Thin Wall Gr2 Titanium Tubing

Thin Wall Gr2 Titanium Tubing is a precision tube manufactured from Grade 2 commercially pure titanium (UNS R50400) with a relatively small wall thickness compared to its outside diameter. It combines excellent corrosion resistance, high strength-to-weight ratio, and outstanding weldability, making it an ideal material for applications where lightweight construction, dimensional accuracy, and long service life are critical.

Thin-wall titanium tubing is typically produced through cold drawing and precision sizing, ensuring tight tolerances, smooth surface finishes, and consistent mechanical properties. Compared with conventional steel or stainless steel tubing, Gr2 Titanium Tubing weighs approximately 40% less while offering superior resistance to seawater, chlorides, acids, and many aggressive chemical environments.

Gr2 seamless titanium tubing shows good corrosion resistance in many media, especially in oxidizing, neutral and weakly reducing media. This is because titanium has a strong affinity for oxygen and can form a dense oxide film on the surface to protect the substrate from corrosion. This oxide film maintains its properties even at high temperatures.
