	Low Permeability Chambers and Flanges

Atlas Technologies builds a non magnetic model of its Atlas Flange TM , the aluminum flange with a stainless steel knife-edge and face using 316LN stainless. This alloy ensures a minimal magnetic permeability from the stainless steel while providing an aluminum base for weld-up to an aluminum chamber that is not magnetized during welding. The magnetic permeability of aluminum, near unity, and its excellent vacuum properties such as extremely high thermal conductivity, low H2 and no C content, light weight and low Z make aluminum a superior vacuum material for many UHV applications.   See our section on aluminum vacuum properties for more information.

Atlas also manufactures Atlas Flanges with hardened knife edges and faces using materials other than stainless. For example Atlas uses titanium instead of stainless as a knife edge material.  This reduces the magnetic permeability even more than using 316LN and is ideal for extremely magnetically sensitive applications.

Some non magnetic applications are better served with copper Ultra High Vacuum UHV chambers and flanges.   Atlas manufactures custom copper chambers with hardened flanges surfaces to meet your specifications.

Low permeability Atlas CF Flanges and chambers are in use at prominent national lab and accelerator facilities world wide. We would be delighted to talk with you about your application and assist you in the engineering and manufacture of flanges or chambers.
