Low CTE / ZTE Square Tubing

Low CTE / ZTE Square Tubing

Square Composite Tubing ◾ POS/NEG Low CTE / ZTE ◾ Carbon Fiber ◾ Constantly Expanding Offerings

Whether your project is big or small, we are bound to have (or are able to build) a product that suits your needs. Since this category is new, we are eagerly looking to add new Low CTE (Coefficient of Thermal Expansion) tubing. If you don't see it here, that doesn't mean we don't have it! Smaller diameter tubes listed here (<~1.25") may be more sensitive to twist due to thermal variations however it can be generally assumed that CTE (we sometimes call it ZTE for Zero Thermal Expansion) is less than 1 ppm /°C. In some cases and larger diameters (~2.00") we see CTE values below 0.3 ppm /°C. Note, tubes with unidirectional outer plies may exhibit slightly lower CTE values though not yet quantified per comparing a family of square tube diameters. 

Low CTE / ZTE Applications:

  • optical benches
  • metering structures
  • measuring devices
  • medical devices
  • test fixtures, and
  • other precision applications

Low CTE / ZTE Carbon Fiber Square Tube Highlights:

  • Allows for the "clocking" of your product or assembly
  • Majority "Off-Axis" plies allow for a nicely balanced layup. Majority of products contain ~50% +/-45° plies and a blend of 0°'s
  • Easily mount equipment & hardware to the ID or the OD
  • Standard dimensions allow for easy component machining if / when needed
  • Radius corners allow for efficient stress transfer plus;
  • Let's just say it, they're just plain good looking
