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.

The sport of darts remains an incredibly popular game, very easy to play when out or at home. For the uninitiated, however, there are lots of options when it comes to selecting the right kind of equipment. Darts themselves are made with a variety of materials, weights and tips, each with their own advantages and disadvantages

The cost of your darts may influence your choice. Brass and steel barrels tend to be cheaper, so if you are buying a set for the first time to see whether you enjoy the game, you might wish to try these before committing to the more expensive tungsten darts, which can sometimes be 2-3 times as expensive.

Although the original question asked whether steel darts were better than tungsten, the answer is probably that a combination is best. Professional darts players will typically use tungsten barrels and steel tips.

No matter what the professionals do, however, nothing is more important than how comfortable you are throwing the darts when choosing them. Go to a shop which stocks a variety and they will usually allow you to try them. Experiment with differently weighted darts, different alloys and pick a set which feel right in your hand.

The sport of darts remains an incredibly popular game, very easy to play when out or at home. For the uninitiated, however, there are lots of options when it comes to selecting the right kind of equipment. Darts themselves are made with a variety of materials, weights and tips, each with their own advantages and disadvantages

 In order to fly effectively, darts need a certain amount of weight behind them. The main part of the dart, the barrel, is usually made with metal alloy. Steel and tungsten are both used, as are brass and silver/nickel alloys. The advantage of tungsten over all other types is its density, meaning the dart can be quite weighty while still being slim. This is useful if you throw your darts in close groupings to one another on the board. Fatter shafts will tend to bounce off of other darts and may miss their intended target or even bounce off the board.

When it comes to selecting a tip for your darts, the board you play on is the critical factor. The tip of the dart is either made from steel or a soft tip. The steel is weighty enough to stay in the bed of the traditional bristle dartboard. Soft tips are essential for use on the electronic dartboards.

According to the statistics, from 2003 to 2011, China’s tungsten ore reserves decreased from 4.2 million tons to 1.9 million tons with the decline of 54.8%. Calculated in accordance with the production capacity in 2010, the current reserves only own 23 years of mining life. “China’s Oil, Gas and Solid Mineral Resources Reserves in 2012”, which was issued by the Ministry of Land and Resources, note that the newly-added tungsten ore was 841,000 tons in 2012.

According to the statistics of China Nonferrous Metals Industry Association, the output of tungsten concentrate was 124,706 tons in 2012, increased by 122,000 tons over 2011 with the growth rate of 2.25%.

In 2011, the revenue growth rate of tungsten ore smelting enterprises was higher than cemented carbide enterprises, and the industry-wide sales revenue exceeded CNY 70 billion with the year-on-year growth of more than 40%. In 2012, the downstream demand was weak affected by global and domestic economic recession, which had a bad effect on tungsten ore market revenue; and the tungsten industry-wide sales revenue declined by 15.6% over 2011.

Huidian Research released “Research and Development Prospect of China’s Tungsten Ore Market, 2013-2017”, which mainly analyzes the market scale, technical status, market competition status, import, business performance of key enterprises, as well as the analysis and forecast of future development in the tungsten ore industry, which can provide enterprises and investors with decision-making reference.

China’s tungsten reserves account for 70% of the total global tungsten reserves; the output and export volume of tungsten ore have been ranked the first all over the world for a long time. However, the annual total tungsten mining volume is limited, so the tungsten supply is also subject to limitation. China’s tungsten ore has supplied the world at low price for long time, and 85% of world’s tungsten comes from China.

China’s tungsten resources are widely distributed in 23 provinces (autonomous regions), according to preliminary statistics, there are 382 tungsten ores in China, which mainly distribute in Jiangxi, Hunan, Guangdong, Yunnan, Guangxi, Inner Mongolia and Fujian. As for tungsten reserves, China’s tungsten resources mainly distribute in Hunan and Jiangxi. As far as the types of tungsten ore, China’s main type is white tungsten ore, followed by black tungsten and black-and-white mixed tungsten ore, the proportion is 69%, 22% and 9% respectively. As for different regions, Jiangxi is mainly based on black tungsten concentrate, Hunan is mainly based on white tungsten concentrate and Henan is mainly based on the byproducts of molybdenum ore.

A gray, inorganic material, tungsten carbide functions as a hardener in armor-piercing projectiles, the sharp edges of drills and saws, and cast iron.

Besides industrial uses, it is also used to create jewelry due to its hardness and deduced risk of allergic reactions among those with sensitive skin, among other desirable properties.

If you have read How Television Works or watched What If I Shot My TV?, then you have heard about electron guns. They sound a little bit like something out of "Star Wars," but they're actually the devices that are the heart of most TVs and computer monitors.

The idea behind an electron gun is to create electrons and then accelerate them to a very high speed. In a cathode ray tube (CRT) -- the big glass tube used in most televisions and computer monitors -- the electrons get aimed at the screen, where they light up the phosphor on the screen to create the image.

The electron gun starts with a small heater, which is a lot like the hot, bright filament of a regular light bulb. It heats a cathode, which emits a cloud of electrons. Two anodes turn the cloud into an electron beam:

• The accelerating anode attracts the electrons and accelerates them toward the screen.
• The focusing anode turns the stream of electrons into a very fine beam.
