Tungsten Copper Foil (WCu Foil) Can Withstand Extreme Temperatures 196

Tungsten-copper alloys are pseudo-alloys of copper and the refractory metal tungsten. Since copper and tungsten are immiscible, the material consists of different particles of one metal dispersed in a matrix of another metal. As a result, the microstructure is a metal matrix composite rather than a true alloy. It combines the properties of two metals to form a material that is heat, ablation resistant, highly thermally and electrically conductive, and easy to process. It is also resistant to arc corrosion,…

Tungsten Filaments and Crucibles for Microprobe and Electron Beam Systems 206

Electron microscopes generate images by bombarding samples with electrons and then converting the results of this interaction into visual images. In order to form an image, the generated electrons need to be tightly controlled. Electron beams come from filaments made of various materials. The most common is the tungsten hairpin gun, which is widely used in scanning electron microscopes, transmission electron microscopes, and microprobe systems. This filament is a tungsten ring that acts as a cathode. Apply voltage to the…

Will Russia-Ukraine War Make Yttrium Tungsten Electrode (WY20) Price Increase? 225

Yttrium is a lanthanide metal found in most rare earth minerals, especially yttrium tantalite. It can be used as the yttrium phosphor to produce the red color on television screens and monitors and used as a superconductor and as a component of X-ray filters and superalloys. When added to tungsten as a rare earth element, it can be used as a welding electrode. Among the non-consumable electrodes, the yttrium tungsten electrode is the most consistent, so it is often used…

TZM Plate or TZM Sheet for Structural Furnace Components 276

Metal sheet/plate is a thin sheet/plate made from different materials of tungsten, tungsten alloys, molybdenum and molybdenum alloys. The sheet could be formed by hot rolling procedures and is polished further with different finishes depending on the applications. TZM has several valuable properties such as high strength, creep resistance, hardness and low vapor pressure in high temperature environments. Sheets/plates made of TZM alloy thus have low expansion coefficient, excellent heat and corrosion resistance and good machinability. Compared with pure molybdenum…
