Naučite li razliku između aluminijske folije i aluminijskih kolutova?

Aluminijska folija i aluminijska zavojnica svestrani su materijali od aluminijskih legura koji se koriste u različitim primjenama u raznim industrijama. Legura aluminijske zavojnice i legura aluminijske folije imaju slična svojstva u mnogim aspektima, ali također imaju mnogo različitih karakteristika. Huawei će napraviti detaljnu usporedbu između njih dvoje u smislu svojstava, koristi, itd.:

Što su aluminijske zavojnice i aluminijska folija?

Aluminijska folija: Aluminum foil is a thin sheet of aluminum, typically less than 0.2 milimetara (mm) gusta. It is commonly used for wrapping food, pakiranje, insulation and cooking.
Aluminum coils: Aluminum coils are continuous rolls of aluminum sheets commonly used in industrial applications such as roofing, konstrukcija, automotive and manufacturing.

The difference between aluminum coil and aluminum foil thickness:

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

Aluminum coil: 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	Aluminijska folija	Aluminum Coils
Debljina	Very thin, typically 0.006 mm to 0.2 mm	Thicker, typically 0.2 mm to several millimeters
Fleksibilnost	Highly flexible and easily bendable	Less flexible compared to foil, but still somewhat bendable
Strength	Relatively low tensile strength	Higher tensile strength, suitable for structural applications
Površinska obrada	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
Otpornost na koroziju	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:
  - Ambalaža za hranu (omatanje, lining, and covering)
  - Izolacija (thermal and sound)
  - Cooking and baking (as trays or covers)
  - Household and kitchen applications (covering dishes, lining grill pans)
  - Electrical applications (shielding)
- Aluminum Coils Uses: Aluminum coils are commonly used for:
  - Roofing and cladding
  - Construction materials (siding, gutters, downspouts)
  - Automotive parts (body panels, trim)
  - Manufacturing processes (sheet metal fabrication, stamping)
  - Heat exchangers and HVAC systems

Manufacturing Process of aluminum foil coil

Aluminijska folija: 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.
