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.
