What is 8011-H14?
8011-H14 is 8011 in the H14 temper — the workhorse strip/foil-stock temper: enough strength for closures, fin stock and container foil while still forming well. 8011-H14 has a yield strength of 120 MPa (17.4 ksi) and a tensile strength of 145 MPa (21 ksi) — weaker than 77% of aluminum grades. Elongation at break is 4% and the elastic modulus is 69 GPa (10 Msi). 8011-H14 has a density of 2.71 g/cm³ (0.0979 lb/in³), heavier than 51% of aluminum grades. It melts at 620°C (1,148 °F).

Working with 8011-H14
Is 8011 easy to machine?
Very soft and gummy — use polished high-rake carbide, high speed, generous coolant/lubricant to avoid built-up edge; rarely machined since it ships as thin strip/foil.
Can 8011 be welded?
Not heat-treatable, so no HAZ softening problem beyond annealing; TIG/MIG with 1100 or 4043 filler works on strip, but typical foil gauges are joined by adhesive lamination or heat-seal lacquer instead.
Can 8011 be formed, bent or molded?
Excellent rollability to <10 µm foil and good drawing/curling in O–H24 tempers; harder H18/H19 tempers are chosen for push-through blister foil where controlled brittleness is wanted.
What surface finishes work on 8011?
Normally chromate/chrome-free conversion coated then lacquered, printed or PET/PE laminated; anodizing is possible but gives a dull grey film because of the Fe/Si intermetallics.

8011-H14 — frequently asked
What is 8011-H14 used for?
8011-H14 is typically used for pharmaceutical blister and push-through foil, food packaging foil, bottle cap and closure stock, air-conditioner fin stock, cable sheathing strip and container lidding foil. In short: foil and cap closure alloy.
What is the yield strength of 8011-H14?
8011-H14 has a typical yield strength of 120 MPa (17.4 ksi) and a tensile strength of 145 MPa (21 ksi) — weaker than 77% of aluminum grades. Strength varies by condition: see the 10 listed tempers.
Is 8011-H14 easy to machine?
Not especially — machinability is rated poor (30/100, worse than 91% of aluminum grades). Very soft and gummy — use polished high-rake carbide, high speed, generous coolant/lubricant to avoid built-up edge; rarely machined since it ships as thin strip/foil.
Can 8011-H14 be welded?
Yes — weldability is rated good (60/100). Not heat-treatable, so no HAZ softening problem beyond annealing; TIG/MIG with 1100 or 4043 filler works on strip, but typical foil gauges are joined by adhesive lamination or heat-seal lacquer instead.
What surface finishes work on 8011-H14?
Normally chromate/chrome-free conversion coated then lacquered, printed or PET/PE laminated; anodizing is possible but gives a dull grey film because of the Fe/Si intermetallics.
Can 8011-H14 be formed, bent or molded?
Excellent rollability to <10 µm foil and good drawing/curling in O–H24 tempers; harder H18/H19 tempers are chosen for push-through blister foil where controlled brittleness is wanted.
What is the maximum service temperature of 8011-H14?
8011-H14 is rated for continuous use to about 150°C (302 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
