Tungsten-Rhenium (WRe) Alloys from Tungsten-Rhenium (WRe) are used in various compositions. The alloy element Rhenium transfers a number of interesting characteristics to Tungsten. Due to this fact the recrystallization temperature and electrical resistance is higher.

The rapidly increasing therapeutic applications of 188 Re in nuclear medicine, oncology and interventional cardiology require routine production of large, multi-Curie levels of the 188 W parent. The capability and effective coordination of back-up production sites is important to insure that high level 188 W/ 188 Re generators are continually available. . We have coordinated 188 W production ...

The tungsten-rhenium alloy bars with relative density of 92% ~ 95% can be obtained by vertical melting sintering with direct power or indirect heating sintering with cP and N induction. The best quality billet can be obtained by isostatic pressing and intermediate frequency induction heating sintering, and its uniformity and consistency are the best among all production methods.

Rhenium Tungsten Anode in X-Ray Tube The anode (or anticathode) is the component of the x-ray tubes where x-ray are produced. It is a piece of metal, shaped in the form of a disk with a diameter between 55 and 100 mm, and thickness of 7 mm, connected to the positive side of the electrical circuit.

27-12-2020· Tungsten Rhenium Wire Properties and Uses Union City. The tungsten-rhenium wire was created in efforts to develop a wire that was more ductile after recrystallization. The addition of 3% rhenium to non-sag tungsten produced a wire that is more ductile, without sacing any non-sag characteristics. Properties of Tungsten-Rhenium Wire

Pure tungsten (W), irradiated to 3.5 dpa in a target of the Swiss neutron spallation source (SINQ), was characterized using high-sensitivity HPGe gamma ray spectroscopy to identify the present radionuclides. Synchrotron X-ray absorption spectroscopy was used to quantify the amount of Re produced in …

Tungsten wire with 3%, 5%, 25% or 26% rhenium, keeps high strength, good flexibility and mechanical properties in 2000℃ temperature. And it will not become fragile after high temperature use. Tungsten-rhenium wire has the features of high melting point, good toughness, good chemical stability under the non oxidizing atmosphere, less secondary pollution.

Tungsten-rhenium wire surface is smooth, no glitches, uniform diameter. Tungsten-Rhenium Wire Production Process Preparation of raw materials - raw materials separation - mixing - reduction treatment - second mixing - Pressed Sintered - swaging, drawing processing - Finished

The feasibility of rhenium (Re) production by irradiating tungsten (W) metal in a medium size fast reactor was evaluated by using a Monte Carlo code. The fast reactor can produce about 50 kilograms of Re per every 3 years, which corresponds 10% of Japanese domestic production. The specific activity of Re can be reduced below the exemption level or even the natural Re level if W and osmium is ...

Made of tungsten alloyed with 3%, 5%, 25% or 26% rhenium, W-Re alloys become more ductile and machineable. And due to the good electrical properties, they are widely used as high temperature thermocouple materials. As the most common material, tungsten rhenium wire is used for the production of heaters for dispenser cathodes.
