Selection summary
Overview
8011 is a registered wrought aluminum alloy widely supplied as foil, but alloy identity alone does not define a packaging product. The order must add exact temper, thickness, width, surface side, pinhole and wettability criteria, tensile or burst requirements, cleanliness, food-contact or pharmaceutical compliance, winding, splices and packing.
This page separates standard-oriented limits from typical reference data. Purchase acceptance comes from the ordered specification and certified material test report.
Names and systems
Identity & standards
Similar designations across ASTM, EN, JIS, and other systems are not automatically interchangeable. Product form and ordered standard control chemistry, properties, dimensions, condition, and testing.
Reference chemistry
Composition
| Element | Reference range | Why it matters |
|---|---|---|
| Silicon | Registered 8011 range | Strength and rolling response |
| Iron | Registered 8011 range | Strength, grain structure and foil behavior |
| Aluminum | Remainder | Base metal and barrier substrate |
Concise grade-family reference only. Confirm every element limit against the current standard for the exact product ordered.
Condition matters
Reference properties
O, H18, H22 and other tempers cannot share one acceptance value.
Forming, lidding and flexible barrier uses need different targets.
Measure and report with the agreed method and sampling plan.
Environment first
Corrosion behavior
The natural oxide film supports general atmospheric stability, but acidic, alkaline, salty and dissimilar-metal contact requires package-system review.
Lacquer, laminate, printing ink and sealing layer compatibility can dominate real barrier life.
Temperature, concentration, deposits, crevices, stress, surface finish, cleaning, and fabrication quality can change service performance.
Service limits
Temperature & service
Sterilization, baking, freezing and heat sealing can change temper response, coating adhesion and laminate performance.
Delivery condition
Heat treatment & condition
8011 is commonly supplied in O or work-hardened H tempers selected for forming or converter performance.
Annealing cleanliness, oil removal and final temper are purchase-critical for wettability and bonding.
Process route
Fabrication
Double rolling can create one bright and one matte side; side orientation must be stated when appearance or coating requires it.
Slitting, printing, lacquering, laminating, embossing and forming each add separate acceptance criteria.
Magnetic response: Non-ferromagnetic.
Decision boundaries
Comparisons & substitution
8011 is included in ASTM B479 packaging-foil scope; 8021 selection more often relies on registered alloy identity and the ordered EN/ISO or customer foil specification.
1235, 8079 and other foil alloys differ in chemistry, rolling behavior and converter performance; do not substitute by thickness alone.
Where it is used
Applications
Ordering scope
Product forms & standards
Annealed foil under ASTM B479 when the alloy, temper and application fall within its scope.
Foil and thin strip ordered with ISO 7271 dimensional tolerances or the applicable EN/customer specification.
Decision support
Selection guidance
Choose this grade when
- A proven 8011 converter route provides the required forming, barrier, surface and compliance performance.
- The RFQ can define the final laminate or formed-package acceptance criteria.
Review another grade when
- Extreme deep drawing, pinhole control, battery, capacitor or highly regulated pharmaceutical service dominates.
- The buyer has specified only alloy and thickness without temper, surface, compliance or converter tests.
Before ordering
Procurement checklist
State 8011, exact temper, thickness, width, core, coil mass and winding direction.
State bright/matte side, pinhole, wettability, cleanliness, splice, edge and surface-defect limits.
State converter process, food/pharma declarations, coating or laminate, tests, packing and shelf-life protection.
