Characteristics of Tungsten Carbide

Tungsten carbide's good performance at temperatures up to 800 degree Fahrenheit make it a good choice in high temperature applications. It has good corrosive resistance in many environments. Tungsten carbide has a very low rate of thermal expansion, at 2 microinches per inch per degree Fahrenheit . Steel is 6.4 and aluminum is 12 microinches per inch per degree Fahrenheit.
 
One of the very important features of this material is that it is electrically conductive, with a resistivity of two micro ohms per centimeter. This conductivity sets it apart from other hard stiff materials, such as ceramics and sapphire, because it allows it to be machined into complex forms by the Electrical Discharge Machining process. Cemented Tungsten Carbide can be ground and lapped using diamond grit. The material is slightly magnetic. Small diameter balls can be picked up with a magnet. Cemented
 
Tungsten Carbide is very heavy, with a density of .54 pounds per cubic inch or 15 grams per cubic centimeter.
Tungsten cemented carbide stud is used to brush off corrosion on steel parts. Tungsten carbide use is cheap and affordable to many industry standard operations and is therefore the favored option by made tungsten carbide suppliers.

Tungsten Alloy Vial Shields Introduction

Vials shields manufactured from tungsten alloy provide an excellent solution to reduce the radiation dose to nuclear medical staff, protecting them from potential harm.

For safety reasons, in nuclear medicine, vials of radiopharmaceuticals are held in tungsten shields while the dose is drawn up into a syringe ready for treatment. The tungsten alloy vial shields reduce the finger dose received by medical staff, preventing exposure to harmful levels of radiation. Since tungsten alloy is very dense, some 60% more so than lead, the vial shields can be made more compact, making them easier to handle.In addition Wolfmet is far more durable than lead as it is a harder metal, which resists

surface chips and dents which can harbour bacteria. This resilient surface, in turn, makes it easier to clean and sterilise Wolfmet shields. Wolfmet is non-toxic so requires no painting or coating, eliminating the risk of paint chips which could compromise cleanliness.

There are many benefits of using tungsten alloy for vial shields ,such as High radiation attenuation; good shielding capability,Thinner and often lighter than equivalent lead shields,Easy to sterilise and keep clean,Non-toxic,Easily machined with conventional tools,Hard and durable – no need for steel or plastic coating,ect.

Tungsten Bell Fishing Sinkers

Tungsten bell fishing sinkers also called bass casting resemble a rain-drop or bell shape with a loop or an eye at their tapered top. Line can be passed through or tied directly to the eye. The eye is often made of brass, and some feature snaps, allowing anglers to clip-on or remove sinkers from the line without retying.

Tungsten bell fishing sinkers are favored by shore anglers as they can cast well in the wind. What is more, the rounded profile of the sinkers prevents snagging. Bell sinkers are often used on a three-way rig for boat anglers. The rig consists of a three-way swivel with one eye for the main line is designed to make baits deep without needing any extra equipment, like downriggers. The rig is effective when bounced along the bottom or lowered to a desired depth and trolled in open water.

Tungsten bell fishing sinkers are often made of lead or lead before, but they turn out to be environment hazard and non-corrosion resistance. Tungsten with the properties of good corrosion resistance and environment friendly becomes more and more popular for bell fishing sinkers’ materials.

The Advantages of Tungsten Alloy Shielding

tungsten alloy is used as a shield against gamma and x-ray radiation or as a collimator to focus radiation beams onto a target.

For many years ,tungsten heavy alloy has been the first choice for engineers requiring radiation shields or collimators to focus radiation beams. One key reason for this is tungsten alloy very high density; in fact it is more than 60% denser than lead, providing superior attenuation characteristics for x-ray and gamma radiation.

As well as the superior attenuation, tungsten alloy’s density also gives designers a significant advantage. It allows them to reduce the thickness of their shields and collimators whilst still providing the same protection as lead which is ideal for applications where space is restricted.

The Applications of Tungsten Alloys in Protecting Data Logging Instrumentation

With the development of science and technology,tungsten alloys has become an essential material for a wide variety of applications including balance weights, radiation protection, vibration absorbers, heat transfer and drilling bars. It has the highest melting point of any metal and its high density is equaled only by gold, platinum, and a few other rare and expensive metals.

The radiation shielding properties of tungsten alloy materials are excellent for use in fabricating products to enclose data logging instrumentation and isotopes, essential to locating oil and gas deposits. By shielding the instrumentation and personnel from radiation it dramatically improves the performance of the data logging.tungsten alloy products enhance real-time data logging while optimizing the drilling performance, improve rates of drilling stability and reduce the cost and time of searching for these vital resources. In addition, tungsten alloy products shield the gamma camera and sensors from the grueling work of drilling through the earth’s layers.
