Using proprietary and state-of-the-art explosion bonding technology, Atlas CF bimetallic flanges are fully compatible with the industry standard Conflat flange interface. The flange incorporates the CERN innovative 20° back-bevel (90° including angle) knife-edge design, which increases overall service life over conventional CF flanges. The flanges operate in high, ultra-high, and extremely high vacuum applications where vacuum levels to 1x1013 Torr and 250°C bake-out temperatures are required.
The Atlas CF Flange can be easily welded to aluminum vacuum vessels, making them a key component to successful integration of aluminum UHV technology to an application. In neutron applications such as the production of radioisotopes for medical imaging, aluminum vessels fitted with Atlas CF Flanges help to reduce residual, neutron-induced radiation. These flanges also allow customers to incorporate UHV systems in cyclotrons and nuclear reactors.
Other features of the CF Flange include a rotatable collar, a mechanical EXW interface, and a two-thirds weight decrease from stainless steel only flanges. The flanges are vacuum leak tested at the factory. The mechanical interface between bonded metals has a tensile strength of 15,000psi and a shear strength of 10,000psi.
