Compare all 10 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Annealed | Default choice for deep drawing, forming, fin/foil stock and cladding — maximum ductility and conductivity. | 28 | 80 | 38 | 20 HB | 61 % IACS |
As fabricated | Mill product with no mechanical property guarantee; pick for re-rolling or further working. | 35 | 85 | 30 | 22 HB | 61 % IACS |
Strain hardened and partially annealed, quarter hard | Stabilised quarter-hard temper giving H12 strength with better ductility and flatness. | 70 | 95 | 16 | 24 HB | 60 % IACS |
Strain hardened, quarter hard | Light cold work when slightly stiffer sheet is needed but forming must stay easy. | 75 | 95 | 12 | 25 HB | 60 % IACS |
Strain hardened and partially annealed, half hard | Half-hard strength with retained bend ductility — common for formed foil containers and fin stock. | 90 | 115 | 11 | 29 HB | 60 % IACS |
Strain hardened, half hard | General-purpose semi-rigid sheet/strip with moderate bending ability. | 100 | 115 | 8 | 30 HB | 60 % IACS |
Strain hardened and partially annealed, three-quarter hard | Stabilised three-quarter hard strip for shallow forming with better crack resistance than H16. | 110 | 130 | 7 | 32 HB | 60 % IACS |
Strain hardened, three-quarter hard | Higher stiffness strip for shallow forming and roll-formed profiles. | 120 | 130 | 5 | 33 HB | 60 % IACS |

Strain hardened, extra hard | Extra-hard thin foil/fin stock where tensile strength and gauge control matter more than ductility. | 155 | 165 | 2.5 | 40 HB | 59 % IACS |
What is 1230?
1230 is a commercially pure aluminium (min 99.30 % Al) wrought alloy used mainly as the cladding layer on Alclad plate/sheet and as household/industrial foil and fin stock. It is chosen for its high electrical/thermal conductivity, excellent formability and corrosion resistance, and its slightly anodic potential that sacrificially protects the clad core alloy. Its limits are very low strength (only strain-hardenable, no heat-treat response), poor machinability and rapid softening above ~150 °C. 1230 has a density of 2.7 g/cm³ (0.0975 lb/in³), lighter than 59% of aluminum grades. It melts at 646°C (1,195 °F). 1230 has a yield strength of 28 MPa (4.06 ksi) and a tensile strength of 80 MPa (11.6 ksi) — weaker than 98% of aluminum grades. Elongation at break is 38% and the elastic modulus is 69 GPa (10 Msi).

Physical3
1230 has a density of 2.7 g/cm³ (0.0975 lb/in³), lighter than 59% of aluminum grades. It melts at 646°C (1,195 °F).
Mechanical10
1230 has a yield strength of 28 MPa (4.06 ksi) and a tensile strength of 80 MPa (11.6 ksi) — weaker than 98% of aluminum grades. Elongation at break is 38% and the elastic modulus is 69 GPa (10 Msi).
Thermal6
1230 is rated for continuous service to 150°C (302 °F). It conducts heat at 231 W/m·K (133.5 BTU/hr·ft·°F), better than 97% of aluminum grades. Thermal expansion is 23.6 µm/m·K (13.1 µin/in·°F).

Chemical & Environmental3
Corrosion resistance is very good (82/100), better than 99% of aluminum grades.
Sustainability4
Producing a kilogram of 1230 takes about 205 MJ of energy and emits 12 kg of CO₂ — more than 76% of aluminum grades. Typical recycled content is 10%.
Manufacturability8
1230's machinability is poor (28/100, worse than 94% of aluminum grades); weldability excellent (92/100); formability excellent (97/100).

Working with 1230
Is 1230 easy to machine?
Very gummy — use sharp high-rake polished carbide tools, high speed, low feed pressure and flood lubricant; expect burrs and built-up edge.
Can 1230 be welded?
Excellent with GTAW/GMAW using 1100 or 1188 filler; autogenous welds are sound but weld zone anneals to O-temper strength.
Can 1230 be formed, bent or molded?
Outstanding cold formability in O/H2x tempers — deep drawing, roll forming and foil rolling to <10 µm; H18/H19 needs generous bend radii.

How much does 1230 cost?
1230 is a budget-cost aluminum ($), cheaper than about 99% 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.
