What is 1060-O?
1060-O is 1060 in the O temper — default choice for deep drawing, spinning, chemical-vessel lining, foil and conductor work where maximum ductility and conductivity are needed. 1060-O has a yield strength of 28 MPa (4.06 ksi) and a tensile strength of 70 MPa (10.2 ksi) — weaker than 98% of aluminum grades. Elongation at break is 43% and the elastic modulus is 69 GPa (10 Msi). 1060-O has a density of 2.71 g/cm³ (0.0977 lb/in³), lighter than 54% of aluminum grades. It melts at 646°C (1,195 °F).

Working with 1060-O
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.
1060 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.

1060-O — frequently asked
What is 1060-O used for?
1060-O is typically used for bus bars and electrical connectors, chemical process equipment and liners, heat exchanger fin and tube, deep-drawn covers and vessels, foil, strip and shielding and reflector and bright trim sheet. In short: high purity; bus bar grade.
What is the yield strength of 1060-O?
1060-O has a typical yield strength of 28 MPa (4.06 ksi) and a tensile strength of 70 MPa (10.2 ksi) — weaker than 98% of aluminum grades. Strength varies by condition: see the 14 listed tempers.
Is 1060-O easy to machine?
Not especially — machinability is rated poor (25/100, worse than 96% of aluminum grades). 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-O be welded?
Yes — weldability is rated excellent (95/100). 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).
What surface finishes work on 1060-O?

What is the maximum service temperature of 1060-O?
1060-O is rated for continuous use to about 200°C (392 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
