Dissimilar Metal Bonding and Joining

Our bonds have been used in some of the highest man-made vacuums ever produced (<1 x 10-14 Torr) and in the most difficult to seal applications (super fluidic helium, for example). Our parts are used extensively in semiconductor fabrication, particle physics, medical, nuclear, cryogenic, oil and gas, and many other applications.

UHV and XHV Ingenuity

Ultra high vacuum and extreme high vacuum is quite a bit different than lower vacuum regimes. The vacuum chamber material, its geometry, pumping methods, and conductance play a huge role in the quality of the vacuum. We have designed and manufactured a wide variety of UHV and XHV vessels for many different applications, ranging from industrial OEMs to national laboratories and to universities. We know vacuum!

Aluminum Vacuum Innovation

Aluminum vacuum is our core. Back in the mid-90’s we pioneered the use of aluminum for UHV and XHV applications around the globe. We invented the Atlas bimetal flange which allowed researchers and technologists to take advantage of the many favorable qualities of aluminum, converting large segments of their systems to this alternative superior metal, while retaining conventional industry standard stainless knife-edge flanging to UHV and XHV.

With advanced joining, surface treatments, and coating techniques we continue to lead the vacuum industry by applying the excellent vacuum properties of aluminum.

High-Performance Materials

We LOVE materials! We find there are so many design opportunities that open up when you understand and apply materials effectively. Most of the vacuum industry is entrenched in the misguided belief that stainless steel is the ultimate material for vacuum. Because of this, most vacuum chambers are made with stainless when, in fact, stainless is a poor choice for UHV and XHV. Aluminum, titanium, copper and many other materials can have superior vacuum properties to stainless steel. Chambers made with these materials outperform stainless on many levels.

Vacuum Design & Engineering

Vacuum design has its subtleties. The material, geometry, pumping method, pump access, weld locations, gasketing and flanging all affect the quality of your vacuum and its cost. With Atlas' vacuum design and engineering we can help you make the best choices to balance these subtle factors to get you the vacuum you are looking for. Our fluency in vacuum materials will give you more opportunities to innovate. Contact us to start a conversation about your vacuum goals and design options.

Advanced UHV Surfaces

The surface of the vacuum chamber has a huge impact on the quality of vacuum. Atlas created a suite of surfaces treatments that enable you to have greater control of the surface of your vacuum vessel. Emissivac reduces thermal transmission while decreasing surface area and this enhances vacuum performance. Our passivation treatments create a thin dense oxide with improved vacuum performance by reducing oxide porosity. Our nano-plating technology can add novel materials and novel material properties to the surface of many materials.
