*Minimum Order Quantity = 3 Rolls

All Foils, Inc. is an Aluminum Foil converter and distributor that carries an extensive inventory of Aluminum Foils, Copper Foils, Stainless Steel, Carbon Steel, Nickel and other exotic metals in various alloys and tempers. They offer Foil Tapes (PSA), Printed/Colored Foils, Laminated Foils and Coated Foils.

Features and Benefits of UHV Aluminum Foil:
Ultra High Vacuum aluminum foil is virtually contamination free. This means the foil is “A” wettable and completely free from oils normally found on other grades of aluminum foil. UHV foil is produced on plastic cores. Each UHV Roll is also enclosed in a free plastic dispenser box and wrapped in film. This is important for customers who require that little or no contamination infiltrates their environment.

UHV Aluminum Foil Applications: Ultra High Vacuum aluminum foil is a critical part in developing an ultra-high vacuum. Most vacuum chambers are constructed of stainless steel. When a steel vacuum chamber is opened or develops a leak, atmospheric air can enter the chamber and create a thin layer of substances. These substances include water vapors or hydrocarbons. Once the leak is repaired and the chamber closed, the left over residue will disrupt the ability to achieve a high vacuum by gradually releasing a stream of molecules as the air is pumped out. This prevents the chamber from being emptied enough to conduct proper research. To remove these substances, a “bake out” of the equipment is performed. The equipment is blanketed in UHV Foil, wrapped with electrical heat tape, and covered in foil again. The electrical heat tape is used to heat the metal chamber just enough to loosen any residues while the aluminum foil helps to spread the heat evenly.

*All Foils will certify UHV foil to the American Society for Testing and Material (ASTM) designation B-479, specification 3.1.4 and 10.3.1.
