Tungsten Alloy Radiation Material

In physics, radiation is a process in which energetic particles or energy or waves travel through a medium or space. There are two distinct types of radiation; ionizing and non-ionizing. The word radiation is commonly used in reference to ionizing radiation only (i.e., having sufficient energy to ionize an atom), but it may also refer to non-ionizing radiation. The energy radiates from its source. This geometry naturally leads to a system of measurements and physical units that are equally applicable to all types of radiation. Both ionizing and non-ionizing radiation can be harmful to organisms and can result in changes to the natural environment. 

Tungsten is used in many radiation shielding applications including industrial, nuclear and medical. Because of its high density and high atomic number, is an effective construction material for shielding from gamma rays and x-rays. Lead and boron carbide can shield radiation too, But can’t performance as good as tungsten alloy

Tungsten Titanium Wedding Rings


Men's Black Titanium Tungsten Wedding Rings
Titanium Jewelry is one of the fastest growing jewelry industries nowadays. The fact that Titanium is such a hard and durable alloy makes men's black titanium wedding rings perfect for symbolizing the eternity of love.


Unique Men's Titanium Bracelets
Combination of Titanium, gold, silver and diamonds offers unique and stylish designs. Our gold and silver inlay collections are the most popular picks for men's titanium bracelets.

Tungsten Carbide Ring
Tungsten carbide is one of the new metals from which jewelry designers have begun to craft tungsten carbide rings, offering a wide variety of styles and designs that fit every taste and budget.

Cobalt chrome wedding rings
Cobalt superalloy has long been used in building jet aircraft engines due to its strength and heat resistance. The technology is now applied to create durable and elegant fashion jewelry. Cobalt chrome alloy offers premium white gold color that is long lasting and does not tarnish. Cobalt rings are harder than steel, yet much lighter than steel.

Stainless Steel Jewelry
It is the image of these times, when the metal that has become what we call stainless steel today, was used to forge one of the ultimate symbols of manhood, the sword. The same proud craftsmanship is brought to bear in the stainless steel jewelry for men.

Shapes of Tungsten Alloy Fishing Jigs

Tungsten weights are an ideal, environment-friendly alternative to lead weights, which are toxic and increasingly being labeled an environmental hazard. Tungsten weights are harder than steel and extremely dense, tungsten being on average 30 percent smaller than its lead counterpart. Tungsten weights are smaller than conventional weights, create twice the sound of lead weights and maintain their shape for longer. Tungsten is also used in the production of other fishing applications, such as tungsten-carbide line cutters and tungsten powder coating for fishing lines.



A fishing sinker or plummet is a weight used to force a lure or bait to increase its rate of sink, anchoring ability, and/or casting distance. Fishing sinkers may be as small as 1/32 of an ounce for applications in shallow water, even smaller for fly fishing applications, or as large as several pounds or considerably more for deep sea fishing. They are formed into nearly innumerable shapes for diverse fishing applications. Environmental concerns surround the usage of most fishing sinker materials.

A jig is a type of fishing lure that usually consisting of a lead sinker with a hook molded into it and usually covered by a soft body to attract fish. However, recently, tungsten alloy fishing weights ( fishing sinkers) is becoming more and more popular among angles because it has the features of high density, small volume, and environmental friendly, and has been taking place of the lead sinker. Jigs are intended to create a jerky, vertical motion, as opposed to spinnerbaits which move through the water horizontally. The jig is very versatile and can be used in both salt water as well as fresh water. Many species are attracted to the lure which has made it popular amongst anglers for years.
The fishing sinker/ weight is made by rare metal - Tungsten, it is an ideal substitute of the lead fishing sinker. It's strong adhesive, semi-solid state, soft for a long term.
Tungsten Heavy Alloys concentrate maximum weight in the smallest possible space. They are more often to be used as counterweight in sporting field, such as tungsten alloy fishing sinkers, golf weights, etc.

Advantages of tungsten  
1. Heat resistance
The melting point of tungsten is 3380 degrees Celsius .
And the melting point of iron is only about 1500 degrees Celsius
2. Hard
When tungsten combines with carbon, t will become very hard. The hardness is close to the diamond.
3. High density
The density of tungsten is almost the same with gold.
We can offer tungsten alloy fishing sinkers/weights, tungsten beads, tungsten jig at various shape, such as shape of bullet, drop, tube, semi-drop and cylinder. Besides, we can manufacture fishing sinkers/weights according to your drawings.

What's tungsten alloy fishing sinkers

Tungsten Alloy Fishing Sinkers are large proportion (> 18g/cc), small size. They are against strong wind, light into the water, sinking fast, and are the best alternative to lead sinkers. The Fishing Sinkers are best-selling in Europe, the United States and other developed countries.
Advantages of
tungsten alloy fishing weights/sinkers

1. Small volume

High density make tungsten alloy fishing sinkers/weights smaller than the conventional lead fishing weights. It will be hung up far less with a tungsten sinker than with a lead sinker because of its smaller size.

2. HardIt's harder than lead fishing weight. It will not be stuck in the jowl of the fish. So the shape will be maintained longer.

3. Strong wind resistanceAs the high density of tungsten, the tungsten alloy fishing sinker makes your fishing easier. It is extremely sensitive and can actually help you “feel” what the bottom is made of and what your bait is bumping into, such as brush, rocks, mud, etc.Tungsten fishing weights/eyes are an ideal, environment-friendly alternative to lead weights, which are toxic and increasingly being labeled an environmental hazard.The main specifications are: drop type, bullet type, Circular tube type, ball type. Please kindly refer to the following:

Gold-Plated Tungsten Bar Found In The UK

Recently, the German television station ProSieben ran a news story covering W. C. Heraeus in Hanau, Germany, the world’s largest privately owned refinery. In the story, Wilfried Hörner, the head of the gold foundry, shows a 500 gram bar (16.0755 troy ounces) received from an unidentified bank. The bar had the right physical dimensions to be an authentic tungsten alloy fake gold bar, but one of the Heraeus employees suspected something funny. After the bar was cut in half, you can see that the inside is tungsten, with only a coating of gold on the outside.


Let’s consider the run-up to Rome’s hyperinflation. I think this comment from jaysromanhistory.com “Good Money, Bad Money, and Runaway Inflation” resonates with what’s happening in the US today:

“Severus Alexander (AD 222-235) tried to reform by going back to the denarius but, once started, this path of runaway inflation and financial irresponsibility on the part of the imperial government proved impossible to control.”
It also seems that the hyperinflation was preceded by some kind of banking crisis, which is an interesting parallel. From “Demise and Fall of the Augustan Monetary System” by Koenraad Verboven:

Papyri show it was common for private individuals to deposit money at a bank and to make and accept payments through bankers.Bankers in the west disappear from view around the middle of the 3rd c… A famous papyrus from Oxyrhynchus from 260 CE shows exchange bankers closing in order to avoid having to change the ‘imperial money’. The strategos ordered the exchange bankers to reopen and accept all genuine coins and warned businessmen to do the same. In 266 CE we find for the first time transactions being expressed in ‘ptolemaeic’ or ‘old silver’ as opposed to ‘new silver’.


The chart shows how inflation remained relatively subdued until a tipping point was reached in the late- 260s A.D Monetary systems can absorb substantial abuse before there is a dramatic impact on the price level. For example, the debasement of the coinage was already accelerating in the early part of the third century A.D., before plunging in the latter part. Indeed, the chart below (apologies for the quality) only shows the trend up to 253 AD. By around 290 AD, the coins were only dipped in silver to give them a coating (<0.5%):
