2319 aluminium alloy
AA 2319 is an aluminium alloy principally containing copper as an alloying element. It also contains ≤0.20% silicon, ≤0.30% iron, 0.20–0.40% manganese, ≤0.02% magnesium, ≤0.10% zinc, 0.10–0.20% titanium, 0.05–0.15% vanadium, 0.10–0.25% zirconium, ≤0.0003% beryllium and up to 0.15% trace elements. The density of 2319 aluminium is. This alloy was first registered in 1958, in the United States.
This alloy is typically used as an arc welding electrode or filler material for use with AA 2219 workpieces.
