High purity tungsten is soft texture, the project is usually mixed with Ni, C and other elements to replace pure tungsten, tungsten alloy is heavy alloy, it inherits the characteristics of good tungsten, enhances its hardness, and maintains a good shape. The following table lists the attenuation coefficient of tungsten nickel and lead to different energy photons.

As can be seen from the graph, the attenuation of the different photon energy is 10 times, the thickness of the tungsten alloy is smaller than lead shielding.

Structural of lead is poor, and not resistant to high temperature. When lead used to manufacture container, screen activity, lead bricks, it is necessary to use the steel to make skeleton structure, otherwise, it will collapse of its own weight.

The atoms coefficient of tungsten is 74, which is one of natural high density elemental metal. Tungsten and lead production are applied to the shield member, but density of lead is smaller than tungsten (the density of lead is 11.34g/cm3, tungsten density 19.25g/cm3), shielding performance is worse than that of tungsten, besides, lead is toxic, it harms the environment and human health, so tungsten shield gradually replace lead shielding, the best choice of the shield.

As it can be seen from the following chart, the performance of tungsten shielding is much larger than the lead. As far as research, shielding properties of materials are closely linked with the density, the greater the density, the better the shielding properties of the material. From the above chart we can see that the density of tungsten is 1.5 times denser of lead, so shielding properties of tungsten is better. Moreover, lead is toxic and potentially mixing hazardous waste, it is harmful to the environment.

With the heavy density of 19.25g/cm3, similar to the density of real gold, tungsten alloy material is widely used as gold substitution for gold-plated tungsten alloy gift nowadays.

Gold, silver, or platinum, or more commonly zinc or nickel are used as alloys in most jewelry, however, if you choose tungsten golden jewelry as gold substitution, which could keep you away from the allergic of real gold, because tungsten golden jewelry and gold-plated tungsten jewelry are hypoallergenic. This means that you will no longer have to deal with rashes and discolored skin from wearing your tungsten golden jewelry.

There are many kind of tungsten golden jewelry such as gold-plated tungsten ring, gold-plated tungsten earring, gold-plated tungsten chain, gold-plated tungsten bangle, gold-plated tungsten bracelet, gold-plated tungsten pendant, etc. Of course, gold-plated tungsten jewelry and tungsten golden jewelry could be used as free golden sample for your testing.

1: The distance tungsten alloy fishing sinkers and hooks should be appropriate: fishing sinkers and hooks from the general to the city inch 1 inch or 1 is appropriate, when the target for the big fish, need to lengthen the distance between the fishing sinkers and hooks. Fishing sinkers and hooks in the distance, it will affect the success rate of fishing: when the distance is too long, floats reaction when fishing is slow, can not be timely closing line; When the distance is too short, easy to hit the fish head, so that is not hooked fish run away.

2: The size of the tungsten alloy fishing sinkers and severity, with fishing line hooks should be supporting. crude hook with crude falling and thick line; thin hook with thin fall. and thread.When carp fishing sinker beans can be slightly larger than the half-hearted.

3: tungsten alloy fishing sinker should be consistent with the water quality. In freshwater, tungsten alloy fishing sinker optional weight of 1/8 oz to 1/4 ounce, in deep water, tungsten alloy fishing sinker weight optional 3/8 ounces to 5/8 oz.

4: tungsten alloy fishing sinkers and supporting the use of bait. In deep sturdy  bait.

With the development of science and technology, more and more radiation in our lives, X-rays, gamma rays, α-rays, and β-rays. For people's health, shields and the materials are more and more paid attention. Tungsten alloy shield advantages are:

1. High density. Based on the research, the greater the density of the material, the better the shielding performance. The density of  tungsten is 2 times bigger than lead.

2. Environmental friendly. Tungsten alloy is environmentally friendly, but the original material, lead, is heavy metals pollution, which is great harm to the environment and the human body.

Gold-plated tungsten coin is manufactured in the form of golden coin, which is only for gift, present, handicraft, and never could be used for any illegal purpose. Gold-plated tungsten alloy coin is first made before golden-plating on it. It is also has the properties of high density and corrosion resistance. Therefore, the value would be remained for even it is just product.

Owing to durable, hardness, oxidization resistance, environmental-friendly and weak radioactive, and the most important advantages is that it is almost has the same weight as real gold, gold-plated tungsten coin has been the most reasonable material for commemorative coins, golden souvenir, birthday present, weeding anniversary present, etc. Even it could be used as a secret surprise for your VIP customer, the best friend, the most favorable teacher, etc.

Short positions easily lead ship capsized hull, cargo vessels required emptied after something carried high weight of ballast, and ship ballast high density tungsten alloy has now become the most popular ballast material, its main advantages are:

High density: As the density heavy alloy can reach 18.50g/cm3, which has a strong advantage in terms of weight purposes, and help to improve the sensitivity of ships and controllable.

Strong wear resistance and high tensile strength: high-density tungsten has a high tensile strength and good abrasion resistance, the role of the environment is not restricted.

Easy processing: cutting high density tungsten alloy is relatively easy to implement, this design specifications, complex size, high density tungsten alloy with the feasibility of providing ballast weight of the block.

Tungsten is an important part of the engine crankshaft, the rotation of the crankshaft of the engine is the power source is the power source of the mechanical system. In the course of their work will inevitably crank friction and damage, which makes tungsten alloy crankshaft how maintenance is very important.

Dirty oil or discontinuity spigot rod wear will increase the contact surface of the stud to the journal, if severe wear will reduce the efficiency of the combustion, the impact of the stroke length of the piston up and down, thereby reducing power output. When the existence of particles larger hard dangerous impurities, there are also scratch the surface of the journal. At the same time the crankshaft may also be due to lack of lubrication or oil is too thin, causing burns journal surface. Therefore regular maintenance tungsten alloy crankshaft, select the appropriate viscosity lubricants, lubricants and cleaning to avoid mixing of particulate matter in the oil, change the oil regularly, keeping the crankshaft clean.
