Manufacturer profiles associated with Anode Disc/Target.
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.
Common materials include tungsten (W), tungsten-rhenium alloy (W-Re), and a molybdenum (Mo) substrate. The choice depends on the required X-ray spectrum and thermal properties.
Typical reference ranges are: target diameter 50–200 mm, target thickness 1–3 mm, disc diameter 60–220 mm, and disc thickness 5–15 mm. These must be confirmed for the specific model.
Surface roughness affects electron scattering and thermal emission. The reference range is 0.2–0.8 μm Ra per ISO 4287. Proper roughness helps maintain consistent X-ray output and thermal performance.
Check parameters such as flatness (≤0.05 mm per ISO 1101), parallelism (≤0.03 mm per ISO 1101), density (per ASTM B311), purity (per ASTM E1479), and thermal conductivity (per ASTM E1225). Always confirm with the manufacturer.
