Just clean them with acetone, you don't really want to polish them as they will become slippy and slide out of your hand.
tungsten is a very strong and brittle metal. there are no darts made from 100% tungsten. it is always made with an alloy as tungsten is very brittle. the alloys are usually nickel, zinc and brass.
Tungsten darts are the most popular in the highly-competitive scene. They are pretty heavy, which allows for more accuracy (since the thickness of air wont have an effect), they're also smaller in the barrel, which allows for tighter grouping.
I know some people who paid hundreds of dollars for their darts. I think you can get a decent set of 80% tungsten darts for around US$40. If you're just starting to throw and not sure you want to spend so much at this point, you have the option of starting with brass darts. They're quite a bit thicker that tungsten darts, but they're a lot cheaper, too.
Darts come in a variety of materials, weights and grips. The most common metals used in the production of darts are brass, nickel silver and tungsten. Brass is inexpensive and is perfect for the home recreational player and the occasional pub game. Nickel Silver has the same attributes of brass but is tarnish resistant. Tungsten is extremely dense, three times denser than brass & nickel silver, and is popular because of its weight to size ratio resulting in a heavier weight in a smaller mass. If two barrels, one made of brass and one made of tungsten, the same weight were compared you would see that the tungsten barrel is 3 times smaller than the brass barrel. These important features make tungsten the material of choice for the more serious dart shooter.
There are a few advantages of using tungsten over gold for wedding rings. Tungsten is ten times stronger and harder than gold. Tungsten also has an incredible shine.
Tungsten shines for the same reason that any other metal shines; the metallic bond creates an electron cloud which readily reflects light.
The points of darts have traditionally been made of steel. In fact, the sport is often referred to as steel-tip darts, even though most points today consist of at least 80% tungsten (for added strength).
Tungsten and carbon
There are many uses for tungsten: Incandescent light bulbs: It makes up the filament of the bulb. It is used in the bulb because it can withstand extreme temperatures. Jewelry: The high scratch resistance and dark shine of tungsten makes it a very popular choice among men for rings and bracelets. Abrasive Coating: Many tools subject to cutting hard metals in harsh conditions are coated with tungsten. The high melting point and hardness of tungsten make it a valuable asset to machinery and cutting tools.
White light from a Tungsten filiment lamp is best. If you shine a small ray of the white light in one end a rainbow ray should come out the other.
