Cuộn nhôm và lá nhôm là gì?

Giấy nhôm: Aluminum foil is a thin sheet of aluminum, typically less than 0.2 milimét (mm) dày. It is commonly used for wrapping food, bao bì, insulation and cooking.
Aluminum coils: Aluminum coils are continuous rolls of aluminum sheets commonly used in industrial applications such as roofing, sự thi công, automotive and manufacturing.

The difference between aluminum coil and aluminum foil thickness:

Giấy nhôm: Aluminum foil is very thin, tiêu biểu 0.006 mm đến 0.2 mm (6 microns to 200 micron). 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	Giấy nhôm	Aluminum Coils
độ dày	Very thin, tiêu biểu 0.006 mm đến 0.2 mm	Thicker, tiêu biểu 0.2 mm to several millimeters
Uyển chuyển	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
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
Chống ăn mòn	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:
  - Bao bì thực phẩm (gói, lining, and covering)
  - Vật liệu cách nhiệt (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

Giấy nhôm: 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.
