2319 Aluminum Alloy Plate

2319 aluminium alloy is an alloy principally containing copper (5.8–6.8%) 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 (in arc welding electrodes) and up to 0.15% trace elements. The density of 2319 aluminium is 2840 kg/m3. 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.

2319 aluminium alloy is a Aluminium Filler alloy which was developed for use with 2219 aluminium alloy, which is an alloy that is commonly used in high strength structural and aircraft applications. 2319 aluminium alloy is heat treatable and provides higher strength and better ductility than the 4xxx filler alloys when welding 2xxx alloys.

2319 aluminium alloy is widely used in high strength structural, aircraft and truck body applications where superior resistance, formability and/or electrical conductivity are required. Especially suitable for use where superior resistance to stress corrosion cracking and excellent elevated temperature properties are desired. The alloy is heat treatable and provides higher strength and better ductility than the 4XXX filler alloys when welding 2XXX alloys.
