| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Annealed | Default choice for deep drawing, spinning, chemical-vessel lining, foil and conductor work where maximum ductility and conductivity are needed. | 28 | 70 | 43 | 19 HB | 62 % IACS |
As fabricated | Cheapest hot-worked plate or extruded bus bar where only conductivity and corrosion matter, not guaranteed mechanicals. | 32 | 75 | 30 | 20 HB | 62 % IACS |
Slightly strain hardened | European-market near-soft temper for straightened/levelled sheet and extrusions that still need good forming. | 32 | 72 | 32 | 20 HB | 62 % IACS |
Strain hardened from hot working only | Hot-rolled plate and extruded bus bar/tube where a guaranteed minimum strength is required without cold rolling. | 35 | 78 | 25 | 21 HB | 62 % IACS |
Strain hardened, as-fabricated plate with light cold work | Commercially pure aluminium plate supplied hot-worked with a small amount of incidental cold work, giving strength just above the annealed condition with excellent formability and conductivity. | 40 | 85 | 22 | 23 HB | 61 % IACS |
Strain hardened and partially annealed, quarter hard | Same strength class as H12 but with better ductility and flatness after a partial anneal — good for formed strip. | 70 | 85 | 18 | 23 HB | 61.5 % IACS |
Strain hardened, quarter hard | Light cold work for slightly stiffer sheet that still bends and draws readily. | 76 | 83 | 16 | 23 HB | 61.5 % IACS |
Strain hardened and partially annealed, half hard | The most common Chinese-market 1060 sheet temper: H14-level strength with noticeably better bend performance. | 80 | 95 | 14 | 26 HB | 61.5 % IACS |
Strain hardened, half hard | General-purpose cold-rolled sheet: stiffer and flatter than O, still weldable and bendable over moderate radii. | 90 | 97 | 12 | 26 HB | 61.5 % IACS |
H26This page Strain hardened and partially annealed, three-quarter hard | H16 strength with improved ductility; used for roll-formed profiles and stiffer panel strip. | 95 | 110 | 10 | 30 HB | 61 % IACS |

Working with 1060-H26
Is 1060 easy to machine?
Very gummy — use polished high-rake carbide, high surface speed, generous flood coolant or MQL, and sharp tools to avoid built-up edge and torn finish.
Can 1060 be welded?
Excellent with TIG/MIG using 1100 or 1188 filler; resistance and friction-stir welding also fine, and welds are essentially as strong as annealed base metal (H-temper HAZ softens to O).
Can 1060 be formed, bent or molded?
Outstanding for deep drawing, spinning, stamping and roll forming in O/H22 tempers; bend radii can approach zero t in O, but H16–H19 need generous radii or interstage annealing.
What surface finishes work on 1060?
Takes bright dip, clear and hard anodize very well thanks to high purity; also easy to polish, brush, paint and powder coat, though the soft surface scratches readily.
