3D Printing Pure Tungsten Parts in the Medical Industry 219

Tungsten, also known as Wolfram, is a rare metal known for its highest melting point of all elements. In addition to excellent temperature resistance, the material also has strong abrasion resistance and chemical resistance. These good properties make it an ideal material for components that operate at extreme temperatures. Pure tungsten does not have the hardness of composite materials, but its excellent heat resistance and radiation shielding properties are very useful in the nuclear and medical industries. The medical industry…

What Is the Best Material for X-ray Collimation – Tungsten Metal or Tungsten Alloy? 194

A collimator is a device used to transform the divergent light or other radiation from a point light source into a parallel beam, and also is an absorber device used to limit X-rays, gamma rays, or nuclear particle beams to the size and angular spread required for a specific application. Normally, special measurements in spectroscopy and geometric and physical optics require this kind of light collimation. For reasons of patient dose and image quality, X-ray collimation for radiography and fluoroscopy…

What Do You Know About the Disadvantages of TZM Plate or Sheet? 309

TZM alloy is an attractive molybdenum-based alloy (0.4-0.54% Ti, 0.06-0.12 %Zr, 0.01-0.04% C, balance Mo) utilized in industries with high strength, high temperature and vacuum requirements, including aerospace, electronics and heat treatment. TZM alloy plate can perfectly server these areas when the working temperature ranges from 700 ℃ to 1400 ℃。 Compared with pure molybdenum plate, TZM plate has a more stable crystal structure and a higher recrystallization temperature. This is due to the small amount of zirconium and titanium…

Why Use Thorium Tungsten Wires as Ion Source? 214

Many analytical and medical devices are using thorium tungsten wires as ion source. Why use thorium tungsten materials? What about tungsten or neodymium tungsten materials? Electrons are made available from a cathode in the source, which in most cases will use thermionic emission, i.e., heating the material so that electrons gain some energy and are able to escape the work ding of the cathode material (the energy required per electron to leave the material). To lower work ding, manufacturers would…
