Core Properties of 8011 Aluminum Alloy
8011 is a non-heat-treatable aluminum alloy primarily composed of aluminum, iron, and silicon. Its chemical composition (Fe: 0.6-1.0%, Si: 0.5-0.9%) gives it a balanced set of properties that make it highly versatile for both industrial and consumer applications. Here are the key characteristics that define 8011 aluminum:
Exceptional Formability: 8011 aluminum is highly malleable, allowing for easy bending, stamping, rolling, and deep drawing. This makes it ideal for producing complex shapes and thin-walled components without cracking or material failure.
Good Weldability & Brazability: It can be easily welded using common methods such as MIG, TIG, and resistance welding, as well as brazed, enabling seamless assembly of components. Welds maintain good strength and corrosion resistance, ensuring structural integrity.
Reliable Corrosion Resistance: 8011 offers natural resistance to atmospheric corrosion and mild chemical environments. It performs well in both indoor and outdoor applications, with optional surface treatments further enhancing its durability in harsh conditions.
Lightweight & Cost-Effective: With a density of 2.71g/cm³, 8011 is lightweight, reducing overall product weight and transportation costs. As a non-heat-treatable alloy, it also offers cost advantages over heat-treatable grades, making it suitable for large-scale production.
Excellent Surface Finish: 8011 aluminum can be processed to achieve a smooth, uniform surface, which is ideal for applications requiring aesthetic appeal or a good base for painting, printing, or coating.
Food-Safe & Non-Toxic: 8011 is compliant with food contact regulations, making it a safe choice for packaging applications such as foil containers, beverage caps, and food wrapping materials.
A Deep Dive into 8011 Aluminum Tempers: O, H12, H14, H16, H18, H22
The performance of 8011 aluminum is largely determined by its temper, which is achieved through cold working (H tempers) or annealing (O temper). Each temper offers a unique balance of strength and ductility, making it suitable for specific applications. Here's a detailed breakdown of each available temper:
1. 8011 O Temper (Fully Annealed)
O temper is achieved by fully annealing the alloy, which softens it to the maximum extent. This temper prioritizes ductility and formability over strength, making it ideal for complex fabrication processes.
Key Properties: Tensile strength: 75-110 MPa; Yield strength: ≤35 MPa; Elongation: ≥35%.
Notable Traits: Ultra-formable, easy to bend and deep draw. No residual stress, ensuring dimensional stability during fabrication.
Ideal Applications: Deep-drawn components (e.g., cans, containers), complex stamped parts, food packaging foil, and applications requiring extensive shaping before final assembly.
2. 8011 H12 Temper (Strain Hardened, Low Strength)
H12 temper is produced by partial cold working without annealing. It offers low to moderate strength while maintaining good formability, striking a balance for applications that need more rigidity than O temper but still require some shaping.
Key Properties: Tensile strength: 110-150 MPa; Yield strength: 90-130 MPa; Elongation: ≥15%.
Notable Traits: Balanced formability and strength. Suitable for applications requiring light to moderate load-bearing capacity.
Ideal Applications: Automotive interior panels, decorative trim, lightweight structural brackets, and packaging components that need slight rigidity.
3. 8011 H14 Temper (Strain Hardened, Medium-Low Strength)
H14 temper involves more cold working than H12, resulting in higher strength while retaining acceptable formability. It's a popular choice for general-purpose applications that require a step up in rigidity from H12.
Key Properties: Tensile strength: 130-170 MPa; Yield strength: 110-150 MPa; Elongation: ≥10%.
Notable Traits: Versatile balance of strength and formability. Easy to cut, bend, and weld without significant loss of performance.
Ideal Applications: HVAC ducting, roofing flashing, electrical enclosures, lightweight furniture components, and beverage can ends.
4. 8011 H16 Temper (Strain Hardened, Medium Strength)
H16 temper is achieved through increased cold working, offering higher strength than H14. It's designed for applications that require moderate load-bearing capacity and good dimensional stability.
Key Properties: Tensile strength: 150-190 MPa; Yield strength: 130-170 MPa; Elongation: ≥8%.
Notable Traits: Good rigidity and resistance to deformation. Maintains weldability and can be formed into simple shapes.
Ideal Applications: Automotive exterior trim, trailer panels, storage tank components, tool boxes, and architectural cladding for low-load areas.
5. 8011 H18 Temper (Strain Hardened, High Strength)
H18 temper is the highest strength cold-worked temper for 8011 aluminum, produced by maximum cold working without annealing. It prioritizes strength and rigidity, with minimal formability.
Key Properties: Tensile strength: ≥180 MPa; Yield strength: ≥160 MPa; Elongation: ≥5%.
Notable Traits: Excellent rigidity and load-bearing capacity. Best for applications that require minimal shaping after fabrication.
Ideal Applications: High-strength packaging (e.g., aerosol cans), structural components for lightweight machinery, ladder rungs, and automotive heat shields.
6. 8011 H22 Temper (Strain Hardened & Partially Annealed)
H22 temper combines cold working with partial annealing, striking a balance between strength and ductility that's similar to H12 but with improved dimensional stability. The partial annealing reduces residual stress from cold working.
Key Properties: Tensile strength: 100-140 MPa; Yield strength: 80-120 MPa; Elongation: ≥18%.
Notable Traits: Better ductility than H12 with similar strength. Reduced risk of warping during fabrication, ideal for precision components.
Ideal Applications: Precision stamped parts, electrical connectors, decorative panels requiring fine detailing, and automotive components with tight dimensional tolerances.

Fabrication & Usage Tips for 8011 Aluminum Plates & Sheets
To maximize the performance of 8011 aluminum in your projects, here are practical tips based on our experience supporting manufacturers and contractors worldwide:
Temper Selection: Match the temper to your fabrication process and end-use: O temper for complex forming, H12-H22 for balanced strength/formability, and H18 for high-strength, minimal-shaping applications. Consult our technical team if you're unsure which temper fits your needs.
Cutting & Machining: Use sharp carbide tools or shears for cutting 8011 aluminum. For machining, maintain moderate cutting speeds and use coolant to prevent heat buildup, which can soften the material. Avoid excessive tool pressure to prevent work hardening.
Welding Guidelines: Use ER4043 filler metal for MIG/TIG welding to ensure strong, corrosion-resistant welds. Clean the surface thoroughly before welding to remove oxide, oil, or dirt. Keep heat input low to minimize the heat-affected zone (HAZ) and maintain material properties.
Forming Best Practices: For O temper, take advantage of its ultra-formability for deep drawing and complex bends. For H tempers, avoid overworking the material (excessive bending or rolling) to prevent cracking. Use lubricants during forming to reduce friction and improve surface finish.
Surface Treatment Options: Enhance corrosion resistance or aesthetics with surface treatments such as anodization, powder coating, or printing. 8011's smooth surface provides an excellent base for these treatments. Complete surface treatments after fabrication to avoid damaging the finish.
Storage & Handling: Store 8011 aluminum plates and sheets flat in a dry, covered area to prevent moisture buildup and corrosion. Keep the protective film on until final fabrication to avoid scratches. Handle with clean, lint-free gloves to avoid oil or dirt transfer, which can affect weld quality and surface finish.
