Aluminum Alloy, Welding Wire 6.3Cu 0.3Mn 0.18Zr 0.15Ti 0.10V (2319)
This specification covers an aluminum alloy in the form of welding wire. This wire has been used typically as filler metal for gas-metal-arc or gas-tungsten-arc welding of aluminum alloys of similar composition where the joint is capable of being heat treated to a strength level comparable to that of the parent metal, but usage is not limited to such applications.
