Atlas warranties products for one year from the shipping date, provided products are installed and used within recommended operational conditions. All products are shipped ExWorks; thus, the customer assumes ownership when it leaves our facility. Warranty coverage is limited to actual repair or replacement of the part or assembly with no peripheral coverages.

With the exception of parts being returned for repair or replacement under standard warranty coverage, Atlas products are sold under No Cancellation, No Returns (NCNR) terms. Occasional exceptions are made for standard catalog products still sealed in their original packaging. 

To return parts for repair or replacement under standard warranty coverage, please contact the Atlas sales team at info@atlasuhv.com to request an RMA number. Return shipments that are not accompanied by an Atlas RMA number will not be accepted. 

Our company was founded in 2010 with a mission to deliver quality products worldwide.

Atlas Technologies was started in 1994 by father-and-son team Richard and Jed Bothell. The company remains a family-owned entity. Read the whole story at https://www.atlasuhv.com/our-history.

We design, develop, and manufacture aluminum and titanium vacuum chambers and a variety of bimetal components. Specialty solutions include Atlas Emissivac finishing for aluminum chambers and the capability to machine and weld a multitude of bonded dissimilar metal components. 

Atlas is careful to avoid disclosing customer-specific information, which allows us and our customers to maintain competitive advantage and mutual trust. A non-disclosure agreement applies to most custom projects. When placing an order, ask your Atlas representative for more information.

Yes. Welding aluminum is a little different than other metals. For example, stainless steel glows orange at welding temperature, while aluminum does not change color. Therefore, careful preheating is critical, as is carefully watching your weld puddle. Learn more in our handy aluminum welding guide.

Common bonds include:

• Aluminum to stainless
• Aluminum to titanium
• Titanium to stainless
• Copper to stainless
• Niobium to stainless

Other combinations are also available. 

• Aluminum/Stainless = Aluminum 6061 > Titanium > Copper >Stainless Steel. Aluminum/Stainless is also available with a chrome (copper free) layer for applications which require zero or minimal copper contamination
• Titanium/Stainless = Titanium > Tantalum > Stainless Steel

Thicknesses and bonding methods are proprietary as we have thoroughly tested the effectiveness and performance of each bond type.

Aluminum is lightweight, non-magnetic, easy to machine, contains limited hydrogen and carbon contamination, and offers excellent thermal control. Additional benefits include significant vibration dampening, reduced radiation, and better bakeout.  Learn more.

Extreme High Vacuum (XHV) represents the most extreme vacuum level possible, below 1×10¹² Torr which is much higher vacuum than Ultra High Vacuum (UHV). XHV simulates the vacuum of deep space by removing almost all gas particles from a sealed chamber and is used for top-tier scientific research and quantum computing. Aluminum and titanium are typically more viable materials to achieve XHV.

A metallurgical bond is a high-strength, atomic-level connection formed when atoms from two metal surfaces blend to create a unified, solid interface. The resulting joint is often as strong as or even stronger than the original metals themselves.

Atlas defines bimetal as two dissimilar metals hermetically bonded to each other. It is also referred to as bonded dissimilar metal.

Aluminum chambers are used in physics research, quantum computing, ion trapping, x-ray projects, cryogenic applications, telescopes, space test facilities, rocket thrusters, semiconductor fabrication, and more. Primary reasons for using aluminum and titanium chambers include low hydrogen content, reduced contamination, non-magnetic properties, zero-radiation, x-ray transparency, thermal conductivity and light weight. 

Yes. Nearly everything we build at Atlas needs to be leak checked, so we're experienced and proficient at this process. Our bonds and welds are leak tested to minimum 1.0x10⁻⁹ Torr x L/second using Pfeiffer ASM 392, ASM 340D and ASM340I leak check machines. Multiple high capacity and turbo pumps are available to pump out large chambers. More information here.

Yes. Atlas bonds and welds are leak tested to minimum 1.0x10-9 Torr x L/second using Pfeiffer ASM 392, ASM 340D and ASM340I leak check machines. More information here.

An Atlas ATCR or ATCRBI is a Bimetal Face-Seal Fitting featuring a durable, stainless steel sealing face hermetically bonded to an aluminum body. This enables robust, demountable use of aluminum tubing in cryogenic, physics, semiconductor, and other applications. Titanium Face Seal Fittings are also available. ATCRs are fully compatible with Swagelok VCR® fittings.  

A ConFlat (CF) flange is used to connect vacuum chambers, tubing, and vacuum pumps to each other while maintaining UHV pressure. The flanges feature a sharp knife edge that allows two identical flanges to compress a soft copper gasket between them to create a leak-tight, bakeable seal. They are crucial in scientific and industrial vacuum systems. Atlas CFBI and CFTA ConFlat (CF) flanges feature an aluminum body with a stainless steel or titanium knife edge feature that enables aluminum or titanium vacuum chambers to connect to stainless steel components outside the chamber. Solid titanium ConFlat (CF) flanges are also available.

An Atlas CFBI is a Bimetal Al/SS ConFlat (CF) Flange, an aluminum flange with a stainless steel knife edge for dependable UHV and XHV sealing performance. Titanium/Aluminum (CFTA) ConFlat (CF) Flanges and All-Titanium (TICF) ConFlat (CF) Flanges are also available. 

A Swagelok VCR (Vacuum Coupling Radius) is a stainless steel fitting designed for metal-to-metal face seal fitting in vacuum applications. It uses a deformable metal gasket between two gasket beads (glands) to provide a seal, and it’s often used in semiconductor, chemical, and research industries to prevent contamination.
