Properties of the O condition, compared with the other 8006 tempers.
Pick for deep-drawn containers, formed lids and soft laminating foil needing maximum elongation.
What is 8006-O?
8006-O is 8006 in the O temper — pick for deep-drawn containers, formed lids and soft laminating foil needing maximum elongation. 8006-O has a yield strength of 45 MPa (6.53 ksi) and a tensile strength of 110 MPa (16 ksi) — weaker than 95% of aluminum grades. Elongation at break is 35% and the elastic modulus is 69 GPa (10 Msi). 8006-O has a density of 2.71 g/cm³ (0.0979 lb/in³), heavier than 51% of aluminum grades. It melts at 630°C (1,166 °F).

Working with 8006-O
Is 8006 easy to machine?
Rarely machined; if slit/blanked, use sharp carbide tooling, high rake and lubricant — the soft matrix with hard Fe-intermetallics burrs easily and abrades edges.
Can 8006 be welded?
Weldable by GTAW/GMAW with 1100 or 4043 filler and by resistance/ultrasonic methods; heat-affected zone reverts to O-temper strength, and foil gauges are normally sealed rather than welded.
Can 8006 be formed, bent or molded?
Excellent deep-draw and wall-ironing behaviour, especially in O/H22/H24; the fine Al-Fe-Mn dispersoids give higher elongation and pinhole resistance than 1xxx at equal strength.
What surface finishes work on 8006?
Takes chromate-free conversion coatings, lacquers and PET/PP laminations well; anodizing gives a dark grey non-decorative film, so painted or coated finishes are preferred.

8006-O — frequently asked
What is 8006-O used for?
8006-O is typically used for deep-drawn container and tray foil, lidding and sealing foil, heat exchanger fin stock, flexible packaging foil laminates, capacitor foil and clad brazing foil. In short: iron-rich foil base.
What is the yield strength of 8006-O?
8006-O has a typical yield strength of 45 MPa (6.53 ksi) and a tensile strength of 110 MPa (16 ksi) — weaker than 95% of aluminum grades. Strength varies by condition: see the 11 listed tempers.
Is 8006-O easy to machine?
Not especially — machinability is rated poor (25/100, worse than 96% of aluminum grades). Rarely machined; if slit/blanked, use sharp carbide tooling, high rake and lubricant — the soft matrix with hard Fe-intermetallics burrs easily and abrades edges.
Can 8006-O be welded?
Yes — weldability is rated very good (70/100). Weldable by GTAW/GMAW with 1100 or 4043 filler and by resistance/ultrasonic methods; heat-affected zone reverts to O-temper strength, and foil gauges are normally sealed rather than welded.
What surface finishes work on 8006-O?

Excellent deep-draw and wall-ironing behaviour, especially in O/H22/H24; the fine Al-Fe-Mn dispersoids give higher elongation and pinhole resistance than 1xxx at equal strength.
What is the maximum service temperature of 8006-O?
8006-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.
