Physical properties of tungsten electrodes
Tungsten electrode is a commonly used metal electrode material with many excellent physical properties. The following are some of the main physical properties of tungsten electrodes. Density: Tungsten has a very high density of approximately 19.3 grams per cubic centimeter, making it one of the densest metals in nature. Melting point: Tungsten has a very high melting point, approximately 3422 degrees Celsius (6192 degrees Fahrenheit). This allows tungsten electrodes to maintain stability and durability in high temperature environments. Thermal Conductivity: Tungsten has good thermal conductivity, approximately 174 W/m·Kelvin. This allows the tungsten electrode to conduct heat efficiently while providing good thermal stability for high temperature applications. Linear expansion coefficient: The linear expansion coefficient of tungsten is about 4.5 x 10^(-6) K^(-1), which means that the dimensional change of the tungsten electrode when the temperature changes is relatively small. Electrical Conductivity: Tungsten has a relatively high electrical conductivity, around 18-30 MS/m (megasiemens/meter). This allows tungsten electrodes to provide good electrical conductivity properties in electronic devices and power applications. Mechanical Properties: Tungsten has excellent mechanical properties, including high strength, excellent corrosion resistance and oxidation resistance. This allows the...

Physical properties of niobium
Niobium is a gray-white metal with a melting point of 2468°C, a boiling point of 4742°C, and a density of 8.57g/cm3. Niobium is a lustrous gray metal that is paramagnetic. High-purity niobium metal is highly ductile but hardens as the impurity content increases. Niobium exhibits superconducting properties at low temperatures. Under standard atmospheric pressure, the superconducting critical transition temperature T of niobium is 9.25K, which is the highest among all metals with superconducting properties. Its magnetic penetration depth is also the highest of all elements. Niobium is one of three elemental Type II superconductors, the others being vanadium and technetium. The purity of niobium metal greatly affects its superconducting properties. Niobium has a very low capture cross section for thermal neutrons, so it is quite useful in the nuclear industry.

Thermophysical properties of molybdenum rods
1. High melting point The melting point of molybdenum rod is 2610°C, which is one of the highest melting points of all metals. This allows the molybdenum rod to maintain stability and strength at extremely high temperatures and therefore has a wide range of applications in high temperature environments. 2. Low thermal expansion coefficient The linear expansion coefficient of molybdenum rods is very small and the thermal expansion coefficient is low, which allows the molybdenum rods to maintain the stability of their shape and size at high temperatures, which is of great significance to the manufacturing of high-temperature equipment and components. 3. Good thermal conductivity Since molybdenum has a relatively large thermal conductivity, molybdenum rods have good thermal conductivity and are suitable for the production of various high-temperature thermally conductive components and devices.
