All-Aluminum ISO Flange
Atlas Technologies’ precision-machined All-Aluminum ISO Flanges are ideally suited for high vacuum (HV) applications in semiconductor, magnetic, nuclear, medical, portable, aerospace and chemically corrosive environments. They are manufactured to exceed HV standards and offer superior vacuum performance in what has traditionally been a stainless steel market.
Diagrams & Variations
ISO Quick Release weldable flanges are designed to ISO 2861/1 flange specifications and are compatible with existing third-party ISO flanges and components. The weld neck portion of our weld neck line is thicker than stainless ISO Quick-Release flanges and other aluminum ISO’s copied from stainless models. Additionally, our ISO Quick Release Flanges have generous weld preps to assist welding and improve vacuum integrity.
Atlas Technologies all aluminum ISO Quick-Release flanges are fully compatible with existing third-party ISO flanges and hardware.

Advantages of Aluminum over Stainless Steel
Advantages of Aluminum over Stainless Steel in UHV 10x the thermal conductivity and 21x the thermal diffusivity for fast, complete bakeouts and unmatchable thermal performance 7 orders of magnitude less H2 for ultra pure vacuum Less carbon for reduced contamination Outgassing rates of less than 10-13 Torr liter/sec cm2 suitable for extreme high vacuum Non-magnetic … Continued
Aluminum’s Extreme Vacuum Performance
Aluminum’s Extreme Vacuum Performance Any single physical or chemical property of aluminum may be enough reason to select aluminum as a vacuum chamber choice over stainless steel. But when looked at in summary, aluminum overwhelmingly surpasses stainless steel as providing the lowest cost of ownership. Aluminum has seven orders of magnitude less hydrogen than stainless … Continued
