How Vacuum Aluminum Foil Supports Contamination Control in UHV and Cleanroom Environments
When it comes to maintaining precision in controlled environments, vacuum aluminum foil plays a vital role in minimizing contamination and supporting the integrity of ultra-clean systems. Specializing in light gauges and narrow widths, we offer expertly slit rolls of aluminum, copper, and stainless steel—down to .0002" thick and .100" wide—to meet the most demanding cleanroom and ultra high vacuum aluminum foil requirements. Our team also provides custom foil programs tailored to fit your unique application and environment.
Features and Benefits of UHV Aluminum Foil:
Our UHV aluminum foil is virtually contamination-free and specifically engineered for critical applications. Unlike standard grades, UHV foil is “A” wettable and completely free of surface oils, making it ideal for use in cleanrooms and vacuum systems. Each roll is wound on a plastic core, sealed in a plastic film, and packaged in a clean dispenser box—ensuring no exposure to external contaminants during transport or handling.
Applications of UHV Foil in Ultra-High Vacuum Systems:
In vacuum technology, maintaining a molecularly clean environment is essential. Ultra high vacuum aluminum foil is commonly used during equipment “bake-out” procedures, where stainless steel vacuum chambers are wrapped in foil and heat tape to remove water vapors, hydrocarbons, and other residual gases. The vacuum foil evenly distributes heat and prevents atmospheric interference, helping technicians achieve the high vacuum levels necessary for research, testing, or semiconductor processes.
Whether you're outfitting a lab, research facility, or production site, our precision-cut, contamination-controlled UHV foil supports your efforts to achieve optimal vacuum integrity and cleanliness.
*Many of our materials meet industry specifications including DFARS, REACH, RoHS, and various MIL-SPECs. We do not charge a fee for issuing this documentation or Certificates of Compliance. UHV-Ultra High Vacuum foil is suitable for use in clean-rooms and vacuum chambers. Wrapped in plastic and packed in a plastic box, this foil is "A Wettable" per ASTM B-479 Para. 3.1.4 & 10.3.1. It is also meets QQ-A-1876 Type 1 Grade B tested using the Aluminum Standard Association's test method certified by our mill. Coils are tested individually during our production process for compliance to the "A Wettable" condition.
