The Brief Introduction of Silver Tungsten Electrode

Silver tungsten electrode is also called silver tungsten rod or silver tungsten bar. Silver tungsten electrode is one kind of silver and tungsten alloy products.
 
Silver tungsten electrode can only be made by powder metallurgy and pressing method. Silver tungsten electrode has good hardness, high arc corrosion resistance and high fusion welding resistance.
 
Due to these excellent properties, silver tungsten electrode can be used as high temperature resistance material, microelectronics material. Silver tungsten electrode can also be applied in aerospace and aviation, metallurgy, machinery and sports equipment.

Tungsten Resources in China

We will learn about tungsten resources in China.
 
1. Tungsten production in China
China is the world's richest country which has tungsten resources and the world's largest producer and exporter of tungsten.
 
2. Tungsten resources in China
With the rapid development of tungsten production, China's tungsten resources reserves are reducing, especially the black tungsten resources.
 
3. China’s tungsten consumption and the consumption structure
Chinese domestic tungsten consumption generally is 10000 tons / year or so. Statistics show that, from 1980 to 1985, tungsten used to produce steel  accounted for 61% of total tungsten consumption and is the largest proportion; while tungsten used to produce hard alloy accounted for only 28% of total tungsten consumption. 1986-1990, tungsten used to produce steel dropped to 48%, and tungsten used to produce hard alloy rises to 40%. 1991-1995, with hard alloy production going high, tungsten used to produce hard alloy rises to 50% of total tungsten consumption.

Tungsten Bullet Fishing Sinkers

Tungsten bullet fishing sinkers also called corn sinkers follow the same premise as egg sinkers in that they are threaded onto the line, with the narrow point facing towards the rod.  The bullet-shape of these sinkers makes them ideal for gliding through weeds. These sliding sinkers can be used on a live bait rig to replace a walking sinker when used in weedy areas.  A weedless hook will also greatly enhance the effectiveness of this weed-rig.

Tungsten with the high density and environment protection is to be the ideal material for the tungsten bullet fishing sinkers. Lead, as the traditionally used material is gradually replaced by tungsten based because of it is toxic, and harmful to our environment.

The Introduction of MLC

A multileaf collimator (MLC) is a device made up of individual "leaves" of a high atomic numbered material, usually tungsten, that can move independently in and out of the path of a particle beam in order to block it.

MLCs are used on linear accelerators to provide conformal shaping of radiotherapy treatment beams. Specifically, conformal radiotherapy and Intensity Modulated Radiation Therapy (IMRT) can be delivered using MLC's.

The MLC has improved rapidly since its inception and the first use of leaves to shape structures in 1965  to modern day operation and use. MLC's are now widely used and have become an integral part of any radiotherapy department. MLC's were primarily used for conformal radiotherapy, and have allowed the cost effective implementation of conformal treatment with significant time saving, and also have been adapted for use for IMRT treatments. For conformal radiotherapy the MLC allows conformal shaping of the linear accelerator (LINAC) beam to match the borders of the target tumour. For intensity modulated treatments the leaves of a MLC can be moved across the field to create IMRT distributions (MLC's really provide a fluence modulation rather than intensity modulation).

The MLC is an important tool for radiation therapy dose delivery. It was originally used as a surrogate for alloy block field shaping and is now widely used for IMRT. As with any tool used in radiotherapy the MLC must undergo commissioning and quality assurance. Additional commissioning measurements are completed to model a MLC for treatment planning. Various MLC's are provided by different vendors and they all have unique design features as determined by specifications of design, and these differences are quite significant.

Tungsten Alloys In Nuclear Technology

Tungsten alloys are widely applied in nuclear technology.
 
Tungsten alloys are such kind of alloys which are mostly composed of tungsten and other elements, like niobium, copper, molybdenum and others. The density of tungsten alloys can reach 16 .5-19.0g/cm3. Tungsten alloys can also be called heavy alloys. Tungsten alloys have a series of advantages, like high proportion, high intensity, strong ray absorption ability, big thermal conductivity, small coefficient of  thermal expansion, excellent conductive properties, excellent weldability and workability.
 
Due to these excellent properties of tungsten alloys, tungsten alloys are widely applied in aerospace, aviation, military, oil drilling, electrical instrument, medical industry and other industries.
 
Tungsten alloys are used in nuclear technology, like tungsten alloys being used as radiation shielding container, geological survey container, tungsten alloy collimator, pipeline inspection ray shielding tungsten collimator, industrial radiography gamma ray shielding tungsten collimator and others.
 
Tungsten alloys can also be used as ray shielding materials in medical science. In addition, tungsten alloys are able to be applied in machinery, sports, mobile phones and other fields.
