Low CTE / ZTE Square Tubing

Low CTE / ZTE Square Tubing

Near Zero CTE ◾ Proven Success ◾ Testing Verified ◾ 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. 

Rock West offers value added testing of round & now square composite tubing for CTE, bend and twist. Let us know if that is of interest to you or your team.
