Definition of aluminum foil material

What is aluminum foil material? O material de folha de alumínio é um material que é enrolado diretamente em folhas finas usando metal alumínio (placa de alumínio com uma certa espessura). A folha de alumínio tem características de textura macia, boa ductilidade, e brilho branco prateado. É amplamente utilizado em muitos campos. The following is a detailed introduction to aluminum foil material:

Detailed introduction to aluminum foil material

Aluminum foil thickness type

Aluminum foil material is soft and can be processed into different thicknesses as needed. Huawei Aluminum can produce specific thicknesses.

Aluminum foil materials are classified in thickness range

Tipo	Thickness Range	Application Areas
Light aluminum foil	0.005~0.02 mm	Suitable for packaging and disposable items, como embalagens de alimentos, embalagens farmacêuticas, etc..
Medium aluminum foil	0.02~0.06 mm	Suitable for cooking and baking, and can withstand certain temperature changes without being easily damaged.
Heavy aluminum foil	Above 0.06 milímetros	Mainly used for industrial purposes and special packaging, such as electronic product packaging, insulation and heat preservation materials, etc..

Aluminum foil materials are classified by thickness accuracy

Tipo	Thickness Range	Características
Thick Foil	0.1~0.2 mm	Relatively thick, with high strength and stability
Single Zero Foil	less than or equal to 0.1 milímetros, but greater than 0.01 milímetros.	The thickness is relatively accurate and suitable for occasions with certain requirements for thickness.
Double Zero Foil	less than 0.0075 milímetros	Extremely thin thickness, extremely high precision, often used in high-end packaging and special fields.

Aluminum foil alloy type

Aluminum foil is a lightweight and highly ductile material. It can be divided into multiple series according to different application requirements. Common series include 1000 Series, 3000 Series, 5000 Series, e 8000 Series. Each series has a large difference in alloy composition.

Aluminum foil alloy series

Série de liga	Características	Common types
1xxx series aluminum foil alloy	mainly composed of pure aluminum and a very small amount of other elements, with high aluminum purity, low strength, good plasticity, strong corrosion resistance, and widely used in aluminum foil production. 1 series aluminum alloy aluminum foil is very soft and easy to process and form, but its strength is low and its heat resistance is not very good.	1050 folha de alumínio 1060 folha de alumínio 1070 folha de alumínio 1100 folha de alumínio 1200 folha de alumínio 1235 folha de alumínio 1350 folha de alumínio
3xxx series aluminum foil alloy	3xxx series aluminum foil alloy: 3000 series aluminum foil is a general-purpose aluminum alloy. In addition to aluminum and a small amount of manganese, it also includes some other elements such as copper, magnésio, and tempering agents. 3 series aluminum alloy aluminum foil is stronger than 1 liga de alumínio em série, and adding copper to aluminum alloy can increase its hardness.	3003 folha de alumínio 3004 folha de alumínio 3005 folha de alumínio 3105 folha de alumínio
5xxx series aluminum foil alloy	5000 series aluminum foil uses magnesium (mg) as the main alloying element, and may add a small amount of manganese (Mn), chromium (Cr) and other elements to form a medium-strength aluminum-manganese-magnesium series alloy. It has high compressive strength and tensile strength, as well as good fatigue limit. The 5xxx series has high ductility and is easy to process in a variety of ways, such as cold working and hot working.	5005 folha de alumínio 5052 folha de alumínio
8xxx series aluminum alloy foil	8000 series aluminum foil is mainly composed of aluminum, tin and other elements such as copper and magnesium. 8 series aluminum alloy aluminum foil is stronger than 1 série e 3 ligas de alumínio em série, has better corrosion resistance and hardness, and also has good weldability and heat resistance, so it is widely used in high temperature environments. 8 series aluminum alloy has good softness and plasticity, and is often used to make dust-free trays, lamp holder materials, embalagem de alimentos, embalagens farmacêuticas, etc..	8011 folha de alumínio 8021 folha de alumínio 8079 folha de alumínio

What are the alloy tempers of aluminum foil?

Folha dura: Aluminum foil that has not been softened after rolling may have residue on the surface, so it needs to be degreased before printing, lamination and coating. If it is used for forming, pode ser usado diretamente.

Folha semidura: The hardness is between hard foil and soft foil, usually used for forming.

Folha macia: Aluminum foil that is completely annealed and softened after rolling, the material is soft and there is no residual oil on the surface. Soft foil is widely used in packaging, materiais compósitos, electrical materials and other fields.

Processing types of aluminum foil

Aluminum foil is soft and can be processed in various forms. The surface can be processed by coating, gravação em relevo, laminating, printing and other processing methods.

Color-coated aluminum foil

Color-coated aluminum foil is a kind of aluminum foil product with color coating, which is made of pure aluminum or aluminum alloy plate after a series of processing, including smelting, rolling, annealing and other steps, and then undergoes special surface treatment.
Color Coated Aluminum Foil is mainly composed of two parts: aluminum substrate and color coating. The aluminum substrate provides good mechanical properties and corrosion resistance, while the color coating gives the product rich colors and decorative effects. Color-coated aluminum foil is therefore widely used in construction, home appliances, embalagem, decoration and other fields.

Embossed aluminum foil

Embossed aluminum foil is a material that forms a concave and convex pattern on the surface of aluminum foil through a mechanical embossing process. Embossed aluminum foil is widely used in decoration, embalagem, construction and other fields due to its unique surface texture and excellent performance. The embossing process can enhance the reflectivity and heat insulation of aluminum foil, so that it can help reflect sunlight and reduce heat transfer in applications such as construction and automotive interiors.
