Aluminium copper alloy
AA 2319 (
UNS A92319
[1]: 448 ) is an
aluminium alloy principally containing
copper (5.8–6.8%) as an alloying element.
[2] 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 (in
arc welding electrodes) and up to 0.15% trace elements.
[2]
[3]: 3 The density of 2319 aluminium is 2840 kg/m3.
[3] This alloy was first registered in 1958, in the
United States.
[3]: 3
This alloy is typically used as an
arc welding electrode or filler material for use with
AA 2219 workpieces.
