When your project demands a metal that combines ultra-low weight with exceptional corrosion resistance, standard sheet stock falls short. Engineers, hobbyists, and fabricators working on aerospace components, medical device prototypes, chemical equipment, and high-end DIY builds rely on TA1 commercially pure titanium foil to deliver consistent performance where other metals corrode, fatigue, or add unnecessary mass.
Each TA1 titanium foil sheet is cut from commercially pure Grade 1 titanium (TA1 designation), offering the highest ductility and formability in the titanium family. Thickness options range from 0.1 mm to 0.4 mm (approximately 0.004 in to 0.016 in), with sheet dimensions of 200 × 240 mm (approx. 7.9 × 9.4 in) for the 0.1 mm and 0.2 mm variants, and 200 × 200 mm (approx. 7.9 × 7.9 in) for the 0.3 mm and 0.4 mm variants.
Typical use cases include titanium shim stock for precision gap-filling in mechanical assemblies, thin titanium sheet for electrochemical cell electrodes and fuel cell components, lightweight metal foil for aerospace skin repair patches, and flexible titanium panel for medical implant prototyping and biocompatible enclosures.

For flexible shim stock, gaskets, or electrode foil applications, 0.1 mm or 0.2 mm is typically sufficient. For structural patches, heat shields, or components requiring more rigidity, 0.3 mm or 0.4 mm provides better stiffness while remaining formable. If you are unsure, contact us to confirm suitability for your specific load or gap requirements.
Yes. TA1 is the Chinese national standard (GB/T) designation for commercially pure titanium Grade 1 per ASTM B265. It is the purest and most ductile titanium grade, with the lowest oxygen and iron content, making it ideal for forming, welding, and corrosion-critical applications.
TA1 titanium forms a passive titanium dioxide (TiO₂) oxide layer on its surface that is self-healing and highly resistant to seawater, chlorine, dilute acids (including hydrochloric and sulfuric acid at moderate concentrations), and most oxidizing environments. It significantly outperforms 304 and 316 stainless steel in marine and chemical processing conditions.
At 0.1–0.4 mm thickness, TA1 titanium foil can be cut with sharp metal shears, laser cutters, or waterjet. CNC milling is possible with carbide tooling and appropriate coolant. Avoid high-speed dry cutting as titanium work-hardens and generates heat. TIG or laser welding in an inert argon atmosphere is recommended for joining.
TA1 commercially pure titanium is widely recognized as biocompatible and non-toxic. It is used in medical implants, dental fixtures, and surgical instruments. While this product is intended for prototyping and fabrication use, it meets the material composition requirements of Grade 1 titanium per ASTM F67 for unalloyed titanium for surgical implant applications. Always verify compliance with your specific regulatory requirements before clinical use.
TA1 (Grade 1) has lower oxygen and iron content than TA2 (Grade 2), making it softer, more ductile, and easier to form at thin gauges. TA2 offers slightly higher strength (tensile strength typically 345–450 MPa vs. 240–310 MPa for TA1). For thin foil applications requiring bending or forming, TA1 is generally preferred. For structural sheet applications needing more strength, TA2 may be more appropriate.
Each unit ordered includes 1 sheet of the selected size and thickness. If you need multiple sheets or custom quantities for a project or bulk order, please contact us — we can accommodate larger volume requirements.
