Both 8011 and 8021 are aluminum alloys for pharmaceutical packaging, which are specially used to produce aluminum foil for pharmaceutical blister packaging. These aluminum foils are used to package tablets and capsules to protect them from external elements such as moisture, light and pollution. Although the 8011 and 8021 are similar in purpose, there are some differences in characteristics between them.

8011 8021 alloy composition:

8011: This is an alloy with aluminum and iron as the main elements. It is often referred to as a “pure” aluminum alloy because it contains a high proportion of aluminum with small amounts of other elements.
8021: This alloy contains aluminum, iron and slightly higher proportions of other elements such as silicon, titanium and other trace elements.

8011 8021 Mechanical properties:

8011: Due to the relatively pure 8011 aluminum composition, 8011 aluminum alloy has good formability, processability and flexibility.
8021: 8021 aluminum alloy also has good formability and processability, but its alloying elements may provide slightly different mechanical properties than 8011.

8011 8021 Applications:

Both 8011 and 8021 are commonly used in pharmaceutical blister packaging, but the specific choice between the two alloys may depend on factors such as pharmaceutical requirements, regulations and manufacturer preference.
