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 (e.g. super fluidic helium). Our parts are used extensively in semiconductor fabrication, particle physics, medical, nuclear, cryogenic, oil and gas, and many other applications.
Our Technology
Dissimilar Metal Bonding and Joining
UHV and XHV Ingenuity
UHV and XHV vacuum is quite a bit different than lower vacuum regimes. Vacuum chamber material, chamber geometry, pumping methods, and conductance all 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 universities. We know vacuum!
Aluminum Vacuum Innovation
High-performance aluminum vacuum is at the core of Atlas. 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 and convert large segments of their systems to this superior alternative.
With advanced joining, surface treatment, and coating techniques, we continue to lead the vacuum industry by utilizing the superior 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 science effectively. Much of the vacuum industry still mistakenly believes that stainless steel is the ultimate material for vacuum. Consequently, 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 have superior vacuum properties when compared to stainless steel, and chambers made with these materials outperform stainless on many levels.
Vacuum Design & Engineering
Vacuum design has its subtleties. Material choices, geometry, pumping methods, pump access, weld locations, gasketing, and flanging all affect the cost and quality of your vacuum. With Atlas' vacuum design and engineering expertise, we can help you make the best choices to efficiently balance these factors and get you the vacuum performance you are looking for.
Advanced UHV Surfaces
The interior surface of the vacuum chamber has a huge impact on the quality of vacuum. Atlas has created a suite of surfaces treatments that enable you to have greater control over the surface of your vacuum vessel. Our proprietary passivation treatments remove the natural, porous oxide layers and replace them with a thin, dense oxide layer, resulting in enhanced vacuum performance.
