8021 aluminium foil Features

8021 aluminum foil has good opacity and strong moisture proof & blocking capacity, and it doesn’t have any smell.

8021 aluminum foil is inexpensive, 耐久性のある, non-toxic and oil resistant.

8021 aluminium foil resists chemical erosion and provides excellent electrical and non-magnetic shielding.

Cold formed foil can absolutely resist steam and oxygen, with good aroma barrier performance.

Aluminium foil alloy 8021 拡張性が良い, 良好な深絞り性能, 良好な電解質腐食耐性, high heat seal strength, 等.

Typical application of 8021 アルミホイル

なぜなら 8021 aluminium foil is non-toxic, tasteless and food-grade safe, it often appears in food packaging, 医薬品包装およびその他の分野;

Battery jacket is also one of the typical applications of 8021 アルミホイル;

8011 対 8021 アルミホイル

1. 8011 aluminium foil contains Mn and Mg elements, しかし 8021 aluminium foil does not contain these two elements, so the strength and corrosion resistance of 8011 aluminum foil are higher than 8021 アルミホイル;

2. The strength of aluminium foil 8011 is high, but the corresponding elongation and puncture resistance under the same state are lower than 8021 アルミホイル. 8021 アルミホイルと 8079 aluminium foil are mostly used for blister aluminium and tropical aluminium that require higher performance and elongation;

3. The use of aluminium foil 8011 is more extensive, and can be used in many fields such as pharmaceutical packaging, 食品包装, お弁当の材料, テープホイル, ケーブルフォイル, milk cap material, ボトルキャップの素材, 等, その間 8021 aluminium foil is relatively expensive and is mostly used for requirements Relatively high lithium battery soft-wrapped aluminium-plastic film and blister drug packaging;

8021 aluminium foil production process

aluminium foil is a kind of rolled aluminium material. aluminium foil is mainly for thickness. In the industry, aluminium products with a thickness of less than 0.2mm are usually called aluminium foil.

The aluminium foil processing process is an aluminium product with the most processing procedures, the smallest thickness and the most difficult in the aluminium processing industry.

• 1. Melt aluminium into liquid (please refer to the アルミニウムの融点) and cast it into aluminium ingots. This process is called melting and casting;
• 2. Hot rolling – rolling above the recrystallization temperature;
• 3. Intermediate annealing – the behavior of inter-process annealing to eliminate the deformation strengthening effect of the workpiece, improve plasticity, and facilitate the implementation of subsequent processes;
• 4. Cold rolling – cold rolling is rolling below the recrystallization temperature;
• 5. Winding – store the finished aluminum foil in the form of coils;
