8011 aluminum alloy coil is a versatile and widely used aluminum material known for its excellent corrosion resistance, high strength, and good formability. It belongs to the 8xxx series aluminum alloys, which are primarily used for packaging, household, and industrial applications.
8011 aluminum alloy coil is a popular material known for its excellent formability, weldability, and corrosion resistance. It's widely used in various industries due to its versatility and cost-effectiveness.
The primary alloying element in 8011 aluminum is iron (Fe). The typical composition includes:
Aluminum (Al): 97.0 - 99.0%
Iron (Fe): 0.5 - 1.0%
Silicon (Si): 0.6 - 1.0%
Copper (Cu): 0.1% max
Manganese (Mn): 0.2% max
Zinc (Zn): 0.1% max
Titanium (Ti): 0.08% max
Excellent Formability: 8011 aluminum alloy is highly formable, making it suitable for complex shapes and deep drawing processes. It can be easily bent, stamped, and drawn.
Good Weldability: It can be readily welded using common welding techniques like TIG, MIG, and resistance welding.
Good Corrosion Resistance: It exhibits good resistance to atmospheric corrosion and attack by many chemicals.
High Reflectivity: Aluminum in general has high reflectivity, making it useful in applications where heat or light reflection is important.
Low Density: Aluminum's low density makes it lightweight, a crucial factor in many applications.
Non-toxic: Aluminum is generally considered non-toxic, making it suitable for food packaging applications.
Recyclable: Aluminum is highly recyclable, making it an environmentally friendly material.
8011 aluminum alloy coils are available in various tempers, each with distinct mechanical properties:
O Temper (Annealed): The softest and most formable temper.
H22 Temper (Strain Hardened and Partially Annealed): Increased strength compared to the O temper with retained formability.
H24 Temper (Strain Hardened and Partially Annealed): Higher strength than H22, with reduced formability. A commonly used temper.
8011 aluminum alloy coil finds extensive use in a wide range of applications, including:
Food Packaging: Aluminum foil for household use, food containers, and packaging materials. Its non-toxicity and barrier properties make it ideal for preserving food.
Pharmaceutical Packaging: Blister packs for tablets and capsules. Provides excellent protection against moisture and light.
Industrial Packaging: Lidding foil for yogurt, cheese, and other dairy products.
Cable Wrapping: Shielding for cables and wires, providing protection and signal integrity.
Container Manufacturing: Used in the production of semi-rigid containers.
Fin Stock: Heat exchangers and air conditioners, utilizing its thermal conductivity.
Caps and Closures: Caps for bottles and other containers.
Laminations: Used as a layer in laminated materials to provide barrier properties, strength, or reflectivity.
Cost-Effective: Compared to other alloys, 8011 offers a good balance of properties at a reasonable cost.
Versatile: Its properties allow for a wide range of applications.
Sustainable: Recyclability reduces environmental impact.
Lightweight: Contributes to reduced weight in finished products.
Thickness: Select the appropriate thickness based on the required strength and application.
Temper: Choose the temper that provides the necessary balance of formability and strength.
