High and ultra-high vacuum chambers have traditionally been made from stainless steel, while aluminum chambers provide customers a superior material for a wide number of reasons. Aluminum chambers deliver less carbon contamination, reducing the amount of carbon-based gas that accumulates inside the vacuum chamber. With seven orders of magnitude less hydrogen permeation than stainless steel, these chambers have much less H2, H2O, and hydrocarbon vapor at the highest levels of vacuum.
Chambers are designed and manufactured in the U.S. using a very thin, yet dense aluminum oxide coating that further provides a resistive barrier to reduce diffusion and desorption of hydrogen, oxygen, and carbon contaminates. This design feature means that these chambers cycle to high and ultra-high vacuum levels much faster than stainless steel chambers, requiring less pumping – saving time and energy costs.
Additional features include: a non-magnetic chamber for special applications, greater thermal conductivity and thermal diffusivity for fast and complete bake outs, very low outgassing rates, high chemical resistance, high vibration damping specifications, and a third of the weight for easy installation and manageability.
Atlas Technologies have been involved in enhanced vacuum technology products and services for over twenty years and have developed unique manufacturing and coating technologies to advance the industry. The company’s bimetallic technology allows them to offer aluminum flanges with robust industry standard stainless-steel knife edges. This enables UHV all-metal seals on aluminum chambers. Additionally, the bimetallic technology can solve many of the most challenging problems found in the industry. The company provides standard products as well as custom and semi-custom capabilities to its customers.
