All-Titanium CF Flanges

Non-Magnetic UHV & XHV Conflat Titanium Flanges

Atlas Titanium ConFlat Flanges feature the reliability of the industry-standard CF knife edge. Weld the titanium flange to a titanium vacuum chamber, and it becomes a completely non-magnetic system. Titanium vacuum chambers with titanium flanges ensure no environmental magnetic interaction and deliver extraordinary vacuum performance.

Applications:

• UHV synchrotron
• Particle physics
• Industrial applications
• XHV quantum physics
• Beam tubes
• Wigglers and undulators
• Free electron lasers (FEL)
• Drift tubes
• Spectrometers

Light/Low Weight Atlas Flanges:

• Ideal for weight sensitive applications such as aerospace or portable systems
• Weight-to-volume ratios are 1/3 that of stainless steel flanges
• Significantly reduces overall weight of vacuum chambers
