The difference between 8011 aluminum foil and 8021 aluminum foil

8011 is a series of aluminum plates, belonging to the 8 XXX series alloy aluminum plates. It is made by adding Al Fe Si elements, which have a relatively high advantage in the total alloy elements exceeding 1%. 8011 is commonly used to make aluminum foil, which has better performance than pure aluminum foil and is widely used in the field of aluminum foil.

The difference between 8011 aluminum foil and 8021 aluminum foil:

1. 8011 aluminum foil contains Mn and Mg elements, while 8021 aluminum foil does not contain these two elements, so the strength and corrosion resistance of 8011 aluminum foil are higher.

2. Aluminum foil 8011 has high strength, but its elongation and puncture resistance in the same state are lower than those of aluminum foil 8021. Therefore, in drug packaging, aluminum foil coatings are mostly made of aluminum foil 8021, while blister aluminum and tropical aluminum with higher requirements for sealing and elongation often use aluminum foil 8021 and aluminum foil 8079;

3. Aluminum foil 8011 has a wider range of applications, including pharmaceutical packaging, food packaging, meal box materials, tape foil, cable foil, milk cap materials, bottle cap materials, etc. Aluminum foil 8021 is relatively expensive and is mostly used in the packaging of lithium battery soft packaging aluminum-plastic film and blister drugs with relatively high requirements.
