Tungsten alloy is an excellent material to manufacture tungsten alloy crankshaft counterweights in motorbike. All engines need perfectly balanced crankshafts to ensure optimized performance. If a crankshaft is not correctly balanced, the consequences can be severe. 

Counterweight is an integral part of a variety of big machines dealing with huge load. By balancing the weight, it secures a safety performance of tractors, trucks, cranes, excavators and others. If you own a truck that you want to have a safe trip, it is important that you do not just go out into the wild with the equipment that came with your vehicle. Even Jeeps usually require special upgrades to ensure that they are able to handle driving on terrain that is not paved. Failing to ensure that you have the right elevation and counterweight in your truck, tires or wheels can lead to expensive damage. Tungsten alloy counterweight is the best choice in truck to ensure the balance of weight when loading and unloading goods.

Tungsten alloy counterweight is used to counterbalance an opposing mass in a linear or rotary motion system, allowing movement with lower driving forces. Tungsten alloy can be used as an ideal material for counterweight in elevators. Heavy metal tungsten alloys are 90% to 97% pure tungsten in a matrix of nickel and copper or nickel and iron. The addition of these alloying elements improves both the ductility and machinability of these alloys over non-alloyed tungsten. 

Tungsten oxide electrochromic film has great application value in the field of building energy-saving glass due to its real-time adjustment of indoor lighting and thermal insulation. It is considered as the next generation energy-saving window material to replace Low-e coated glass.

The heat-shielding properties of their films were investigated by near infrared spectrometer. Synthesized Cs0.33WO3 particles with annealing at 800 ℃ typically formed hexagonal tungsten bronze structure for good absorption of NIR, size observed as being 30-100 nm and <150 nm. Especially, remarkable absorption of NIR wavelength ranges makes ceramic composite films good candidate for use as a heat shielding window, it clearly shows useful for applications where heat shield is required.

Nanowhiskers, nanowires and nanorods are nearly perfect materials, which have superior performance compared with metal materials. As a structural material, tungsten whiskers or tungsten nanowires are used to reinforce and toughen refractory alloys, ceramic materials, etc. Can significantly enhance the toughness and strength of the material.

Tungsten alloy gains a great deal of popularity in fishing sinkers thanks to its non-toxicity. Tungsten is a rare element of very hard and dense metal. Lead has the density of 1.7 times of water, while tungsten 19.3 times of water. It is mined in only a few areas around the world, China is the biggest producer of tungsten. 

In the last article, we talked about the brief history of darts and the fact that tungsten alloy got more and more popular in darts. Now let’s have a deeper understanding of the application of tungsten alloy in darts.

1.0 The Importance of Dart Weight

The introduction of tungsten darts revolutionized the game, and this is not an exaggeration. Tungsten darts allowed two mutually interrelated things to happen. As darts became smaller, they also became heavier, and heavier darts radically improved player’s scores! A tungsten dart, being heavier than a brass or plastic dart, will fly through the air in a straighter line and with more force; which means bounce outs are less likely to happen. Therefore, heavier darts provided players with more control during the throw and made tighter grouping more likely. Anyone that knows about the intricacies of darts scoring systems will tell you about the importance of being able to place darts in tight groups consistently. Being able to place darts in tight groups consistently will make you an overall more balanced player of the game. Not being able to hit 180s all the time is not so bad when you can knock down a checkout on demand and hit doubles all the time.

2.0 The Perfect Metal for A Dart Tungsten Percentages and Composition

Tungsten darts are not a one size fit all affair, there are quite a few options when it comes to choosing to purchase a tungsten dart. Because of the chemical properties of the metal and various practical reasons during manufacture, darts made of tungsten are not 100% pure. Heavy metal alloys made of tungsten and nickel are used: with nickel-iron and nickel-copper matrices being the most common. These heavy metal alloys allow for enhanced machinability and permit manufacturers of darts to offer products with higher rigidity, lower vibration, higher damping, and reduce thermal expansion properties.

The most common compositions available on the market are:

• 65% Tungsten – 35% Nickel

• 80% Tungsten – 20% Nickel

• 90% Tungsten – 10% Nickel

• 95% Tungsten – 05% Nickel

• 97% Tungsten – 03% Nickel

3.0 The Perfect Metal for A Dart

One of the most defining characteristics of tungsten metal and its alloys is its density. Tungsten density is almost twice that of lead and is comparable to that of uranium. For those of you who do not remember your high school science lessons, density is a function of mass and volume, which means that a substance with a high-density value can have a smaller size while maintaining the same mass. In laymen’s terms, if you have two objects of equal weight but with different densities, the denser object will also be the smaller. A 30-gram dart made of tungsten will be approximately half the diameter of a 30-gram dart made out of brass!

Some people will say that tungsten darts should not be recommended to beginners and that only advanced players and professionals benefit from the added control; however, anyone who is serious about getting better at the game should invest in tungsten darts from the get-go.

Even though tungsten darts are more costly to make and therefore a more expensive purchase, the benefits that this most important of metals provides cannot be easily dismissed.

A dart’s point, barrel, shaft, and flight can all be made out of various materials, each with different advantages and disadvantages. There are over 90 metals in the periodic table and perhaps hundreds of metal alloys known to man, yet most darts are made of tungsten. Why are darts made of tungsten alloy?

Tungsten alloy armor piercing shell is a type of ammunition designed to penetrate armor. From the 1860s to 1950s, a major application of armor-piercing tungsten projectiles were to defeat the thick armor carried on many warships. From the 1920s onwards, armor-piercing weapons were required for anti-tank missions.
