Difference between alloy 8011 aluminum foil and 8021 aluminum foil

With the development and progress of society, people's demand for the performance of required products is becoming more and more strict, which forces manufacturers to choose the strict requirements of production raw materials. The traditional metal materials have gradually failed to meet the needs of manufacturing high-performance products. Environmental protection is a hot topic nowadays. Aluminum foil, as an environmentally friendly, non-toxic and excellent material, conforms to the trend of the times and is widely used. As a new favorite of the times, alloy 8011 aluminum foil is widely used in drug packaging, food packaging, cable foil, milk capping material, sealing foil and other fields. The 8011 aluminum foil produced by us has clean surface, uniform color, no spots and flatness. At the same time, it also has excellent moisture-proof performance, shading and extremely high barrier ability, strong mechanical performance, high blasting resistance, puncture resistance and tear resistance. Non toxic, tasteless and hygienic. Aluminum foil after compounding, printing and gluing is widely used as packaging material. 8011 aluminum foil with thickness of 0.018-0.5mm can be processed, which can be customized according to customer requirements.

alloy 8011 aluminum foil

8011 aluminum foil and 8021 aluminum foil belong to 8-series aluminum alloy, but what is the difference between the two kinds of aluminum foil?

8011 aluminum foil introduction

8011 is a series of aluminum plates, belonging to 8 ××× Series alloy aluminum plate is added with Al Fe Si element, which has higher alloy properties than 1% of the total alloy elements. 8011 is commonly used as aluminum foil. Its performance is better than pure aluminum foil. It is widely used in aluminum foil, and aluminum plate is not commonly used.

8011 aluminum foil chemical composition:

8011 aluminum foil chemical composition (mass fraction) /% brand Si, Cr, Cu, Mn, Fe, Zn, Mg, Ti, others, Al, single, total, 8011, 0.5 ~ 0.9, ≤ 0.05, ≤ 0.10, ≤ 0.20, 0.6 ~ 1.0, ≤ 0.10, 0.05, ≤ 0.08, 0.05, 0.15

8021 aluminum foil introduction

The thickness range of 8021 aluminum foil production is 0.018mm-0.2mm, and the width can be controlled at 100-1650mm according to customer requirements. 8021 aluminum foil is the main product of food packaging and battery soft packaging aluminum foil. 8021 aluminum foil has excellent moisture resistance, light shielding and high barrier ability. Non toxic, tasteless, safe and hygienic. Aluminum foil after compounding, printing and gluing is widely used as packaging material.

Chemical composition of 8021 aluminum foil

8021 aluminum foil chemical composition (mass fraction) /% brand, Si, Cr, Cu, Mn, Zn, Mg, V, Ti, others, Al, single, total, 8021, ≤ 0.15, -, ≤ 0.05 -, 1.2 ~ 1.7 -, 0.05, 0.15, allowance

Difference between 8011 aluminum foil and 8021 aluminum foil:

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

2. Aluminum foil 8011 has high strength, but its elongation and puncture resistance under the same state are lower than 8021 aluminum foil. Therefore, in drug packaging, the aluminum foil coating on the back of drug capsule plate is mostly 8021 aluminum foil, while the Blister aluminum and tropical aluminum with higher requirements for sealing and elongation are mostly 8021 aluminum foil and 8079 aluminum foil;

3. Aluminum foil 8011 is more widely used and can be used in many fields such as drug packaging, food packaging, lunch box materials, tape foil, cable foil, milk capping materials, bottle capping materials, etc. while 8021 aluminum foil is relatively expensive and is mostly used in the packaging of lithium battery soft wrapped aluminum plastic film and blister drugs with relatively high requirements.
