Introduction of Tungsten Alloy Disc

Tungsten alloy discs are primarily composed of tungsten, combined with other metal elements such as nickel and iron through a specific process. One of the most significant characteristics of tungsten alloy discs is their high specific gravity. Their density typically ranges from 16.5 to 18.75 g/cm³, significantly superior to common metals. Tungsten alloy discs exhibit excellent stability in high-temperature environments due to their high melting point and excellent heat resistance. While their melting point can reach around 3400°C, many metals would melt and deform at such high temperatures, but tungsten alloy discs maintain their original physical form and mechanical properties. Tungsten alloy discs possess high strength and hardness, making them resilient in the face of various external forces. Their tensile strength typically reaches 900-1100 MPa, and their hardness is also relatively high, ranging from 25 to 35 HRC. These high strength and hardness make them excellent at resisting wear and impact. Tungsten alloy discs also possess excellent electrical and thermal conductivity, making them a valuable energy transfer tool in electronic devices and heat sinks. Electrical conductivity is a key performance indicator in electronic devices. The excellent electrical conductivity of tungsten alloy discs makes them widely used in the manufacture of...

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,...
