Compare all 7 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Annealed | Choose for maximum drawability — automotive inner panels, deep-drawn shells and stampings that need high uniform elongation. | 130 | 275 | 21 | 70 HB | 31 % IACS |
Slightly strain hardened | Standard European sheet condition for formed parts where light levelling/flattening strain is acceptable and O-temper stretcher strains must be reduced. | 150 | 290 | 19 | 75 HB | 31 % IACS |
Strain hardened and stabilized, full hard | Stabilized hard sheet for high-Mg parts that must keep dimensional and property stability (age-softening resistance) after forming. | 330 | 385 | 6 | 100 HB | 31 % IACS |
Strain hardened, full hard | Fully cold-worked (8/8 hard) Al-Mg4.5Mn0.4 sheet/strip with very high strength and low ductility, used for can end and tab stock. | 385 | 410 | 4 | 105 HB | 31 % IACS |
Strain hardened extra hard and lacquered/painted | H19-strength coil that is coil-coated on one or both faces; the standard supply condition for beverage-can ends and tabs going straight to the press. | 385 | 415 | 4 | 108 HB | 30 % IACS |
Strain hardened, extra hard | The high-strength can-end and tab stock condition — pick when maximum strength in thin gauge with adequate residual formability for scoring/curling is required. | 395 | 420 | 4 | 110 HB | 31 % IACS |
Strain hardened and stabilized, extra hard | Cold-worked to extra-hard level then low-temperature stabilized, giving the highest 5182 strip strength with stable properties for can end/tab stock. | 400 | 420 | 4 | 110 HB | 31 % IACS |
What is 5182?
5182 is a non-heat-treatable Al–Mg (≈4.5 % Mg, 0.35 % Mn) wrought alloy supplied almost exclusively as coil/sheet. Its very high work-hardening rate gives high strength with good formability, which is why it dominates beverage-can end and tab stock (H19/H48) and is used as high-formability automotive inner-panel sheet (O/H111). Limits are the sensitization risk of >3 % Mg alloys above roughly 65–80 °C (susceptibility to intergranular/stress-corrosion attack), pronounced stretcher-strain (Lüders) marking in the O temper, and no response to precipitation hardening. 5182 has a density of 2.65 g/cm³ (0.0957 lb/in³), lighter than 90% of aluminum grades. It melts at 577°C (1,071 °F). 5182 has a yield strength of 130 MPa (18.9 ksi) and a tensile strength of 275 MPa (39.9 ksi) — weaker than 73% of aluminum grades. Elongation at break is 21% and the elastic modulus is 70 GPa (10.2 Msi).

Working with 5182
Is 5182 easy to machine?
Soft and gummy in O/H111 — use sharp polished-flute carbide tools, high speed, generous rake and flood lubrication; H19/H48 chips break better but the alloy is normally blanked, not machined.
Can 5182 be welded?
Readily GTAW/GMAW/resistance and laser welded with 5356 or 5183 filler; no post-weld heat treatment needed but the weld zone reverts to near-O strength and high-Mg welds should stay below ~65 °C service.
Can 5182 be formed, bent or molded?
Outstanding stretch/deep-draw formability in O temper (high n-value); expect Lüders/stretcher-strain marks in O and use H111 or a temper roll pass for visible surfaces; H19/H48 is designed for high-speed shell pressing, scoring and curling only.

What surface finishes work on 5182?
Accepts clear/bright anodizing, conversion coating and coil lacquer well; degrease thoroughly since Mg-rich surface oxide forms fast, and pre-etch before painting for reliable adhesion.
