Titanium Grade 5 welding - properties, applications and technical data
Titanium Grade 5 (GR5, Ti-6Al-4V, UNS R56400, W.Nr. 3.7165, ERTi-5) is a high-strength filler metal for welding titanium alloys of similar composition. The material is used in applications where low weight, high strength, good corrosion resistance and reliable welds are essential.
This welding material is particularly suitable for the aerospace industry, medical technology, marine equipment, motorsports and other high-performance structures where strength to weight ratio is an important requirement.
Properties of Titanium Grade 5
Titanium Grade 5 is an alpha-beta titanium alloy with aluminum and vanadium as alloying elements. The material combines high mechanical strength with low weight, good fatigue strength and good corrosion resistance.
As a welding material, Titanium Grade 5 provides strong and stable welded joints, but requires careful shielding gas and a controlled welding environment to avoid the uptake of oxygen, nitrogen and hydrogen.
