Titanium Grade 1

Trade name	Ti 1

Standards

Material No.

3.7025

EN Designation

Titan Grade 1

ASTM

Ti-Grade 1

UNS

R50250

Description	Ti-Grade 1; Unalloyed Titanium - Low Oxygen

Special properties	Commercially pure titanium grades feature an excellent strength-to-density ratio and good corrosion resistance. This makes them 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. The materials are also widely used in the medical sector because of their outstanding biocompatibility.
