Applications of Tungsten Alloys Radiation Shielding

Details: Category: Tungsten Information; Published on Monday, 01 September 2014 17:48; Written by yewq; Hits: 531

Whether you need to protect sensitive electronic equipment or delicate human tissue, the energy-absorbing properties of Mi-Tech Metals’ tungsten alloys make them exceptional choices for radiation shielding applications, in both medical and industrial settings.

Tungsten alloys are used for radioactive source containers, gamma radiography, shields, and source holders for oil-well, logging, and industrial instrumentation. High-density alloys also serve as collimators and radiation shielding in cancer therapy, as well as syringe protection for radioactive injections. When you need to direct a specific amount of radiation to a targeted area, tungsten alloys provide the control you need. Mi-Tech Metals’ high-density alloys will continue to perform, even under extreme, high-heat conditions.

Compared to traditional radiation shielding materials, tungsten alloys provide excellent value. A high-density alloy can provide the same energy absorption as lead using 1/3 less material! Unlike lead, you’ll also reduce administration costs by eliminating the need to obtain special licensing—it’s not required.

Tungsten Split Shot Fishing Sinkers 1

Details: Category: Tungsten Information; Published on Monday, 01 September 2014 11:45; Written by Sherry; Hits: 555

Tungsten split shot fishing sinkers feature for a groove that runs the full length of the sinker are one of the most well-known and widely used sinkers. The groove holds the line once the sinker is impacted in place.Split shot fishing sinkers are often used with live-bait offerings. The combination of a split shot above a hook with a worm suspended below a bobber is appreciated by many experienced anglers because this perfect combination has caught thousands of fishes for them.

According to the shape of the tungsten split shot fishing sinkers, we can classify into the three types.

Removable tungsten split shot fishing sinkers

Removable tungsten split shot fishing sinkers feature for small handles on the opposite side of the opening, allowing you to squeeze the shot back off your line and allowing them to be removed and reused on your lines over and over again, which prolong the life.

Removable tungsten split shot fishing sinkers are made by a patented process which forms very soft lead into precise pieces, resulting in a controlled hinge that can be squeezed onto the line on by fingers, it means that you can interchange sinkers instantly with just a snap of your fingers, no tools or teeth are needed.

Introduction and Application of Ferro Tungsten

Details: Category: Tungsten Information; Published on Friday, 29 August 2014 09:37; Written by jwy; Hits: 530

Tungsten, a silver-gray metal, is mined from scheelite and wolframite and appears in nature in four major forms combined with calcium, iron or manganese. Most current mine production of tungsten is from vein/stockwork, skarn, porphyry and strata-bound deposits. Minor amounts are produced from pegmatite, breccia and placer deposits. It has a high melting point and density, good thermal and electrical conductivity, a low coefficient of expansion as well as exceptional strength at elevated temperatures. It is consumed predominantly as tungsten carbide in cutting and wear-resistant components as well as an alloying agent in steel making. Also, often as an alloy, it is used for lamp and lighting filaments and electrodes, electrical and electronic contact surfaces, heat and radiation shielding in high-temperature furnaces and X-ray equipment, and electrodes in certain welding methods. Some non-metallurgical applications of tungsten are as phosphorescent chemicals in pigments, X-ray screens, television picture tubes and fluorescent lighting. Tungsten is also used in armor-piercing ordnance and tank shielding. The name tungsten comes from the Norse word thungr-steinn, which means "heavy stone."

Ferro Tungstenh Improving the hot hardenability, abrasion resistance and impact strength of steel, used in production of high-speed tool steel, alloy tool steel, heat-resistant steel, spring steel and magnetic steel.

What is Tungsten and How Tungsten Used?

Details: Category: Tungsten Information; Published on Monday, 01 September 2014 11:08; Written by jwy; Hits: 539

Tungsten, also known as wolfram, is a chemical element with the chemical symbol W and atomic number 74. Tungsten is as known the heaviest materials except gold of the nature resources, for the density of tungsten is 19.25g•cm3(near r.t.). For the same reason, tungsten related products, alloys, other elements doped and carbides have the special characteristics as pure tungsten, then it always named heavy stone.

Tungsten is one of Nonferrous Metals, and also it is as molybdenum and rare earth which are Refractory Metals, in the modern industrial time, it is the most important Strategic Metals for IT industrial and military industrial.

How is tungsten used? Tungsten alloys are good conductors of electricity, and used primarily to increase the toughness and strength of steel. The most common tungsten product, cemented tungsten carbide, is used to make grinding wheels and cutting or forming tools. Tungsten powder is used as a lead replacement in bullets. However, firing of a tungsten/nylon bullet introduces tungsten and other projectile related metals into the environment.
