Alloy Grade 1 / 3.7025
Unalloyed titanium offering optimum ductility and cold formability with useful strength, high-impact toughness and excellent weldability. This makes this grade suitable for the manufacture of components in weight-saving structures with reduced mass forces and also for components requiring high corrosion resistance. In addition, thermal stresses in titanium structures are lower than in other metallic materials, due to the low thermal expansion of titanium.
Main areas of application for titanium Gr 1
For corrosion resistance in the chemical and maritime industries; in aircraft construction, where easy formability is desired; also widely used in the medical field due to its excellent biocompatibility.

Welding filler material (for welding with titanium Gr 1)
Grade 1 has very good weldability. Since it is essentially a single-phase material, the structure of the alpha phase is not significantly affected by heat treatments or welding temperatures. Therefore, the mechanical properties of a correctly welded joint correspond to those of the base material or even exceed them and exhibit good ductility.
