Limitations of 8021 Aluminum Foil
Corrosion Resistance
8021 aluminum foil is not very resistant to corrosion, especially in acidic or alkaline environments. It may corrode over time, which can compromise its barrier properties.
Strength
8021 aluminum foil is not as strong as some other aluminum alloys, such as 8011 or 8079. This may limit its use in applications that require high tensile strength or puncture resistance.
