Aluminum 8011
AA 8011 · UNS A98011 · EN AW-8011, AW 8011
8011 is an 8000 series Al-Fe-Si alloy (EN AW-8011) that gains strength from fine Fe- and Si-bearing dispersoids; it is not heat-treatable, so strength comes only from cold work in the H tempers.
8011 tempers and conditions
8011 is supplied in 10 conditions, soft to hard.
Compare all 10 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Annealed | Pick for deep-drawn caps, soft household/lidding foil and maximum formability. | 40 | 95 | 25 | 24 HB | 48 % IACS |
Strain hardened and partially annealed, quarter hard | Back-annealed quarter-hard strip: better ductility and flatness than H12 at similar strength. | 90 | 125 | 10 | 34 HB | 46 % IACS |
Strain hardened, quarter hard | Light cold work for strip that still needs substantial bending/forming. | 95 | 120 | 7 | 35 HB | 46 % IACS |
Strain hardened and partially annealed, half hard | Common closure/fin-stock temper when deep drawing or curling is combined with mid strength. | 110 | 145 | 6 | 41 HB | 45 % IACS |
Strain hardened, half hard | The workhorse strip/foil-stock temper: enough strength for closures, fin stock and container foil while still forming well. | 120 | 145 | 4 | 42 HB | 45 % IACS |
Strain hardened and partially annealed, three-quarter hard | Higher strength with retained ductility for stiff but still formable strip. | 135 | 165 | 4 | 47 HB | 45 % IACS |
Strain hardened, three-quarter hard | Higher-strength cap and closure stock where only mild forming is required. | 145 | 165 | 3 | 48 HB | 45 % IACS |
Strain hardened and partially annealed, full hard | Near-maximum strength with slightly better ductility/flatness than H18. | 160 | 185 | 2.5 | 52 HB | 44 % IACS |
Strain hardened, full hard | Standard temper for pharmaceutical blister (push-through) foil and stiff strip — high strength, low elongation. | 165 | 185 | 2 | 53 HB | 44 % IACS |
Strain hardened, extra hard | Extra-hard thin foil/strip where maximum as-rolled strength and flatness are needed. | 185 | 205 | 1.5 | 57 HB | 44 % IACS |
What is 8011?
8011 is an 8000 series Al-Fe-Si alloy (EN AW-8011) that gains strength from fine Fe- and Si-bearing dispersoids; it is not heat-treatable, so strength comes only from cold work in the H tempers. It is the standard grade for pharmaceutical and food packaging foil, cap and closure stock, air-conditioner fin stock and cable sheathing strip, combining good formability, weldability/coatability and corrosion resistance. Limits are low strength, no response to heat treatment, poor machinability (it smears and sticks to the tool) and a dull grey anodized colour caused by the Fe/Si content. For heavier fin or strip work 3003 is the usual alternative. 8011 has a density of 2.71 g/cm³ (0.0979 lb/in³), heavier than 51% of aluminum grades. It melts at 620°C (1,148 °F). 8011 has a yield strength of 120 MPa (17.4 ksi) and a tensile strength of 145 MPa (21 ksi) — weaker than 77% of aluminum grades. Elongation at break is 4% and the elastic modulus is 69 GPa (10 Msi).

Working with 8011
Is 8011 easy to machine?
Very soft and gummy — use polished high-rake carbide, high speed, generous coolant/lubricant to avoid built-up edge; rarely machined since it ships as thin strip/foil.
Can 8011 be welded?
Not heat-treatable, so no HAZ softening problem beyond annealing; TIG/MIG with 1100 or 4043 filler works on strip, but typical foil gauges are joined by adhesive lamination or heat-seal lacquer instead.
Can 8011 be formed, bent or molded?
Excellent rollability to <10 µm foil and good drawing/curling in O–H24 tempers; harder H18/H19 tempers are chosen for push-through blister foil where controlled brittleness is wanted.
Manufacturability
The process limits FabDigit applies to 8011. Every 8011 part is priced by an engineer; design inside these and the quote comes back without a redesign loop.

What surface finishes work on 8011?
Normally chromate/chrome-free conversion coated then lacquered, printed or PET/PE laminated; anodizing is possible but gives a dull grey film because of the Fe/Si intermetallics.
Surface treatments FabDigit runs on aluminum parts — pick them in the quote configurator or call them out on the drawing. Each links to its datasheet in the surface-finish library (thickness, specs, call-out, material verdicts).
