Aluminum A2219 Standard ConFlat® (CF) UHV Flanges

Aluminum A2219 Standard ConFlat® (CF) UHV Flanges

Aluminum A2219 Standard ConFlat® (CF) UHV Flanges are lightweight, high-performance vacuum sealing components designed for ultra-high vacuum (UHV) systems. Manufactured from aerospace-grade Aluminum A2219 alloy, these vacuum flanges combine low outgassing, corrosion resistance, and excellent thermal conductivity—making them ideal for scientific instrumentation, space-grade vacuum chambers, and semiconductor processing equipment.

At TFM, we supply precision-engineered A2219 aluminum CF flanges that meet industry standards and ensure compatibility with a broad range of ConFlat vacuum components and metal gasket seals.

Key Features

✅ Aerospace-Grade A2219 Aluminum Material

Made from high-strength A2219 aluminum alloy, these ConFlat flanges are perfect for applications requiring high mechanical stability and minimal mass. A popular choice in vacuum technology used in aerospace and research.

✅ CF Standard Knife-Edge Design

Each flange features a knife-edge sealing geometry compatible with copper gaskets and standard CF components, ensuring leak-tight UHV connections even in high-temperature or cryogenic systems.

✅ Lightweight and Non-Magnetic

Compared to stainless steel flanges, aluminum UHV flanges offer a significant weight reduction and are naturally non-magnetic, ideal for electron microscopy, magnetically-sensitive devices, and particle accelerators.

✅ Excellent Thermal Conductivity

A2219 aluminum offers superior thermal transfer, beneficial in heat-sensitive vacuum environments, improving system stability and reducing thermal gradients across vacuum joints.

✅ Corrosion Resistant and Cleanroom Friendly

These flanges resist corrosion in dry UHV environments and are suitable for cleanroom operations, making them ideal for nanotechnology, vacuum optics, and photonics research.
