| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Annealed | Pick for maximum ductility: deep drawing, spinning, hand forming, foil and fin stock. | 34 | 90 | 40 | 23 HB | 59 % IACS |
Strain hardened from hot working only | Pick for hot-rolled plate, extrusions and thick sections where only modest strength above annealed is needed. | 45 | 95 | 25 | 25 HB | 59 % IACS |
Strain hardened and partially annealed, quarter hard | Pick when H12 strength is wanted with more uniform ductility and less springback after forming. | 95 | 110 | 14 | 27 HB | 58 % IACS |
Strain hardened, quarter hard | Pick when annealed sheet is too limp but full forming ductility must be kept. | 105 | 110 | 12 | 28 HB | 57 % IACS |
Strain hardened and partially annealed, half hard | Pick for H14-level strength in deep-drawn or roll-formed parts where cracking risk must be lower. | 105 | 125 | 12 | 31 HB | 57 % IACS |
H14Default Strain hardened, half hard | Default stock condition: best all-round balance of stiffness in handling, bendability and price for sheet and coil. | 115 | 125 | 9 | 32 HB | 57 % IACS |
Strain hardened and partially annealed, three-quarter hard | Pick for higher-strength strip/coil that still needs moderate bending, e.g. shutters, fin and closure stock. | 130 | 145 | 8 | 36 HB | 57 % IACS |
Strain hardened, three-quarter hard | Pick for flat panels, shields and stampings needing more stiffness with only mild bending. | 140 | 145 | 6 | 38 HB | 57 % IACS |
Strain hardened, full hard | Pick for maximum strength/hardness in pure aluminium — flat strip, foil stock, blanking parts with little forming. | 150 | 165 | 5 | 44 HB | 57 % IACS |
What is 1100A?
1100A is the European variant of 1100, a commercially pure aluminum with about 0.12% copper (Al99.0Cu) in the EN 573 1000-series family, strengthened by cold work only. It is used interchangeably with 1100 for general sheet-metal work, kitchenware and chemical service, offering 222 W/m·K thermal conductivity, 57% IACS electrical conductivity and formability and weldability scores of 80 and 95; forms are sheet, strip, plate and tube in O through H26. In the default temper it reaches 115 MPa yield and 125 MPa tensile at 32 HB with 9% elongation, and it is not heat treatable, with service limited to about 150 °C. Choose 3003 when a manganese-bearing grade with higher strength is needed. 1100A has a density of 2.71 g/cm³ (0.0979 lb/in³), heavier than 51% of aluminum grades. It melts at 643°C (1,189 °F). 1100A has a yield strength of 115 MPa (16.7 ksi) and a tensile strength of 125 MPa (18.1 ksi) — weaker than 79% of aluminum grades. Elongation at break is 9% and the elastic modulus is 69 GPa (10 Msi).

Working with 1100A
Is 1100A easy to machine?
Very gummy in O/H12 — use polished high-rake carbide, high surface speed, sharp tools and flood lubricant; H18 chips break better and gives cleaner threads.
Can 1100A be welded?
Excellent with GTAW/GMAW using ER1100 (or ER4043 for crack-sensitive joints), resistance and brazing; weld metal reverts to near-annealed strength.
Can 1100A be formed, bent or molded?
Outstanding cold formability — deep draw, spin, roll-form and hem in O/H12; interanneal at 340–415 °C when heavy redrawing is needed.
1100A chemical composition (wt %)
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.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| Si+Fecombined limit per EN 573-3 / AA registration | ≤ 0.95 | |
| Cuintentional addition, raises strength slightly | 0.05 – 0.2 | 0.12 |
| Mn | ≤ 0.05 | |
| Zn | ≤ 0.1 | |
| Ticounted with 'others' in some registrations | ≤ 0.05 | |
| Others (each)total others 0.15 max; 1100A applies slightly tightened impurity control vs 1100 | ≤ 0.05 | |
| Al | ≥ 99 (balance) |
What surface finishes work on 1100A?
Takes bright and clear sulfuric anodizing, chemical conversion coating, paint and electroplating well; too soft for wear-resistant hard anodize, and mechanical polishing needs light pressure to avoid smearing.

1100A — frequently asked
What is 1100A used for?
1100A is typically used for kitchenware, chemical tanks and general sheet metal fabrication. In short: general-purpose pure aluminum; weldability score 95; slightly stronger than 1050A.

What is the maximum service temperature of 1100A?
1100A 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.

H14 is the default condition — default stock condition: best all-round balance of stiffness in handling, bendability and price for sheet and coil. O: pick for maximum ductility: deep drawing, spinning, hand forming, foil and fin stock. Yield strength is 115 MPa in H14 versus 34 MPa in O.
How much does 1100A cost?
1100A is a standard-cost aluminum ($$), cheaper than about 71% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
