cf f flange
The CF F flange is a critical vacuum component designed for high-performance sealing applications in ultra-high vacuum (UHV) systems. This specialized flange follows the ConFlat (CF) standard, featuring a knife-edge sealing mechanism that creates reliable, leak-tight connections essential for scientific research, semiconductor manufacturing, and analytical instrumentation. The CF F flange utilizes a copper gasket compressed between two knife edges to achieve exceptional vacuum integrity, capable of maintaining pressures down to 10^-13 mbar. The flange design incorporates precision-machined stainless steel construction, typically using 304 or 316L grade materials for superior corrosion resistance and durability. The CF F flange nomenclature indicates specific dimensional standards within the ConFlat family, ensuring interchangeability and compatibility across different vacuum system components. Its bolt-hole pattern and overall dimensions adhere to internationally recognized standards, facilitating seamless integration with pumps, chambers, gauges, and other vacuum hardware. The technological features of the CF F flange include symmetrical design for uniform stress distribution, non-magnetic properties for sensitive applications, and bakeable construction allowing thermal processing up to 450 degrees Celsius for outgassing reduction. Applications span particle accelerators, mass spectrometry systems, surface science equipment, thin-film deposition chambers, and electron microscopy installations where contamination-free environments and absolute vacuum integrity are paramount requirements for successful operations.
