Ultra High Vacuum (UHV) Aluminum Foil

Ultra High Vacuum (UHV) Aluminum Foil

Ultra High Vacuum (UHV) Aluminum Foil: Engineered Cleanliness for High-Vacuum Environments

Ultra High Vacuum (UHV) Aluminum Foil from TFM is specially produced to meet the rigorous cleanliness standards required in UHV systems and cleanroom operations. Unlike standard household or industrial foil, this foil is completely free of oils, silicones, or processing residues, making it the trusted choice for high-sensitivity environments such as semiconductor manufacturing, analytical labs, and vacuum coating systems.

Why Choose Ultra High Vacuum (UHV) Aluminum Foil?

  • Contamination-Free Design: Each roll of Ultra High Vacuum (UHV) Aluminum Foil is manufactured and handled in a way that guarantees a virtually contaminant-free surface. It is “A” wettable, meaning it can be reliably used with vacuum-compatible cleaning agents and remains free of any oils found in conventional aluminum foil products.

  • Certified to ASTM B-479 Standards: TFM’s UHV aluminum foil complies with ASTM B-479, specifically meeting sections 3.1.4 and 10.3.1, which cover material purity and mechanical specifications suitable for critical vacuum applications.

  • Ideal for Controlled Environments: This Ultra High Vacuum (UHV) Aluminum Foil is purpose-built for cleanrooms, vacuum chambers, space simulation systems, and thin film processing equipment, where molecular-level cleanliness is non-negotiable.

  • Protective Packaging for Integrity: To maintain its ultra-clean state, the foil is rolled on non-contaminating plastic cores, housed in a sealed plastic dispenser box, and additionally wrapped in film — ensuring it’s pristine and ready for direct use in vacuum environments.

  • Versatile High-Vacuum Utility: Whether lining vacuum chambers, shielding delicate instrumentation, or isolating experimental surfaces, Ultra High Vacuum (UHV) Aluminum Foil delivers consistent performance and purity.

Applications of Ultra High Vacuum (UHV) Aluminum Foil:

  • Lining walls and internal components of UHV chambers

  • Shielding against thermal radiation and deposition in sputtering and evaporation systems

  • Wrapping or isolating clean tools or fixtures in ISO-class cleanrooms

  • Serving as a physical barrier to reduce particulate accumulation during equipment maintenance

TFM’s Ultra High Vacuum (UHV) Aluminum Foil is a critical consumable for any laboratory or facility operating in ultra-clean or high-vacuum conditions. By eliminating contamination risks and offering ASTM-backed quality, it supports both operational efficiency and system longevity in advanced material processing and vacuum science.

FAQ

Tube fittings are designed for tubes (measured by outside diameter and wall thickness) used in high-pressure and instrumentation applications, whereas pipe fittings are for pipes (identified by nominal pipe size) primarily used in fluid transport.

 

Common valve types include ball valves, gate valves, check valves, butterfly valves, and globe valves. Each serves a specific function—from quick shutoff (ball/gate valves) to flow regulation (globe valves).

 

  • For tubing, measure the outside diameter; for pipes, refer to the nominal pipe size (using conversion charts if needed). Always match the valve or fitting size to your pipe’s dimensions and flow requirements.

  • Frequently used thread types include NPT (National Pipe Tapered), BSP (British Standard Pipe), and UNC, along with slip-fit options that rely on compression or fusion rather than threads.

Interchangeability depends on manufacturer specifications and certification. Always verify compatibility via manufacturer guides or certified interchangeability charts.

 

  • A coupling is a short, straight fitting used to join two pipes or tubes. It provides a secure, leak-tight connection and can sometimes serve to extend or repair piping runs.

Consider valve type, pressure and temperature ratings, material compatibility with your fluid, actuation method (manual or automatic), and maintenance requirements.

 

  • Valves regulate flow by opening, closing, or partially obstructing the pathway. Their mechanisms (such as the rotation of a ball or the linear movement of a gate) determine the speed and precision of flow control.

  • A flange is a flat, circular component used to connect pipes, valves, or other equipment. Bolted together with gaskets, flanges provide a secure, leak-proof joint that facilitates both assembly and maintenance.

  • Manual valves require physical operation via handles or levers, whereas actuated valves use mechanisms—pneumatic, electric, or hydraulic—to open and close automatically or remotely.

  • Issues include leaks caused by improper installation, over-tightening, degraded seals, material incompatibility, and fatigue from repeated cycling. Regular inspection and proper installation practices help mitigate these problems.

Regular maintenance involves periodic inspections, cleaning or replacing worn seals, ensuring proper torque during installation, and adhering to manufacturer guidelines and local plumbing codes to preserve system integrity.
