Relevant Standard: AWS A5.16 ERTi-7; ASME SFA A5.16 ERTi-7; UNS R52400, W. NR. 3.7235

Description: 

ERTi-7, Titanium Grade 7 is similar to Grade 2, with the addition of the element palladium (Pd). The added element of palladium creates a strong corrosion resistance at a low density. ERTi-7 can be used to weld titanium base metals of similar composition such as 2, 16, and 26. This alloy is typically used in applications of valves, heat exchangers, piping and fittings.
Chemical Components(wt%)

Application Fields:
Grade 7 has better corrosion resistance than grade 2 due to the addition of 0.12-0.25% palladium, mechanical properties are similar to grade 2. The deposit is ductile and provides excellent corrosion resistance in oxidizing environments. The unique combination of mechanical strength and corrosion resistance makes the alloy a preferred choice in many applications to prevent or solve problems. The wire is cleaned in a very special way to provide a porous and ductile weld deposit.

Relevant Standard: AWS A5.16 ERTi-9; ASME SFA A5.16 ERTi-9

Description: 

This material is often referred to as “half 6-4” because the major components are roughly half that found in ERTi-5. Primary use, to date, has been in welding hydraulic tubing and fittings for aircraft. Has the ability to maintain strength at elevated temperatures. Titanium is a reactive metal that is sensitive to embrittlement by oxygen, nitrogen and hydrogen at temperatures above 500F. This can be provided by shielding the metal with high purity inert gas or in a chamber. Cleanliness of the joint is a major factorin producing porosity free welds. Protection of the wire at all times is required to assure cleanliness. Can be fusion welded to Zirconium, Tantalum, Nobium and Vanadium. Should not be fusion welded to Copper, Iron, Nickel, and Aluminum, as it will produce extremely brittle welds.
