QuAlCu6 Bobbin – Laser Welding Wire Aluminium AlCu6 / ER2319 – Aerospace, Age-Hardenable
QuAlCu6 is the AlCu wire for higher-strength aluminium components: EN ISO 18273 S Al 2319 (AlCu6MnZrTi) · AWS ER2319. The datasheet explicitly names the aerospace industry as its field of use.
It is an age-hardenable alloy — the strength comes not from welding but from the subsequent heat treatment. Copper (6.3 %) carries it, zirconium and titanium refine the grain. Important, and the datasheet says so explicitly: do not use on 5xxx aluminium alloys (AlMg) — copper and magnesium do not get along in the weld.
Recommended base materials
- AL 2219, AL 2014
- AlCu casting alloys
- Do not use on 5xxx aluminium alloys (AlMg) — datasheet
Typical applications
- Aerospace industry
- Higher-strength aluminium components
- AlCu castings
- Parts that are subsequently age hardened
Properties and advantages
- Age-hardenable — strength set after welding
- Cu 6.3 % with Zr and Ti for grain refinement
- Re 150 MPa · Rm 240 MPa · A 12 %
- Not for AlMg (5xxx)
