Soft temper aluminum foil 8011
Soft temper aluminum foil 8011 is a widely used material in various industries due to its excellent flexibility, corrosion resistance, and superb barrier properties.
What is Soft Temper Aluminum Foil 8011?
Aluminum alloy 8011 is a widely used alloy, primarily thanks to its excellent corrosion resistance, moderate strength, and superior formability. When processed into soft temper (commonly designated as O temper), this foil exhibits a delicate balance of flexibility and strength, making it an ideal choice for many packaging and industrial applications.
"Soft temper" means the aluminum foil is annealed to derived minimal hardness, improving ductility and enabling it to be easily shaped or crumpled without cracking — a critical asset for applications requiring bending or folding.
Functions of 8011 Soft Temper Aluminum Foil
- Barrier protection: Its dense aluminum oxide layer blocks moisture, oxygen, light, odors, and bacteria, preserving product freshness.
- Flexible sealant: The soft temperization grants ideal malleability for airtight seals in packaging.
- Thermal insulation: Beat heat conductivity to maintain temperatures in packaging.
- Corrosion resistance: Resists deterioration in most atmospheres including various chemical environments.
- Taste & safety: Does not impart odor or taste, crucial in food and pharma usage.
- Recyclability: Illuminated its eco-friendly appeal, as aluminum foil is 100% recyclable.
Common Applications
Thanks to its properties, Aluminum 8011 Soft Temper foil is used extensively in sectors such as:
| Application Area | Description |
|---|---|
| Food packaging | Wrapping snacks, baked goods, fresh produce to extend shelf life. Up to thin warning barriers in polyethylene/aluminum laminate. |
| Household foil | Kitchen use for storage and cooking due to softness and strength. |
| Pharmaceutical packaging | Blister packs and foil for sealing medicines securely. |
| Cosmetic containers | Covers tins and lids requiring shaping with delicate foiling. |
| Electrical memos | Barrier in capacitors or insulation layers. |
| Industrial insulation | Heat reflectors or covering pipes and machinery for thermal insulation. |
Chemical Composition
The superior corrosion resistance of Alloy 8011 derives from its exact elemental composition which ensures its renowned durability and formability without sacrificing strength. Below is the typical chemical breakdown according to standards such as ASTM B479.
| Element | Percentage Content (wt%) |
|---|---|
| Aluminum | Balance (minimum 97.0%) |
| Iron (Fe) | 0.95 – 1.5% |
| Silicon (Si) | 0.20 – 0.80% |
| Copper (Cu) | ≤ 0.05% |
| Manganese (Mn) | 0.10 – 0.50% |
| Zinc (Zn) | ≤ 0.10% |
| Titanium (Ti) | ≤ 0.03% |
| Others (each) | ≤ 0.03% |
| Others (total) | ≤ 0.10% |
Tempering Conditions & Definitions
Soft temper aluminum discussed here generally conforms to the O temper as per international standards:
| Designation | Description | Tensile Strength (MPa) | Elongation (%) |
|---|---|---|---|
| O (Soft) | Annealed, minimal hardness | 35–55 | Typically ≥ 28 |
| H14 (Half Hard) | Slight strain hardening (for comparison) | 95–115 | ~3–6 |
The soft temper aluminum 8011 remains highly ductile and easy to manipulate using standard mechanical processing methods due to annealing (normally at ~350–415°C).
