ما هي لفائف الألمنيوم ورقائق الألومنيوم?

ورق ألومنيوم: Aluminum foil is a thin sheet of aluminum, typically less than 0.2 ملليمتر (مم) سميك. It is commonly used for wrapping food, التعبئة والتغليف, insulation and cooking.
Aluminum coils: Aluminum coils are continuous rolls of aluminum sheets commonly used in industrial applications such as roofing, بناء, automotive and manufacturing.

The difference between aluminum coil and aluminum foil thickness:

ورق ألومنيوم: Aluminum foil is very thin, عادة 0.006 مم ل 0.2 مم (6 microns to 200 ميكرون). It is available in various thicknesses depending on the specific application.

لفائف الألومنيوم: 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	ورق ألومنيوم	Aluminum Coils
سماكة	Very thin, عادة 0.006 مم ل 0.2 مم	Thicker, عادة 0.2 mm to several millimeters
المرونة	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
الانتهاء من السطح	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
المقاومة للتآكل	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:
  - تغليف الطعام (يلف, lining, and covering)
  - عازلة (thermal and sound)
  - Cooking and baking (as trays or covers)
  - Household and kitchen applications (covering dishes, lining grill pans)
  - Electrical applications (التدريع)
- Aluminum Coils Uses: Aluminum coils are commonly used for:
  - Roofing and cladding
  - Construction materials (siding, gutters, downspouts)
  - قطع غيار السيارات (body panels, trim)
  - Manufacturing processes (sheet metal fabrication, stamping)
  - Heat exchangers and HVAC systems

Manufacturing Process of aluminum foil coil

ورق ألومنيوم: 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.
