CFC Channels
Max Graphite supplies CFC U-channels and L-channels in standard and custom cross-sections for vacuum furnace systems, heat treatment fixtures, hearth rail assemblies, and high-temperature structural applications across aerospace, semiconductor, and advanced materials processing. Our CFC channel profiles are manufactured from woven carbon fiber composite with a balanced 0°/90° fiber architecture, delivering consistent structural performance from ambient through extreme service temperatures. As a single-source supplier of standard stocked profiles and fully custom-machined components, Max Graphite supports procurement from development programmes through production-scale supply.
Structural Integrity at the Heart of Your High-Temperature Process
CFC U-channels and L-channels are specified wherever dimensional stability under repeated thermal cycling is non-negotiable — in vacuum furnaces, atmosphere furnaces, sintering systems, spark plasma sintering (SPS), and CVD reactors operating at temperatures that place the highest structural demands on fixture hardware. These profiles serve as hearth rails, rack frameworks, insulation fastening structures, and heating element supports in the most demanding thermal environments across aerospace, semiconductor fabrication, and advanced materials manufacturing. Max Graphite supplies both U and L profile geometries with full custom machining capability, enabling engineering teams to specify exact leg heights, widths, and wall thicknesses for application-critical fit and load requirements.
- Profile geometry and dimensional flexibility: U and L cross-sections available in standard stocked dimensions and machined to custom leg heights, widths, and wall thicknesses for application-specific assembly requirements.
- Balanced woven fiber architecture: 0°/90° fiber layup delivers in-plane isotropy and consistent mechanical properties, maintaining structural reliability across complex thermal cycle profiles.
- Crack-arrest performance under thermal load: The fibrous composite structure prevents crack propagation, maintaining load-bearing capacity across thermal cycles where monolithic alternatives can fail progressively.
- Low thermal mass for process efficiency: The high strength-to-weight ratio of CFC channel profiles reduces furnace loading weight, supports faster cycle times, and enables tighter part tolerances by minimising fixture-induced thermal distortion.
- Engineering and qualification support: Max Graphite works with engineering and procurement teams prior to production to confirm geometry, fiber grade, surface condition, and dimensional tolerances — supporting first-article qualification and volume production transitions.
