Specifications

Tungsten alloy rod have very high melting point and density which are twice than steel and more than 50% heavier than lead.

Tungsten alloy rod have very high melting point and density which are twice than steel and more than 50% heavier than lead, which is important in the case of needing high weights while low volume. What's more, tungsten alloy rod has high density and high tensile strength, separately ranging from16.5 to18.75 g/ cm and 700 to 1000Mpa. In addition, tungsten alloy rod has good corrosion resistance, weld ability, mach inability and low thermal expansion. Besides, tungsten alloy rod is wearable, resulting in prolong the life of the tungsten alloy crankshaft rodwhich is so important to companies for saving of regular cost. Finally but not the lastly, tungsten alloy's harmless to health and environment-friendly which is important in this decades also leading people to adopting tungsten alloy materials for their crankshaft counterweight. The above advantages have made tungsten alloy rod ideal materials for crankshaft.

The tungsten alloy crankshaft rod is a rotating mass, and any rotating mass that isn't perfectly balanced will cause uneven loading on the bearing surfaces that support it. The faster it turns, the worse the problem becomes. So we should not overlook the importance of balancing the engine, as it enables us to sustain higher engine speeds and gives us reliability.
Followings Are Pictures of Tungsten Alloy Crankshaft Rod:

Tungsten Alloy Crankshaft Rod-02
The tungsten alloy crankshaft rod bearings fit into the lower end of the connecting rod. they are fed a constant supply of oil through a hole in the crankshaft Journal. A hole in the upper bearing half feeds a passage in the connecting it to provide oil to the piston pin.

Reducing engine vibration reduces stress on motor mounts and external accessories, and in big over-the-road trucks, the noise and vibration the driver has to endure mile after mile. A smoother-running engine is a powerful engine as less energy is wasted by the product as tungsten alloy crankshaft thrashes about in its bearings, which translates into a more usable power at the flywheel.

However, we must also remember that no engine can be perfectly balanced as the amount of factors involved which we can not find out. But we can certainly improve upon choosing the more ideal materials introduced above for tungsten alloy crankshaft rod counterweights.

During the late 1950s, tungsten carbide was the primary material used for kinetic energy, armor-piercing projectiles. When first fielded, tungsten carbide represented a quantum improvement over its nearest competitor, high carbon steel. Its higher density (approximately 13 gm/cc) gave it superior penetration performance against existing armor targets. With the advent of double and triple plated armor in the 1960s, however, tungsten munitions showed a tendency to break up before penetrating the layered armor. This deficiency spurred the development of new alloys and materials capable of defeating any armored threats.

In response to the new operational requirements, military developers evaluated a succession of metal alloys. Initially, the British government developed a higher density tungsten alloy consisting of 93 percent tungsten and 7 percent binder tungsten alloy (WA). The new WA alloy had a density of 17 gm/cc -- versus 13 gm/cc for tungsten carbide. From 1965 to 1972, the US Army conducted a parallel development program for the 152mm XM578 cartridge, which was co-developed with the prototype MBT-70 Tank. The XM578 cartridge used a tungsten alloy that was slightly denser than the British alloy, consisting of 97.5 percent tungsten and 2.5 percent binder, which had a density of 18.5 gm/cc.

Picatinny began to research upgrades to the penetrator in the early 1950s. They eventually led to the revolutionary development of accurate, long-rod, fin stabilized penetrators encased in aluminum sabots that filled the full diameter of the inside of the barrel and were capable of defeating the heaviest tank armor. By the mid 1960s, Picatinny's efforts concentrated on a very high pressure, smoothbore cannon in a 120mm caliber and on experimental fin stabilized projectiles. These used a variety of sabot designs and a new penetrating material, depleted uranium (DU). There were difficulties with sabot integrity and excessive gun wear, but the program showed that very high pressures were feasible, that such pressures were essential to greatly improved performance and that DU could be used as a structural material as well as an efficient penetrator.

In the 1960s, tungsten alloys used in the XM578 projectile had to be encased in a steel jacket to withstand the extreme firing velocities of the 152mm gun, reducing the penetrating effectiveness of the tungsten cartridge. The new U-3/4Ti alloy overcame these early limitations for large caliber munitions.

The primary effort at Picatinny during that time period was the development of the XM578 kinetic energy round for the new 152mm cannon. A strategy was devised that called for combining ultra-lightweight plastics with titanium sabot components, with the DU material that acted as both a structural material and as the penetrator body. These were combined with a plastic driving and sealing band that allowed insertion of the much longer KE cartridge several feet down the rifled bore of the new cannon.

With the terminatlon of the Program and the initiation of the XM-1 Tank Program, a need for a modern 105mm Anti-tank, Kinetic Energy Projectile. Picatlnny Arsenal responded to this tasking by utilizing the technology gained in the 152nwn Program - specifically the subpEojectile - and adapting it to the 105mm Gun by means of a saddle sabot.

Throughout the 1960s and early 1970s, the US Army developed a successive series of improved 105mm rounds (the primary caliber of the main gun on M-60 and developmental XM-1 series tanks) using the denser 97.5 percent tungsten alloy. The XM735 and XM774 cartridges were the first rounds developed out of the XM578 cartridge program.

A decision analysis was performed on the XM578 APFSDS projectile development program in 1973. The decision analysis differed from a Risk Analysis in that, along with assessing program risks, the decision analysis proposed alternative program approaches and compared the expected outcomes of the proposed alternatives with the basic program. Prime consideration was given to the quantification of uncertainties, examination of allocation of resources between test and design phases of the development program and to quantify the value of information obtained in a test program.

What is tungsten heavy alloy golf weight?

A golf club head includes one or more balance weights for swing balancing the golf club. The balance weight is selected from a plurality of balance weights and mounted in a weight cavity formed in the golf club head.

Tungsten alloy is now well known as the best material for this significant role of golf club balance weight. You can have a general impression for how tungsten alloy is applied to balance the golf club’s better control from the below pictures demonstration.

Tungsten heavy alloy for golf weights

Owing to their unique properties, tungsten alloys are well suited for use as weights for sports equipment. Tungsten heavy alloys have a density twice that of steel and weigh seven times more than aluminum.

Tungsten alloy inserts allow manufacturers to focus the weight in their golf clubs. This process has lead to improved launch, spin and forgiveness.

Recent innovations have also increased the usage of tungsten in the sport. Some claim that because tungsten is dense and the center of gravity more centrally located, a tungsten core will create more spin in golf balls.

Tungsten Alloy Aircraft Weight Application

As far as we know, in the large modern ships, the keel often made ​​or fitted with such materials with high specific gravity material such as lead. But lead is easy to produce pollution, due to the high proportion of tungsten materials and non-toxic, tungsten alloy has increasingly been used the weight of the vessel. This weight placed on the more low (usually at the bottom of the keel) more able to maintain the balance of the boat. Traditionally used sand or stone.

What is crankshaft?

The crankshaft, sometimes casually abbreviated to crank, is the part of an engine which translates reciprocating linear piston motion into rotation.

How does crankshaft work?

The rods and bearings connects the piston to the crankshaft, when the piston moves up and down, the crankshaft is moved as describing a circle by the rods and bearings, then, the crankshaft is rotating.

Advantages for tungsten alloy crankshaft

Nowadays, modern engine is often made from special metal alloys, and much lighter than earlier engines. So the powder and performance of a modern engine are increased. Also,
It is necessary to provide counterweights for the reciprocating mass of each piston and connecting rod to improve balance in engines, and these are typically cast as part of the crankshaft. Lead is cheap but the density is much lower than tungsten heavy alloy, and it is not environmental friendly, as for steel, tungsten heavy alloy are more than twice the density of it, so compared with other materials, tungsten heavy alloy is certainly considered t as the most appropriate crankshaft material for its properties as follows:

Small volume but high density

Excellent hardness

Superior wearing resistance

Good corrosion resistance

Wonderful Shock resistance

High melting point

High temperature resistance

Environmental friendly

Tungsten eye shield can use either the 0.5 mm or 1 mm thick anodized aluminum cap (both are included with each tungsten eye shield) to reduce the electron backscatter to the eyelid. Tungsten eye shield can be used without the aluminum cap when placed superficially. Tungsten eye shields have less transmission than other eye shields.
 
The 2 mm tungsten eye shield is recommended for use with 6 MeV. The 3 mm tungsten eye shield is recommended for 9 MeV. These tungsten eye shields are not recommended for use above 9 MeV. The user will have to determine an acceptable amount of backscatter to decide whether to use 0.5 mm or 1 mm aluminum cap.

Technology implemented at over 40 percent of the operating nuclear power plants in the United States is now being used to help in the efforts to contain the stricken reactors at the Fukushima Daiichi nuclear power plant in Japan.

Tungsten shielding, first developed in 2006 with a partnership between Entergy Nuclear and American Ceramics Technology, has been used by Entergy employees since 2008 for protection from radiation while performing maintenance during refueling outages. The shielding is a flexible heat-resistant material made of tungsten and iron metal powder immersed in a silicone polymer.

Traditionally, lead has been the product of choice for radiation shielding. Tungsten shielding has the ability to field-fit, providing for attenuation of radiation totaling from 5 to 10 person-Rem/year than provided by the equivalent weight of traditional lead blanket. And since tungsten is thinner and weighs as much as 50 percent less than lead, it may be more forgiving when workers are performing the physical activities required in a nuclear power plant.

"It gives them better protection at a lighter weight and better mobility," said Dick Culbertson, CEO of American Ceramics Technology.

Vests made of tungsten worn by employees working in areas where there is exposure to radiation were successful when first used, but did have limitations. The vests had the ability to protect only the front of the body, so the source of radiation had to be directly in front of the worker. Then, American Ceramics Technology received a request from the 810 MW Cooper Nuclear station, which Entergy provides support services to, for a vest that covered the entire body, front and back. Workers at Cooper were entering areas of the plant that had a high dose field coming from all directions.
