ERTi-5


Alloy Type:

ERTi- 5 (formerly 6AL/4V) is a TIG, MIG and submerged arc filler metal used for welding 6% aluminum-4% vanadium alloys.  The weld deposits of this alloy exhibit high fatigue strength, toughness, ductility and are heat treatable.  Widely used in the cryogenic, petrochemical and aircraft industry.  Aircraft uses would include the airframes; turbine engine parts such as the blades, discs, wheels and spacer rings.  Other applications would include industrial fans, pressure vessels, compressor blades and rocket motor cases.
