Molybdenum wire standards and grades

Molybdenum wire features a high melting point, high strength and elastic modulus, a low coefficient of expansion, low vapor pressure, excellent electrical and thermal conductivity, and corrosion resistance. It is widely used in lighting, vacuum devices, machining, and spray coating applications. Molybdenum wire standards provide comprehensive regulations for its quality, specifications, production, and applications, representing the technological level of molybdenum wire production. China’s earliest molybdenum wire standard was SJ316-72, “Molybdenum Wire,” in 1972. Following improvements in molybdenum wire production technology, GB4182-84 “Molybdenum Wire” was released 12 years later, and T4182-1997 “Molybdenum Wire” was released 15 years later. The currently commonly used standard is GB/T4182-1997 “Molybdenum Wire.” US molybdenum wire standards are categorized into coarse and fine wires, defined by ASTM F 289 and ASTM B 289. ASTM F 289 was developed in 1954 and first published as ASTM B289-54 T. It was revised again two years later and re-established as ASTM F 289-56. Twenty-five years later, it was revised as ASTM F 289-81, and 15 years later, it was revised again and published as ASTM F 289-96. The current standard is ASTM F 289-96. ASTM B 387 was first published in 1962, with the original version being ASTM B687-62 T....

How to prevent cracks in tungsten crucibles?

In actual use, tungsten crucibles often face the risk of crack formation, which not only affects their service life, but also directly affects process stability and product quality. Therefore, how to effectively prevent the formation of cracks has become a key concern in the industry. First, material purity and quality control are fundamental to preventing crack formation. High-purity tungsten powder raw materials help reduce internal impurities and grain boundary defects, improving the overall density and uniformity of the crucible. Impurities can easily become stress concentration points for cracks, leading to crack initiation and propagation during high-temperature thermal cycling. Therefore, during the powder metallurgy production of crucibles, strict control of raw material purity and sintering processes to ensure a dense and porosity-free product are key steps in crack prevention. Second, optimizing processing techniques is crucial for crack prevention. Tungsten is inherently brittle and hard, easily subject to mechanical stress and microcracks during processing. Using CNC precision machining, optimal cutting parameters, and a multi-stage polishing process can significantly reduce surface defects and stress concentrations. Furthermore, smoothing the inner wall not only improves heat transfer efficiency but also reduces the risk of stress concentration and crack initiation points caused by surface roughness. Furthermore,...

What is Molybdenum Foil?

Like molybdenum plates, rods and wires, molybdenum foil is also a typical molybdenum product. It is a thin sheet composed of transition metal molybdenum (Mo) and rare earth elements. Its English name is Molybdenum foil. Its purity is usually greater than 99.95%, with a thickness of 0.025-0.09mm, a width of 30-100mm, and a length greater than 200mm. The surface conditions include alkaline pickling surface, annealing state and polished surface. In terms of physical and chemical properties, molybdenum foil is a silver-gray metal sheet with a metallic luster. It has a melting point of approximately 2620°C, a boiling point of approximately 5560°C, and a relative density of 10.2 g/cm³. It exhibits high hardness, low thermal expansion coefficient, high thermal conductivity, low resistivity, and excellent chemical stability and electrochemical properties. At room temperature and pressure, it does not react with air or water, but it slowly oxidizes under heating. In terms of production methods, the following steps are involved: Medium-particle molybdenum powder is used as the raw material, and cold isostatic pressing is used to produce a molybdenum compact. This is followed by composite sintering, low-temperature, high-deformation blanking, low-temperature cross-hot rolling, alkali cleaning, grinding, and shearing. Finally, warm rolling, hydrogen annealing, surface...
