Tungsten Walking Fishing Sinkers

Details: Category: Tungsten Information; Published on Thursday, 11 September 2014 08:42; Written by Sherry; Hits: 559

These fishing sinkers are the bread and butter of many live-bait, walleye fisherman. They resemble a rectangle with rounded, outside edges. The top features an eye for the line. The fishing sinker's bottom is slightly wider and larger in size than the top, holding more weight. The bottom is also slightly rounded and bent upwards.

This weight distribution positions the sinker with its round edge on bottom, so it will easily glide over rocks, greatly reducing its changes of snagging on the bottom. The semi-flat design also prevents it from rolling along bottom in fast currents.

These sinkers are often used to drag live bait rigs along the bottom, and are sometimes called a live bait rig. To tie the rig, first thread the sinker on the line with the bottom bend pointing to the line's tag end.

Next, select a swivel large enough so it will not pass through the sinker's eye. Tie one end to your main line to the swivel. Then, you can add anything from a floating jig head, a plain hook, or a worm harness to complete the rig. This rig is not only snag-resistant, but it also allows line to slide through its eye when a fish picks up the bait.

This latter feature prevents a fish from feeling weight. Yet, when an angler keeps a tight line on the rig, the swivel will stop at the sinker's opening, allowing the leader's length to remain consistent and in the strike zone.

Application of Tungsten Alloy Ball

Details: Category: Tungsten Information; Published on Wednesday, 10 September 2014 16:23; Written by jwy; Hits: 594

Tungsten alloy ball is used as the hunting shot for shotguns. A shotgun is a firearm that is usually using pellet filled shells instead of using bullets. The shot pellets from a shotgun spread upon leaving the barrel, and the power of the burning charge is divided among the pellets, which means that the energy of any one ball of shot is fairly low. In a hunting context, it makes shotguns useful primarily for hunting birds and other small games.

Advantages of Tungsten Alloy Ball in Military

Tungsten alloy ball provide a safer, non-toxic and environmentally friendly alternative to lead. Their higher density enables them to hold their shape better, even under extreme conditions. While depleted uranium offers comparable density, its volatile nature and the special licensing requirements needed for radioactive materials make working with it difficult and expensive. We offers a variety of high-density alloys, available as ROTF (Rough, Over-sized to Finish) material, bars, spheres, plates or rods. We also have extensive machining capabilities, allowing us to provide crankshaft weights in standard sizes or custom products finished to your exact specifications.

Application of Tungsten in Modern Industry

Details: Category: Tungsten Information; Published on Wednesday, 10 September 2014 15:23; Written by jwy; Hits: 637

Tungsten is a silvery lustrous dense hard metal with the atomic number 74. Among all chemical component tungsten has the second highest melting point, while carbon having the highest. Even tungsten has the second highest boiling point comes after the metal rhenium and it is at the 8th rank in highest density that can be comparable to uranium and gold. Unlike the metal tin, aluminium or zinc, Tungsten has a very low toxicity.

The Average abundance of the material can be found in the continental Earth crust. The metal tungsten is widely used as hard metal in the form of tungsten carbide. It is indispensable for cutting and wears surfaces purposes like wood cutting, metal machining, petroleum exploration and mineral drilling. Tungsten is also used in great demand as a special hardening agent in the segment like armaments, steels, electronic, lighting and chemical industries.

The modern technology has a wide range of applicability for the unique metal tungsten. The distinct combination of properties of the metal such as highest melting point over all other metals, great density as well as low reactivity or toxicity are unbelievable and could not be found in any other single metal.

The following are some major use of tungsten in different industrial sectors:

A global consumption 61% of tungsten has been observed in the form of Cemented carbides which is regarded as the major use for tungsten. This is a ceramic which offers extreme toughness and hardness. The Cemented tungsten carbide (WC) is well suited in the creation of a variety of machine tools like cutting tools, wear parts and drill bits. The most recent and advanced application of Cemented tungsten carbide are the segments like the automotive, aerospace & defence, the oil & mineral exploration along with the construction sector.

The other huge usage area of the unique metal is intended foe steels and super alloys. It contributes near about a 20% of share in 2011. A proportional mixture of tungsten in a few sorts of steels enhances their hardness, durability and corrosion resistance ability. Steels made from this type of material are useful for the purpose of making cutting or drilling tools. The tungsten-containing super alloy’s application in the area of aerospace industry and for making blades for jet engines is outstanding.

The application of tungsten in mill products in the form of metal use has only a share of merely 11% as compared to the global consumption. The tungsten material that we use in our day to day life comes under this group. The filament in light bulbs, the ammunition and armour, application in automotive and aerospace industry, the furnace elements, in jewellery, in electronics, medical, wide nuclear applications, the sports equipment and welding electrodes are examples of application of tungsten in mill products.

Characteristics of Advanced Tungsten Bullets

Details: Category: Tungsten Information; Published on Wednesday, 10 September 2014 15:49; Written by jwy; Hits: 1975

When tungsten is made into an alloy, it becomes a suitable material for diverse ammunitions. These range from large to small caliber. In the manufacture of tungsten bullets, the desired quality is achieved through process mastery, strict inspection and innovation. The development of high quality materials is crucial to achieve optimal results.

MRX bullets are entirely covered by copper on the outside while their interior or core is made of dense tungsten. The high density of tungsten makes the bullets shorter than TTSX bullets. These bullets are ideal for bringing down large game as they penetrate deep into heavy tissue and bone. The bullets have streamlined polymer tips that are effective for shooting at flat long range trajectory. The tips also enhance bullet expansion during long range shots.

MRX bullets expand into four copper petals upon impact. This doubles the initial diameter of bullets, which consequently maximize the damage to tissue and bone. These bullets are effective for both long- and short-range shooting. The multiple rings that are embedded at their base reduce fouling while at the same time increasing accuracy.

The fact that these bullets contain absolutely no lead means that they are not toxic to the environment. They are available in different calibers and weights. Their weight varies between 130-150 grams while they have a diameter of .277 inches for the 7 mm caliber.

Tungsten bullets have been refined to produce the most lethal munitions technology. Compressed Ny-Trillium bullets, made from a tungsten powder/flake compound, have composite fragments that dislodge upon impact. It leaves an exit wound channel of immense proportions. These bullets have an expansive fragmentation characteristic that transfers the bullet’s energy much faster than the conventional hollow-points. The bullet is designed to expend maximum force into soft targets.

These advanced bullets have minimal ricochet characteristics and reduced occurrences of over-penetration. By containing the AFR bullet’s energy to its target including the bullet that is fragmented, over penetration is reduced. Because the bullets razor sharp fragments are not dislodged from traditional rounds, there is minimal risk to the operating personnel.

Upon hitting their target, AFR bullets disintegrate. This happens especially if the targets are hard like aircrafts and walls. However, upon impact with organic targets, they exhibit awesome stopping power. This type of ammunition is renowned for its special operational ability in anti-terrorism within aircrafts.

Tungsten bullets also make an excellent choice for home security in urban settings. Their safety is further elevated because of their reduced ricochet characteristics. If a bullet misses its target, there is reduced likelihood that it will penetrate multiple walls to injure someone sleeping. Personnel can take shots at rabid dogs without worrying that missed targets would cause bullets to ricochet and hit unintended targets.

Tungsten bullets have been designed into smart munitions. The rate of energy transfer to a hollow target more than doubles. The energy transfer rate quadruples when compared to conventional ball rounds. When they hit brittle targets, they disintegrate quickly minimizing the rate at which they penetrate or ricochet. They fragment at slower rates when the targets are soft. This means that more fragments lodge into the target leaving dozens of wound channels. The shock cavity created can have a diameter that exceeds seven inches.

Tungsten and Tungsten Carbide: What You Should Know About Them

Details: Category: Tungsten Information; Published on Wednesday, 10 September 2014 15:08; Written by jwy; Hits: 634

Tungsten and tungsten carbide have become increasingly popular options for jewelry, especially when it comes to rings. Let’s take a look at the characteristics of these two materials, and see what you should know about them when shopping for jewelry.

What Is Tungsten?

Tungsten is a metal that is extremely hard and melts at a very high temperature. It is also very dense, and the jewelry made of it feels surprisingly heavy.

Because of its durability, tungsten is a preferred material for buyers looking for jewelry that will last a very long time. However, the physical properties that make this metal so robust are also the reason jewelers find tungsten relatively hard to work with.

What Is Tungsten Carbide?

When tungsten is mixed with carbon, the resulting compound is called tungsten carbide. This material is even more durable than tungsten. The tungsten carbide used in jewelry making is usually mixed with a small amount of nickel.

Not only is tungsten carbide harder than tungsten, but it is also even tougher to fashion into a ring or another jewelry piece.

What You Should Know About Tungsten Carbide

Let’s look at the most important characteristics of tungsten carbide that you should be aware of when shopping:

Hypoallergenic: Tungsten carbide doesn’t cause allergic reactions when worn. Although the tungsten carbide used in jewelry usually does contain some nickel, this metal usually constitutes a small part of the final mixture. That’s why you shouldn’t worry about skin irritation if you are allergic to nickel and plan on wearing tungsten carbide jewelry.

Do make sure, however, that the vendor guarantees that the tungsten carbide jewelry offered is hypoallergenic. Different manufacturers have different standards for what their products contain, so it never hurts to check.

No scratches: One of the biggest selling points of tungsten carbide is that it is scratch resistant. It is very hard to make a dent or nick in a tungsten carbide ring under normal circumstances.

Tungsten carbide’s extreme durability means that if you have jewelry made of this material, it will stay polished for very long and won’t lose its luster with time, unlike gold or silver. Many companies selling tungsten carbide jewelry guarantee that their products won’t scratch and offer to replace them if you notice any scratches.

Cannot be resized: Tungsten carbide’s durability comes at a price: Rings made of this material cannot be resized. That’s why you should choose your size carefully to make sure your new ring is not too snug or loose. If, however, you finger size changes with time, you may be able to exchange your tungsten carbide ring for another of a different size: Some vendors offer such an option, so make sure to check when shopping.

Tungsten Carbide vs. Tungsten

People often use the terms tungsten and tungsten carbide interchangeably. However, there are differences in the properties of these two materials.

First, tungsten scratches more easily than tungsten carbide. Rings made only of tungsten are not really scratch resistant, so you shouldn’t expect them to stay as shiny as the ones made of tungsten carbide.

Second, tungsten jewelry often contains cobalt, whereas pieces made of tungsten carbide are usually mixed with nickel. The problem is that when cobalt comes in contact with your skin, the metal can cause irritation. Furthermore, cobalt can also oxidize and cause your tungsten jewelry to change in color.
