8011 aluminum foil and 8021 aluminum foil belong to 8 series aluminum alloy, but what is the difference between these two aluminum foils? China's large aluminum foil manufacturer - Henan Tendeli Metallurgical Co., Ltd. for your detailed answer.
8011 aluminum foil introduction:
8011 is a series of aluminum plates, belonging to the 8××× series alloy aluminum plate, which is added with Al-Fe-Si element. The alloy properties of more than 1% of the total alloy elements have corresponding advantages. 8011 is commonly used to make aluminum foil, its performance is better than pure aluminum foil, it is widely used in aluminum foil, aluminum sheet is not very common.
8011 aluminum foil and 8021 aluminum foil difference:
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 is higher than 8021 aluminum foil;
2, aluminum foil 8011 high strength, but the corresponding elongation and puncture resistance in the same state, lower than 8021 aluminum foil, so in the pharmaceutical packaging, the aluminum foil coating on the back of the drug capsule is mostly 8021 aluminum foil, and the seal The blister aluminum and tropical aluminum with higher requirements for elongation and elongation are made of 8021 aluminum foil and 8079 aluminum foil;
3, aluminum foil 8011 is more widely used, can be used in pharmaceutical packaging, food packaging, lunch box materials, tape foil, cable foil, milk cover material, bottle cap material and many other fields, while 8021 aluminum foil is relatively expensive, mostly used for requirements The relatively high lithium battery is packaged in a soft aluminum foil and blister pack.
