Tungsten Alloy Collimator for Radiotherapy

Details: Category: Tungsten Information; Published on Thursday, 11 July 2013 10:02; Hits: 2064

Tungsten alloy collimator is widely used for radiotherapy. In China, radiotherapy was begun in 1930’s. Radium Hospital (Fudan University Shanghai Cancer Center), build in 1931 and Peking Union Medical College Hospital (having 200mg radium needle, a 200kV X-ray therapy apparatus and a 120kV X-ray therapy apparatus), build in 1932, were the first hospitals launching the earliest radiotherapy in China. At the end of 1950’s, China imported the first ⁶⁰Co therapy apparatus, high energy ray device. China imported the first betatron in 1968 and the first liner accelerator in 1975. In recent years, radiotherapy has developed unprecedentedly. All of new radiotherapy techniques are developed including three-dimensional stereotactic radiotherapy (gamma knife, X-ray knife, conformal therapy and intensity modulated radiotherapy). Researches on tumor radio physics and radio biology also achieve fruitful results. In recent years, hospitals adding radiotherapy in every province, city, prefecture-level city, county-level city even small towns are more and more. Radiotherapy equipments are more and more advanced.

Tungsten alloy collimator is used for guiding X-ray to protect patients and doctors from radiation. Density of tungsten alloy is higher than lead by 60%. The high density allows a reduction in physical sizes of collimator without compromising effectiveness of shielding characteristics. Otherwise, tungsten alloy has the advantage of non-toxicity. So tungsten alloy is more suitable for collimator, compared with lead.

Strong Wind Resistance of Tungsten Fishing Weight

Details: Category: Tungsten Information; Published on Thursday, 11 July 2013 09:34; Hits: 1990

Tungsten fishing weight is an ideal, environment-friendly alternative to lead weight, which are toxic and increasingly being labeled an environmental hazard.

As the high density of tungsten, the tungsten fishing weight 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.

Metal Injection Molding for Tungsten Alloy

Details: Category: Tungsten Information; Published on Thursday, 11 July 2013 09:41; Hits: 2191

Metal Injection Molding (MIM) is a growth technology for manufacturing complex-shaped,high-volume metal or alloy parts. Metal Injection Molding (MIM) parts can be produced from ferrous and non-ferrous metals and alloys.

The advantages of Metal Injection Molding (MIM)
Density: Typically 95-98% of wrought material. Mechanical Properties - Comparable to wrought alloys of similar composition. Complexity - Geometries comparable to plastic injection molding. Surface Finish: As processed, 32 ram or better. Corrosion Resistance - Comparable to wrought alloys of similar composition. Alloy Selection - Many ferrous, nickel-based and copper-based alloys available.

Advantages of Tungsten Alloy Fishing Weights

Details: Category: Tungsten Information; Published on Thursday, 11 July 2013 09:29; Hits: 1886

Tungsten alloy fishing weight has many advantages such as high density with small volume, good corrosion resistance, perfect hardness,etc.

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