ERTi-5 (6Al-4V)
Washington Alloy ERTi-5 commonly called “6-4”is a TIG, MIG, and submerged arc fillermetal use for welding alloyed Titanium with 6% & Aluminum 4%.
This grade is commonin the Titanium fillers due to its relatively low cost and good availability. With its high tensile strengths and good weld ability it can be heat treated to exhibits a higher fatigue, toughness found in petro chemical, aircrafts components, turbine parts and blades. Its corrosion resistance is generally compared to Grade 2 but yield a higher strength.
