Precision titanium capillary tubes are ultra-small diameter, thin-wall titanium tubes manufactured for applications requiring exceptional dimensional accuracy, surface quality, corrosion resistance, and mechanical reliability.

Changsheng Titanium specializes in the production of high-precision titanium capillary tubing, including ultra-fine diameter tubes, ultra-thin-wall tubes, and micron-level precision capillaries.

Titanium Grade 1 (Gr1 / TA1) is one of the most commonly used materials for precision capillary tubes due to its excellent ductility, formability, corrosion resistance, and biocompatibility. With relatively low oxygen and iron content, Gr1 titanium offers superior plasticity compared with higher-strength titanium grades.

Our precision capillary tubes are widely used in medical devices, aerospace equipment, automotive sensors, optical communication systems, precision instruments, and other high-performance applications.
