Učíte se rozdíl mezi hliníkovou fólií a hliníkovými cívkami??

Hliníková fólie a hliníková cívka jsou univerzální materiály z hliníkové slitiny používané v různých aplikacích v různých průmyslových odvětvích. Slitina hliníkové cívky a slitina hliníkové fólie mají v mnoha ohledech podobné vlastnosti, ale mají také mnoho různých vlastností. Huawei provede podrobné srovnání obou z hlediska vlastností, používá, atd.:

Co jsou hliníkové cívky a hliníková fólie?

Hliníková fólie: Aluminum foil is a thin sheet of aluminum, typically less than 0.2 milimetry (mm) tlustý. It is commonly used for wrapping food, obal, insulation and cooking.
Aluminum coils: Aluminum coils are continuous rolls of aluminum sheets commonly used in industrial applications such as roofing, konstrukce, automotive and manufacturing.

The difference between aluminum coil and aluminum foil thickness:

Hliníková fólie: Aluminum foil is very thin, typically 0.006 mm až 0.2 mm (6 microns to 200 mikronů). It is available in various thicknesses depending on the specific application.

Hliníková cívka: 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	Hliníková fólie	Aluminum Coils
Tloušťka	Very thin, typically 0.006 mm až 0.2 mm	Thicker, typically 0.2 mm to several millimeters
Flexibilita	Highly flexible and easily bendable	Less flexible compared to foil, but still somewhat bendable
Pevnost	Relatively low tensile strength	Higher tensile strength, suitable for structural applications
Surface Finish	Often shiny on one side (reflective), matte on the other	Can have various surface finishes depending on the application
Heat Conductivity	Good heat conductivity	Good heat conductivity, suitable for heat transfer applications
Odolnost proti korozi	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:
  - Balení potravin (obal, lining, and covering)
  - Izolace (thermal and sound)
  - Cooking and baking (as trays or covers)
  - Household and kitchen applications (covering dishes, lining grill pans)
  - Electrical applications (stínění)
- Aluminum Coils Uses: Aluminum coils are commonly used for:
  - Roofing and cladding
  - Construction materials (siding, gutters, downspouts)
  - Automobilové díly (body panels, trim)
  - Manufacturing processes (sheet metal fabrication, stamping)
  - Heat exchangers and HVAC systems

Manufacturing Process of aluminum foil coil

Hliníková fólie: 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.
