Heated tungsten
A heated filament made from the metal tungsten. Much in the way that an incandescent lightbulb works, the high voltage that is fed through the filament causes electrons to be kicked off the filament. The amount of energy required is known as the work function.

Lanthanum hexaboride (LaB₆)
The LaB₆ filament is also a thermal filament. However, its work function is lower than for a tungsten filament, so it is more efficient.

Tungsten field emission gun (FEG)
The FEG gun is not a thermal filament. Instead, electrons are expelled by applying a very powerful electric field very close to the filament tip. The size and proximity of the electric field to the electron reservoir in the filament causes the electrons to tunnel out of the reservoir.

How often do you clean your Tungsten darts? Or any of your darts for that matter?

If you haven't been cleaning them, then I can assure you that they are probably already corroding. This is especially important after eating any salty or greasy snacks. How often have you munched on some chips or salted pretzels while you were playing?I will be the first to admit..... I do it all the time!

Then I found out that these oils and salt were slowly corroding the barrels of my darts. I thought that the ridges on them were smoothing out due to the darts bumping into each other all of the time, or hitting the floor (every once in a while. lol) but in fact, the stuff on my hands was causing far more damage than bumping each other or hitting the floor every could.

Now I clean my darts often and nothing special is needed to do this, so, why not right?Any mild cleaner that can remove oil will do. Hand soap, household cleaners, and even moist towelletes (not the ones that contain hand lotion!) will work fine. If you need something to take along to tournaments or league play, small alcohol swab packets are handy.

With this little bit of extra care, your darts will last even longer for you!

Are Tungsten darts thinner than other darts? In fact, yes they are!

Tungsten darts are (based on the percentage of Tungsten involved) more dense than brass and copper darts. Since they are more dense, they are able to be thinner, but still the same weight.The benefits of having a slimmer dart is one that will become very important to you as you begin to get more experienced with playing and challenging others and here is why:

Just think about this scenerio. Your right at the end of a game and you know that if you would hit two bullseyes, you would hands down win the game. You throw with your brass dart and you hit the bullseye. Yay! Now your about to throw your second dart, but the space remaining on that bullseye is decreased by your large brass dart sticking out of it. At times like this, you would much rather be using a slimmer dart!

Carbide end mills often do not come with flats machined on the shank to use in CNC tool holders. By using a diamond wheel and a bench or manual grinder, you can make your own flat for the screw that holds the end mill in place when using just such a holder. Taking small amounts of material at a time will prevent heat build-up and damage to the diamond wheel, resulting in a perfect flat every time.

Tungsten carbide is created when tungsten and carbon are combined in equal amounts. In order to create tungsten carbide, the process has to be carried out at temperatures between 1,400 and 2,000 degrees centigrade. The resulting product, tungsten carbide, has an extremely high melting point of about 5,200 degrees Fahrenheit and a low electrical resistance, meaning it readily conducts electricity.

Since it is much harder and denser than steel, tungsten carbide, when used on drills, is able to drill through more rock and have a longer lifetime than steel drills. Tungsten carbide is also used as a machine cutter to cut through steel and other metals.

There is no comprehensive comparison of tungsten carbide between and among tungsten carbide suppliers.  A big part of the problem is the huge number of suppliers, grades and trade names.   There are at least 5,000 different grades of mtungsten carbide sold under more than 1,500 different trade names by more than 1,500 different companies.  Refer to our Carbide and Advanced Material Index for more information on Carbide Material.

There is no true standard.  The US "C" designation, The ISO designation and other designations are not necessarily relevant.  Tungsten carbide from two different manufacturers may have identical designation but vary widely in almost every imaginable way including performance.

When darts claim to be made of Tungsten, take notice to the percentage of Tungsten that they have in them.

Tungsten darts are not 100% Tungsten but rather a Tungsten/ Nickel alloy. The bigger the percentage of Tungsten, , the denser it will be and generally the more expensive the dart is. An 80% Tungsten dart would have 20% Nickel in it. These darts can range anywhere from 70 to 95%.

Be aware that you may see alot of Tungsten darts for sale at a very cheap price and although they claim to be Tungsten, the percentage of them is actually very small. Anything less than 70% will pretty much lose all of the benefits of Tungsten, so I would stay away from them if you are looking for any kind of durability.When the dart is super dense, like lets say it is a 90% Tungsten, it will also be very hard. Sounds great at first right?

Well keep in mind that if you happen to have a lot of bounce outs (which happens alot with soft tip darts!) or your dart hits the floor often for one reason or another, the higher percent Tungsten will be more likely to break, versus a 80% which would have a bit more "give" to it. It will still be durable and it will wear down slower if it is at least 80%.

The majority of dart players find that the 80% Tungsten darts are a great choice for them in both soft tip and steel tip varieties.

Tungsten carbide measures a nine on Moh's hardness scale, meaning it is about as hard as corundum, but not as hard as diamond. In order to polish or finish an item made of tungsten carbide, a diamond must be used because any other metal or mineral would crack and break. Only a diamond is hard enough to be able to scratch tungsten carbide. Its density also surpasses the density of titanium.
