Compare all 11 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Annealed | Maximum formability and highest thermal conductivity — pick for deep-drawn/embossed foil, container foil and laminate stock. | 40 | 95 | 25 | 23 HB | 55 % IACS |
Slightly strain hardened | Near-O softness with slightly higher strength from levelling/coiling; used where O flatness is hard to hold. | 50 | 100 | 22 | 26 HB | 54 % IACS |
Strain hardened and partially annealed, quarter hard | Soft, high-ductility back-annealed strip for formed fins and laminating foil. | 88 | 115 | 14 | 31 HB | 53.5 % IACS |
Strain hardened, quarter hard | Light cold work for mild stiffening while keeping high bend ductility. | 90 | 112 | 12 | 30 HB | 53 % IACS |
Strain hardened, half hard | Common half-hard strip temper balancing stiffness and roll-forming ability. | 110 | 128 | 8 | 38 HB | 52.5 % IACS |
H24Default Strain hardened and partially annealed, half hard | The standard heat-exchanger fin-stock condition: enough strength for fin-mill corrugating with retained ductility and good post-braze sag resistance. | 115 | 140 | 6 | 42 HB | 52 % IACS |
Strain hardened, three-quarter hard | Higher strength strip for stiffer fins and semi-rigid containers; bending radii must be generous. | 132 | 148 | 5 | 45 HB | 52 % IACS |
Strain hardened and partially annealed, three-quarter hard | Stronger fin stock for thin-gauge down-gauging where fin collapse resistance matters more than bend ductility. | 135 | 155 | 4 | 47 HB | 52.5 % IACS |
Strain hardened, full hard | Full-hard rolled condition for maximum as-rolled strength and flat, high-tension foil running. | 152 | 168 | 3 | 50 HB | 51.5 % IACS |
Strain hardened and partially annealed, full hard | Full-hard back-annealed strip; maximum strength with slightly better flatness/uniformity than H18. | 155 | 170 | 3 | 51 HB | 52 % IACS |
Strain hardened, extra hard | Heaviest cold reduction, used for very thin as-rolled foil where peak tensile is needed for web handling. | 170 | 185 | 2 | 55 HB | 51 % IACS |
What is 8014?
8014 is an Fe-Si-Cu bearing 8000-series aluminum (A98014, AlFeSiCu) rolled to strip and foil gauges in tempers from O and H111 through H19, including H22 to H28. It gives slightly higher strength than 8011 — 115 MPa yield, 140 MPa tensile and 42 HB in the default condition — while keeping the rollability needed for foil and fin stock, with 200 W/m·K thermal conductivity and 52 % IACS. Ductility falls to 1–3 % elongation in H18 and H19, machinability is poor (score 32), and joining is normally brazing or lamination rather than fusion welding. 8011 is the alternative when maximum formability outweighs strength. 8014 has a density of 2.73 g/cm³ (0.0986 lb/in³), heavier than 61% of aluminum grades. It melts at 645°C (1,193 °F). 8014 has a yield strength of 115 MPa (16.7 ksi) and a tensile strength of 140 MPa (20.3 ksi) — weaker than 79% of aluminum grades. Elongation at break is 6% and the elastic modulus is 69 GPa (10 Msi).

Working with 8014
Is 8014 easy to machine?
Rarely machined — very soft and gummy; if slitting/blanking, use sharp PCD or polished carbide, high rake, generous lubrication and tight die clearances to avoid burrs and web tearing.
Can 8014 be welded?
Resistance and TIG/MIG welding are feasible in thicker gauges with 4043/1100 filler, but in service the alloy is normally joined by controlled-atmosphere brazing (as fin against clad tube) or by adhesive lamination.
Can 8014 be formed, bent or molded?
Excellent cold rollability down to foil gauges; O/H22 for deep forming and embossing, H24/H26 for fin-mill corrugating — avoid tight bends in H18/H19 where elongation is only 1–3 %.

Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

What surface finishes work on 8014?
Usually supplied bare, degreased, or with hydrophilic/epoxy coil coatings; sulfuric anodizing is protective but grey and mottled owing to Fe-rich intermetallics, so chemical conversion or organic coating is preferred.

8014 — frequently asked
What is 8014 used for?
8014 is typically used for foil stock, fin stock and closures. In short: stronger than 8011 foil; fin and foil rolling stock; not a machining alloy.
What is the yield strength of 8014?
8014 has a typical yield strength of 115 MPa (16.7 ksi) and a tensile strength of 140 MPa (20.3 ksi) — weaker than 79% of aluminum grades. Strength varies by condition: see the 11 listed tempers.
Is 8014 easy to machine?
Not especially — machinability is rated poor (32/100, worse than 89% of aluminum grades). Rarely machined — very soft and gummy; if slitting/blanking, use sharp PCD or polished carbide, high rake, generous lubrication and tight die clearances to avoid burrs and web tearing.
Can 8014 be welded?
Yes — weldability is rated very good (70/100). Resistance and TIG/MIG welding are feasible in thicker gauges with 4043/1100 filler, but in service the alloy is normally joined by controlled-atmosphere brazing (as fin against clad tube) or by adhesive lamination.

Can 8014 be formed, bent or molded?
Excellent cold rollability down to foil gauges; O/H22 for deep forming and embossing, H24/H26 for fin-mill corrugating — avoid tight bends in H18/H19 where elongation is only 1–3 %.
What is the maximum service temperature of 8014?
8014 is rated for continuous use to about 150°C (302 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 8014-H24 and 8014-O?
H24 is the default condition — the standard heat-exchanger fin-stock condition: enough strength for fin-mill corrugating with retained ductility and good post-braze sag resistance. O: maximum formability and highest thermal conductivity — pick for deep-drawn/embossed foil, container foil and laminate stock. Yield strength is 115 MPa in H24 versus 40 MPa in O.
