Manufacturer profiles associated with Tungsten-Rhenium Target Disk.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The rhenium content is typically 3–10% by weight, as listed in the directory. This range improves ductility and thermal shock resistance compared to pure tungsten.
The outer diameter ranges from 70 to 120 mm, and the thickness from 1.5 to 3.0 mm. These are typical values for X-ray tube anodes and should be confirmed for the specific model.
The maximum operating temperature is 2500–2800 °C. This allows the disk to withstand the extreme thermal loads during X-ray generation.
The directory lists ASTM B760 for rhenium content and density, ISO 4287 for surface roughness, ISO 1101 for flatness and parallelism, ASTM E1225 for thermal conductivity, and ASTM E831 for coefficient of thermal expansion. These are verification references, not proof of certification.
