Working with A1N00-H12
Is A1N00 easy to machine?
Very soft and gummy — use polished high-rake carbide, high surface speed, sharp tools and generous lubricant to avoid built-up edge; hard tempers (H18) chip better than O.
Can A1N00 be welded?
Excellent with GTAW/GMAW using ER1100 or ER4043 filler; resistance welding and brazing are also routine, but the weld softens to near-O strength in the HAZ.
Can A1N00 be formed, bent or molded?
Outstanding cold formability in O/H22 — deep draws, spinning, and rolling to sub-10 µm foil; intermediate anneals restore ductility in hard tempers.
What surface finishes work on A1N00?
Takes clear/bright anodize, chemical conversion coating, lacquer and printing well; the anodic layer stays thin and soft, so use it for appearance and corrosion rather than wear.

A1N00-H12 — frequently asked
What is A1N00-H12 used for?
A1N00-H12 is typically used for electrolytic capacitor foil, high-purity electrical foil, etched anode and cathode foil stock, thin-gauge conductor strip, foil laminates and shielding and reflective foil sheet. In short: JIS capacitor-foil purity grade; near-maximum 1000-series formability; uniform etching characteristics.
What is the yield strength of A1N00-H12?
A1N00-H12 has a typical yield strength of 100 MPa (14.5 ksi) and a tensile strength of 110 MPa (16 ksi) — weaker than 84% of aluminum grades. Strength varies by condition: see the 9 listed tempers.
Is A1N00-H12 easy to machine?
Not especially — machinability is rated poor (27/100, worse than 95% of aluminum grades). Very soft and gummy — use polished high-rake carbide, high surface speed, sharp tools and generous lubricant to avoid built-up edge; hard tempers (H18) chip better than O.
Can A1N00-H12 be welded?
Yes — weldability is rated excellent (92/100). Excellent with GTAW/GMAW using ER1100 or ER4043 filler; resistance welding and brazing are also routine, but the weld softens to near-O strength in the HAZ.
What surface finishes work on A1N00-H12?

Can A1N00-H12 be formed, bent or molded?
Outstanding cold formability in O/H22 — deep draws, spinning, and rolling to sub-10 µm foil; intermediate anneals restore ductility in hard tempers.
What is the maximum service temperature of A1N00-H12?
A1N00-H12 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.
What is the difference between A1N00-O and A1N00-H18?
O is the default condition — softest, most formable condition — deep drawing, foil converting and any application needing maximum ductility. H18: maximum cold-worked strength; the standard temper for hard foil and capacitor/packaging foil stock. Yield strength is 35 MPa in O versus 150 MPa in H18.
