Atlas Technologies Aluminium and Titanium Vacuum Chambers, Bimetallic Vacuum Fittings

Who We Are: Innovation, Quality and Service. Founded in 1994, Atlas Technologies has developed many of the products which have led to the aluminium ultra high vacuum (UHV) revolution and to the frontiers of titanium. We pride ourselves in developing new products that better serve you, our customers. Our bimetallic technology aids us in solving some of your most difficult challenges and helps you think about your project with more options than just stainless steel.

Aluminium Vacuum Chambers have superior vacuum performance to stainless steel chambers. Atlas Technologies helps you get the most in Aluminium in HV and UHV.

Atlas Technologies product line

Bi-Metallic fittings –ISO, CF, Face Seal, Custom

Atlas has a standard range of vacuum fittings and flanges.

The Atlas Flanges combine the time-tested reliability of the stainless steel, with an aluminium flange body for welding to an Aluminium chamber or to Aluminium tube.

Titanium Flanges – CF

The Titan CF Flange provides standard all-metal-sealing for titanium vacuum chambers. It enables vacuum engineers and designers to fully utilize the XHV high and UHV properties of titanium.

Titanium Foil Window Flange

An ultra-thin aluminum or titanium UHV window that allows for quick, inexpensive replacement in the field. An excellent alternative to beryllium.

Wire Seals

When size requirements for demountable flanges exceed that of standard Atlas CF™ flanges, Atlas Wire Seal flanges are the choice. These large, lightweight flanges enable you to utilize the many superior vacuum, physical, chemical and nuclear properties of UHV aluminium vacuum chambers.

Aluminium Chambers


Cylindrical chambers can be fabricated from standard off-the-shelf tube and pipe, or custom diameter aluminium roll-ups. An extensive selection of standard tube wall thicknesses is available. Tube and pipe wall thickness will be according to the diameter and schedule selected. Custom roll-up chambers are made from aluminium plate and are typically 5000 series aluminium alloy. All cylindrical chambers can be made with minimum wall thicknesses because of the inherent strength offered by tubular geometry.


Spherical and hemispherical Spun/Formed chambers are usually made form 5000 series Aluminium alloy. These chambers offer minimum internal surface area and radially mounted flange axes converge and focus to a central or strategic target point inside the chamber. Spun chambers can be very large and size is only limited by spinning/forming equipment capacity. These chambers offer maximum strength and minimum wall thickness


Monocoque chambers are machined from solid Aluminium alloy 5000 and 6000 series billet or thick plate. Forged material is often used to eliminate the risk of vacuum leak paths entrapped by the billet forming process—other methods can use cast micro-structure Aluminium. Aluminium is available in extremely thick plates (40” or 1016mm). Monocoque chambers enable internal and external machining, which can provide a high concentration of design features, a minimum surface area and a maximum surface quality without weld oxide contamination. Precise component location is achieved, because these are controlled in a single machining setup and welding related distortion can be eliminated. Elaborate internal mounting brackets and shapes can be included in monocoque chamber designs.


Plate-to-Plate chambers are constructed using Aluminium alloy 5000 and 6000 series stock plate. Chambers manufactured by this technique can be very large. Unlike stainless steel, Aluminium plate is available in very large sections. Off-the-shelf plate can be 48” or 60” x 144”. Atlas can supply even larger plates and chambers made from materials joined together by Atlas. Plate thicknesses are selected according to vacuum deflection calculations. Large rectangular O-ring sealed access doors or polycarbonate windows can be included in the design.


Extruded chambers are typically used for long chamber applications. However, intricate internal and external shapes can be economically added to other chamber types. Many synchrotrons require multiple chamber sections, each measuring between 4 to 8 meters in length. Extruded Aluminium fabrication is ideal and has been used for these applications, because of cost and Aluminium’s ability to handle high heat loads and its resistance to photo-desorption of surface gases.
