8021 aluminum foil is a common alloy in 8000 series aluminum alloys. Common aluminum foils in 8000 series aluminum alloys include 8011 Aluminum Foil and 8079. We provide customized services for width and thickness. Customers can choose different alloys, tempering states, and thicknesses according to their needs. and width;
|Cupping test value (mm)||Note|
8021 aluminum foil has good opacity and strong moisture proof & blocking capacity, and it doesn’t have any smell.
8021 aluminum foil is inexpensive, durable, 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 has good extensibility, good deep drawing performance, good electrolyte corrosion resistance, high heat seal strength, etc.
Because 8021 aluminium foil is non-toxic, tasteless and food-grade safe, it often appears in food packaging, pharmaceutical packaging and other fields;
Battery jacket is also one of the typical applications of 8021 aluminium foil;
|8021 Battery Film Foil||Bare,Mill Finish||O /H*2 /H*4||0.035-0.055||100-1600||Coil|
|8021 Pharmaceutical Foil||H14 /H18||0.018-0.2||100-1600||Coil|
|8021 Packaging Foil||O /H22 /H24||0.018-0.2||100-1600||Coil|
1. 8011 aluminium foil contains Mn and Mg elements, but 8021 aluminium foil does not contain these two elements, so the strength and corrosion resistance of 8011 aluminum foil are higher than 8021 aluminium foil;
2. The strength of aluminium foil 8011 is high, but the corresponding elongation and puncture resistance under the same state are lower than 8021 aluminium foil. 8021 aluminum foil and 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, food packaging, lunch box materials, tape foil, cable foil, milk cap material, bottle cap material, etc., while 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;
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.
Common aluminium disc circle for lamps are 1050-O, 1060-O, 1100-O, etc., because the lampshade is obtained by stamping aluminum discs, and the O-state aluminum discs have better ductility and are more suitable for stamping treatment;
We use the pure aluminum ingots to manufacture 5mm aluminum sheets. They come in various widths and tempers. They are not only suitable for marine grade, but also for automobile manufacturing, pressure vessels, including water tanks, oil tanks, and the maximum width we can produce is 3000mm.
Brushed aluminum plate is a flat piece of aluminum material that has been treated with a brushing process to produce a uniform, unidirectional texture on its surface.

Anodized aluminum sheet is an aluminum sheet placed in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as an anode, and electrolysis is performed under specific conditions and the action of external current.
5005 aluminum sheet is a medium-strength aluminum alloy plate, which can reach medium and high strength by cold working, and it has good formability
