8011 Aluminum Foil

8011 aluminum foil is made from high-purity aluminum, with an aluminum content of over 97%, featuring a dense metallic crystal structure. This tightly arranged crystal structure enhances the material's corrosion resistance, effectively protecting it from chemical corrosion in external environments. Its appearance is typically silver-white, with a smooth and delicate surface, boasting a reflectivity of up to 88%, making it capable of reflecting light and heat, suitable for insulation and protective purposes. The tensile strength of 8011 aluminum foil generally ranges from 125 to 165 MPa, with an elongation rate between 2% and 5%, demonstrating excellent flexibility and ductility. It can be processed into ultra-thin foil with thicknesses ranging from 0.006 mm to 0.2 mm while maintaining sufficient strength. With a thermal conductivity of 237 W/m·K, it can quickly transfer heat, and its melting point of 660°C grants it strong heat resistance, making it suitable for use in high-temperature conditions. 8011 aluminum foil also has excellent moisture resistance, with a water vapor transmission rate of nearly 0.01 g/m²/24h, serving as an effective barrier material that prevents the intrusion of moisture, air, and light, and is therefore widely used in food packaging, pharmaceutical packaging, and insulation materials.

Moisture Resistance
8011 aluminum foil has a dense metallic crystal structure that effectively prevents the penetration of water vapor, with a water vapor transmission rate close to 0.01 g/m²/24h. This means it almost completely blocks moisture, making it widely used in food packaging, such as for chocolate and candy, to prevent products from becoming damp and spoiled, thereby extending the shelf life of the food.

Workability
8011 aluminum foil has a tensile strength of 125-165 MPa and an elongation rate of 2%-5%. This combination of strength and flexibility allows it to be processed into ultra-thin sheets ranging from 0.006 mm to 0.2 mm, making it suitable for various packaging applications. It can form a strong protective seal while being resistant to tearing or breaking easily.

Thermal Insulation
With a reflectivity as high as 88%, 8011 aluminum foil efficiently reflects heat. This property allows it to be used in thermal insulation for buildings or automotive engines. The high reflectivity minimizes the amount of heat absorbed by the building, which means less heat enters the interior during warm weather. By reducing the need for cooling in summer, incorporating 8011 aluminum foil in building insulation directly contributes to a 15%-20% reduction in energy consumption, easing the burden on air conditioning and heating systems.

Aesthetic Appeal
8011 aluminum foil has a reflectivity of up to 88%, providing a bright metallic finish that enhances its visual appeal, particularly in premium packaging. The smooth and uniform surface quality, with a surface roughness (Ra) typically below 0.1 μm, allows for easy and high-quality printing, making it ideal for branding and product labeling. Additionally, 8011 aluminum foil has excellent anti-oxidation properties, with corrosion resistance ratings exceeding 95% in standard salt spray tests, ensuring that the foil maintains its appearance over extended periods without tarnishing or degrading in various environmental conditions.
