Atlas CFTI™ All-Metal UHV & XHV Sealing for Non-Magnetic Titanium Vacuum Chambers

The Atlas CFTI™, Time-tested reliability of the ConFlat® (CF) with body and knife-edge seal Titanium (TI). Weld the CFTI™ flange to Titanium vacuum chamber it becomes a completely Non-Magnetic.

Non-magnetic Titanium vacuum chambers will not interact with magnetic environments. Non-Magnetic vacuums are used for UHV synchrotron and particle physics and industrial applications, and XHV for quantum physics study. Such applications include non-magnetic beam tubes, wigglers, ungulator, free electron lasers (FEL), drift tubes, spectrometers.

Light/Low weight Atlas CFTI™ Flanges: For weight sensitive applications such as Aeronautical, Space or portable systems. Wight to volume ratios are 1/3 that of stainless flanges. Vacuum chambers engineers can significantly reduce overall weight of vacuum chambers The exceptional vacuum properties of titanium are within reach: The Atlas CFTI™ Flange provides standard all-metal-sealing for titanium vacuum chambers. It enables vacuum engineers and designers to fully utilize the exceptional UHV & XHV properties of Titanium.

  • The Atlas CFTI™ Flange—the Titanium flange with a titanium knife-edge seal
  • Atlas CFTI™ Flanges are suitable for service in vacuum levels to 1×10-13+ Torr and 450°C bake-out temperatures. Our titanium flanges can be welded to Titanium vacuum vessels and are the key to successful integration of Titanium UHV & XHV technology in your application.
  • Atlas titanium flanges are fully compatible with the industry standard ConFlat® flange interface. Employing CERN’s innovative 20° back-bevel (90° included angle) (Figure 1) knife-edge design, the Atlas CFTI™ Flange provides a longer service life than conventional CF flanges
