Performance of screws made of pure tungsten material
The core advantages of pure tungsten material screws are extremely high density, high melting point, high hardness, and good electrical and thermal conductivity. However, pure tungsten itself is brittle and difficult to process, so it is usually necessary to control the specifications, tolerances, and assembly methods when making screws.Suitable application scenariosFasteners for high-temperature equipment such as vacuum furnaces, high-temperature furnaces, and si

Characteristics of 42 alloy
42 alloy usually refers to Alloy 42/4J42/FeNi42, which is an iron nickel constant expansion alloy with a nickel content of about 42%, corresponding to American standard UNS K94100 and ASTM F30. It is not a high-strength structural component material, nor is it a high corrosion resistant alloy. Its core advantage lies in its low and stable coefficient of thermal expansion, which can be well matched with glass, ceramics, silicon chips, and other materials.Typical Ap

Characteristics of niobium metal
Niobium is a rare silver gray refractory metal with a melting point of about 2468 ℃ and a density of about 8.57 g/cm ³. It is lighter than tungsten and tantalum, but has outstanding high temperature resistance. It is chemically stable at room temperature and has good corrosion resistance to most acid, alkali, and salt solutions. It is insoluble in aqua regia, but can be corroded by hydrofluoric acid and strong oxidizing media.Niobium has good plasticity and can be
