Product Overview
Grade 3 titanium wire is a commercially pure titanium wire with higher strength than Grade 1 and Grade 2 while still maintaining very good corrosion resistance. It is used when additional strength is needed for corrosion-resistant wire products, industrial fabrication, and formed-wire components, while keeping good weldability and reasonable formability.

Notes and Precautions
- Grade 3 provides higher strength but reduced formability compared with Grade 1/2; confirm bending radius and forming route before production.
- Maintain clean handling and storage to avoid surface contamination that can affect corrosion performance and welding.
- For welding, use appropriate filler selection and full inert gas shielding per your WPS.
