Atlas Aluminum vacuum chambers have excellent high vacuum (HV) and ultra high vacuum (UHV) properties. For many applications, aluminum is a superior UHV chamber material offering less H2, H2O, and hydrocarbon vapor at HV and UHV levels and less carbon contamination than stainless steel. This reduces the amount of carbon-based gas contamination in vacuum. Atlas manufactures UHV aluminum chambers with a thin, dense aluminum oxide coating. This serves as a resistive barrier, reducing diffusion and desorption of HV and UHV contaminates. Once baked, Atlas’ aluminum vacuum chambers generally cycle to HV and UHV levels faster than stainless steel chambers and require less pumping.
- 7 orders of magnitude less H2 than stainless for ultra pure vacuum
- Less carbon for reduced contamination
- 10x the thermal conductivity and 21x the thermal diffusivity for fast, complete bake outs and unmatched thermal performance
- Outgassing rates of less than 1 x 10-13 Torr liter/sec cm2 (suitable for extreme high vacuum)
- High resistance to a variety of chemicals
- The option to be anodized for electrical or chemical resistance
- Low Z (low nuclear activation) for less residual radiation
- Non-magnetic for applications that require it
- High vibration dampening (low Young’s modulus) for increased absorption
- 1/3rd the weight for superior manageability
- Lower material and operations cost for an improved bottom line
- Machinability up to 10x faster than stainless steel for lower manufacturing costs
