Working with 8006-H22
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 1000 series 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-H22 — frequently asked
What is 8006-H22 used for?
8006-H22 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-H22?
8006-H22 has a typical yield strength of 95 MPa (13.8 ksi) and a tensile strength of 125 MPa (18.1 ksi) — weaker than 86% of aluminum grades. Strength varies by condition: see the 11 listed tempers.
Is 8006-H22 easy to machine?
Not especially — machinability is rated poor (30/100, worse than 92% 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-H22 be welded?
Yes — weldability is rated very good (72/100). 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-H22?

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 1000 series at equal strength.
What is the maximum service temperature of 8006-H22?
8006-H22 is rated for continuous use to about 140°C (284 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
Can FabDigit make parts in 8006-H22?
Yes — 8006-H22 is available for sheet metal; every part is priced by an engineer rather than instantly. Upload a STEP file to get a price and a DFM check.
