to use this type of darts, the statement is not helpful. It is a matter of personal preference that to select the darts shape. Choose the darts that make you feel most comfortable when handle them. This is more important than the theoretical discusses the advantages or disadvantages of some darts shape.

The size of dart barrel

The size of dart barrel

Size is usually the first factor to consider when people buy darts. In the same weight, tungsten alloy darts only about half of the diameter of the copper darts, which makes two or more tungsten alloy darts easier to hit a double or triple area.

Think about that, at the end of a cricket game, you need to hit several bull's eye to finish. If using the old-fashioned fat brass dart, the first dart would almost covering the bull's eye. But replaced by a thin tungsten alloy dart, two or three darts hit the bull's eye will be much easier.

Tungsten dart billet is the rod used to manufacture dart barrel. The standard material of the barrel is tungsten heavy alloy, while the barrel is the main part of the Darts.


The darts content of very high tungsten,such as 98%, with a dense feel and the surface resistance to abrasion for a longer time. However, high concentrations of tungsten powder also makes them brittle and easy to break if dropped on a hard surface such as garage floor.
