Apprenez-vous la différence entre le papier d'aluminium et les bobines d'aluminium?

Le papier d'aluminium et la bobine d'aluminium sont tous deux des matériaux en alliage d'aluminium polyvalents utilisés dans différentes applications dans diverses industries.. L'alliage de bobine d'aluminium et l'alliage de feuille d'aluminium ont des propriétés similaires à bien des égards., mais ont aussi de nombreuses caractéristiques différentes. Huawei fera une comparaison détaillée entre les deux en termes de propriétés, les usages, etc.:

Que sont les bobines d'aluminium et le papier d'aluminium?

Feuille d'aluminium: Aluminum foil is a thin sheet of aluminum, typically less than 0.2 millimètres (millimètre) épais. It is commonly used for wrapping food, emballage, insulation and cooking.
Aluminum coils: Aluminum coils are continuous rolls of aluminum sheets commonly used in industrial applications such as roofing, construction, automotive and manufacturing.

The difference between aluminum coil and aluminum foil thickness:

Feuille d'aluminium: Le papier d'aluminium est très fin, typically 0.006 mm à 0.2 millimètre (6 microns to 200 microns). It is available in various thicknesses depending on the specific application.

Bobine d'aluminium: Aluminum coil is thicker than aluminum foil. Their thickness ranges from approximately 0.2 mm to several millimeters, depending on the intended use.

Aluminum foil vs aluminum coil properties:

Property	Feuille d'aluminium	Aluminum Coils
Épaisseur	Very thin, typically 0.006 mm à 0.2 millimètre	Plus épais, typically 0.2 mm to several millimeters
La flexibilité	Highly flexible and easily bendable	Less flexible compared to foil, but still somewhat bendable
Force	Relatively low tensile strength	Higher tensile strength, suitable for structural applications
Finition de surface	Often shiny on one side (reflective), matte on the other	Can have various surface finishes depending on the application
Conductivité thermique	Good heat conductivity	Good heat conductivity, suitable for heat transfer applications
Résistance à la corrosion	Corrosion-resistant	Corrosion-resistant, especially when coated or treated for protection

The difference between aluminum coil and aluminum foil uses

- Aluminum Foil Uses: Aluminum foil is commonly used for:
  - Emballages alimentaires (emballage, lining, and covering)
  - Isolation (thermal and sound)
  - Cooking and baking (as trays or covers)
  - Household and kitchen applications (covering dishes, lining grill pans)
  - Applications électriques (blindage)
- Aluminum Coils Uses: Aluminum coils are commonly used for:
  - Roofing and cladding
  - Construction materials (siding, gutters, downspouts)
  - Pièces automobiles (body panels, trim)
  - Manufacturing processes (sheet metal fabrication, stamping)
  - Heat exchangers and HVAC systems

Manufacturing Process of aluminum foil coil

Feuille d'aluminium: Aluminum foil is typically produced by rolling aluminum ingots through rolling mills to achieve the desired thickness. The foil is then annealed and may undergo additional treatments for specific properties.

Aluminum Coils: Aluminum coils are produced in a similar manner to aluminum foil but are typically thicker and wider. The process involves hot or cold rolling of aluminum ingots or billets through rolling mills to produce continuous coils of various thicknesses and widths.
