EN AW-2024 (AlCu4Mg1) is the same material your supplier may list as UNS A92024 or JIS A2024. This page maps the designations across standards and gives the ISO N-group machining starting point, brand-neutral.
| System | Designation |
|---|---|
| EN (EU) | EN AW-2024 (AlCu4Mg1) |
| Werkstoffnummer | 3.1355 |
| AISI / ASTM / UNS (US) | UNS A92024 |
| JIS (Japan) | A2024 |
Compiled from the public standard designation systems (EN 10027, SAE/AISI, ASTM, UNS, JIS). Entries marked “nearest” are the closest commonly-cited counterpart, not a drop-in equivalent. Always verify against the material certificate.
Strong, slightly abrasive aerospace alloy that machines beautifully in T3/T4 temper: excellent chips, high speeds. Uncoated sharp carbide or PCD, and clamp for the distortion, not the forces.
| ISO group | Starting Vc (coated carbide, turning) | Feed fn |
|---|---|---|
| N N · Non-ferrous | 300–1200+ m/min · 985–3940+ sfm | 0.05–0.3 mm/rev · .002–.012 ipr |

EN AW-2024 (AlCu4Mg1) (Werkstoffnummer 3.1355) corresponds to UNS A92024. In JIS terms the counterpart is A2024.
It is an ISO N-group material, so the starting window is 300–1200+ m/min · 985–3940+ sfm at 0.05–0.3 mm/rev · .002–.012 ipr for coated-carbide turning, adjusted for condition and operation. For a grounded, brand-neutral pick — grade, geometry and cutting data across 13 brands — ask the advisor.
They designate the same composition under different systems, but the drawing standard governs: certificates, tolerances and delivery-condition requirements differ between standards even for equivalent chemistry. Substitute only with the certificate in hand.
Knowing the material is half the job; picking the grade and cutting data for the operation is the other half. That is what the advisor does, grounded in catalog data and honest when there is no verified match.
