The gold-plated divided into two categories, one was homogeneous materials gilded, and the other is a heterogeneous material gold-plated. Other gilt plating characteristic points are mainly two categories: on the gold-plated metal parts and non-metallic gold-plated. The gold-plated quality of the pros and cons depending on the thickness of the gold layer how many shiny bright dark subjects. The gold-plated quality of the pros and cons of course also are closely related with gold-plated products , here we have to be recommended is a tungsten alloy gold plated product, especially our tungsten alloy golden eggs,it is more valuable than any other gold-plated products.

Tungsten alloy is an environmentally friendly, durable and a hardness material, the most important is its density, close to the density of gold (19.3g/cm3). These advantages of the tungsten alloy makes tungsten alloy gold-plated products enjoy certain advantages, is the best alternative of the expensive metal gold or platinum. The main products include: tungsten alloy golden bars, tungsten alloy golden rods, tungsten alloy golden coins, tungsten alloy golden eggs and so on.

Tungsten is the only lower value metal that has a specific density close enough to gold to fabricate passable counterfeit pieces of the same size and weight as genuine Pictures of tungsten alloy scan gold coins and ingots. Over the years, there have been a few isolated reports of smaller tungsten fake gold coin found to have been drilled to remove some of the gold which was replaced with tungsten. However, tungsten scan gold coin is far more profitable to fabricate larger original bars of tungsten that are then scanning gold.

Because the existence of counterfeit tungsten scan gold coin could have such a huge impact on the financial markets, there is a huge potential for deception and misinformation to be passed around. Be very careful about automatically believing any story you may hear. For your own protection, tungsten scan gold coin would be better to take physical possession of the smaller sizes of tungsten alloy scan gold coins and now, and know that what you own genuine solid tungsten scan gold coin.

Various different metals and alloys are used to create tungsten alloy fake gold brick, depending on the reason for, and nature of, the particular fake.

The alloy we see most frequently used for tungsten alloy fake gold brick is substandard gold, for example it sovereigns are made in the middle east and marked 21ct (but in Arabic), and we believe these are usually approximately 21ct, as opposed to 22ct gold. We also see tungsten fake gold brick sovereigns which appear to be around 18 to 20 ct gold, as well as some made of copper or bronze.

Just before we added this paragraph, we noticed a Wikipedia page about investment gold stating that lead is commonly used to make tungsten alloy fake gold brick. We cannot remember when we last saw a lead counterfeit of a gold brick, it is quite an infrequent occurrence. Lead would be too soft, feel wrong, and sound wrong. It would therefore be a very easily detectable fake, and probably not worth the effort of forger setting up any serious volume production.

Platinum has been used in the past!

We also see reports that tungsten can or are used to imitate gold brick, which is tungsten alloy fake gold brick. We have never yet seen tungsten fake, and consider it unlikely as tungsten must be quite difficult to work.

A top-of-the-line tungsten alloy fake gold rod should match the color, surface hardness, density, chemical, and nuclear properties of gold perfectly.

 To do this, you could start with a tungsten slug about 1/8-inch smaller in each dimension than the tungste fake gold rod you want, then cast a 1/16-inch layer of real pure gold all around tungsten fake gold rod.

This is would feel right in the hand, it would have a dead ring when knocked as gold should, the product would test right chemically, it would weigh exactly the right amount, and though I don't know this for sure, I think tungsten alloy fake gold rod would also pass an x-ray fluorescence scan, the 1/16" layer of pure gold being enough to stop the x-rays from reaching any tungsten. You'd pretty much have to drill it to find out it is fake.

Detecting a high-quality tungsten alloy fake gold bar would be extremely difficult. It would likely require significant and material alterations to the bar being tested and this would negatively affect the marketability if its hallmark veracity were vindicated. Some applications require the tungsten to be fake gold. The main reasons for tungsten fake gold bar are to protect the wire from corrosion or to solder it to other metals.

Besides, tungsten alloy products could also made as tungsten alloy fake gold bar which posses a better electric conductivity, and contribute greatly to the world industry development. Also tungsten fake gold saves the energy and poses no pollution threat to the environment and thus to achieve a sustainable development.

The conventional material of medical shielding is lead, atomic number of lead is 82, lead has good energy absorption characteristics, and it is an ideal material for shielding high-energy ionizing radiation. Looking from the particle absorption characteristics, and the lead has good absorption capacity to ionizing radiation which energy is higher 88.0keV and between 13.0keV and 40keV, but  for energy between 40keV to 88.0keV, there is a weak absorption zone.

Tungsten alloy shield is a new shield, and in the case of the same thickness as the lead shield, the effect of tungsten alloy shielding effect is better. And tungsten alloy shield is environmentally friendly, harmless to humans and nature, but lead is toxic, and the source of pollution, so tungsten alloy shield gradually replace lead as the most popular shield.

Principles of selecting the shielding material for shielding box are:

1. if the external magnetic interference is too high, the attenuation shield will be reduced. This is because when the external magnetic field is too high, the magnetic material will be close to magnetic saturation.

2. In the usual case, using the thickness metallic material to produce the shield case is not realistic, because of its high cost.

3. To make the maximum attenuation of the external magnetic field, it is need to use a high permeability (μ) of the material.

4. The magnetic shield effect is the material thickness of the cover shield diameter (at the time of its diagonal rectangular shield) the ratio (t / D) function of shielding.

Based on the above principles of selection, high density tungsten alloy shielding box is the best choice for shielding materials.

Shielding effect of the shielding case is measured by magnetic field intensity attenuation degree of device or component after shielding. After shielding, the magnetic field intensity attenuation rate is the functions of materials’ permeability, thickness and size of the shield function. High magnetic permeability material’s price is higher than the low magnetic permeability material, but if the shielding effect of the single layer of high magnetic permeability material and a multilayer material of low magnetic permeability are the same, then you could choose the thin material of high magnetic permeability, which will be more economical. Tungsten alloy shielding box, lead shielding box are widely used, but the effect of tungsten alloy shielding case is better than lead shielding case, although the thickness of tungsten alloy shielding case is thinner than lead shielding case.

The Materials for shield includes high density tungsten alloy, lead, iron, etc, depending on the different field and application to select a different shield material.

If the shield has budget control, then you could choose lead as the material of the shield, but if the shield is the point of application which needs limited space, so you need to choose tungsten alloy shield which is thin, and has good shielding performance. For very low frequency electromagnetic field changes (such as frequency 50Hz), you have to use a ferromagnetic material to shield, like shielded power transformer, you can choose iron to shield which has good magnetic permeability.

As can be seen from the chart, although the thickness ratio of the tungsten shield is smaller than lead shielding, the attenuation multiples of tungsten shield is higher, so we can obtain that tungsten shield is better.
