2XXX:Aluminum Copper Filler Alloys

The only 2XXX filler alloy readily available is 2319. This alloy contains copper (Cu), manganese (Mn), and titanium (Ti), and it was designed as a matching filler metal for the 2219 alloy. It is also used quite successfully for welding aluminum armor alloy 2519. This heat-treatable alloy responds to postweld heat treatment, resulting in increased strength. Other than that, it really has no other application.
