Aluminium vacuum chambers / Bi-metal

Atlas Aluminum vacuum chambers

Neyco offer Vacuum chambers from Atlas company (US), the specialist of aluminum vacuum chambers.

Aluminum advantages : 

• Better bakeout thanks to the thermal conductivity 
• Amagnetic (ou Non-magnetic)
• Lighter : 1/3^rd of the weight 
• Less H₂ than stainless (7 orders of magnitude)
• Less carbon for reduced contamination/stainless
• Outgassing rates <1.10^-13 mbar.l.s^-1.cm^-2

Examples of applications :

• Synchrotrons (ESRF, CERN)
• Ions or electrons beam tubes 
• Free electrons laser (FEL)

Bimetal plates and discs

Neyco provide plates, discs and other bimetal shapes. These pieces are manufactured with the EXW technology.  

• Layers numbers : 2 to 3 
• Possible combinations : Copper/Aluminum, Copper/Stainless steel, Nickel/Copper, Copper/Aluminum/Copper, Stainless steel/Aluminum/Stainless steel, etc... 
• Delivered with certificates of analysis

CF bi-metal flanges

Neyco offers two main types of CF bi-metal flanges UHV vacuum chambers :

• Titanium/Aluminium : with one Titanium part (Knife side) welded onto an Aluminium flange or connector which allows to have a non-magnetic vacuum part. ​
• Stainless steel/Aluminium : with one Stainless steel 316L/316LN part (Knife side) welded onto an Aluminium flange or connector. 

​The welding is obtained by EXW (Explosion Welding Technology) fully compatibles with UHV applications. 

These bi-metal flanges or connectors can then be directly welded on aluminium vacuum chambers.
