Titanium filler metals

Ti-Gr. 5 ELI: Ti6Al4V with extra low interstitial elements content, with enhanced ductility, typically used in the non aged condition for maximum toughness. Widely used for cryogenic devices as well as medical applications.

Excelent weldability, and can be heat treated to a higher strength or toughness. Grade 5 is used in aircraft components such as landing gear, wing spars, and compressor blades. Its corrosion resistance is generally comparable to Grade 2 and it is often used in corrosion service where higher strength is required, particularly in shafts, high strength bolting, and keys. 
The weld deposit is ductile and offers excellent corrosion resistance in oxidizing environments. The unique combination of mechanical strenght and corrosion resistance makes the alloy a prefered choice in many applications to prefend or solve problems. The wire is cleaned in a very special way to obtain porosity free and a ductile weld deposit.
