Aluminum foil can be classified into different thickness ranges, with each range corresponding to specific applications and uses. Here are some common classifications of aluminum foil based on thickness:
1. Heavy Duty: Heavy-duty aluminum foil is typically 0.024 to 0.038 mm (0.9 to 1.5 mils) thick. It is stronger and more durable than standard aluminum foil, making it ideal for grilling, baking, and other high-heat applications.
2. Standard: Standard aluminum foil is usually 0.016 to 0.024 mm (0.6 to 0.9 mils) thick. It's commonly used for wrapping food, storing leftovers, and other general kitchen applications.

3. Light Gauge: Light gauge aluminum foil is typically 0.008 to 0.015 mm (0.3 to 0.6 mils) thick. It's suitable for covering dishes, wrapping sandwiches, and other lightweight kitchen applications.
4. Extra Heavy Duty: Extra heavy-duty aluminum foil is usually 0.038 to 0.051 mm (1.5 to 2.0 mils) thick. It is used in industrial insulation, cooking, and other heavy-duty applications.
Note that the specific thickness ranges and classification names can vary between manufacturers and regions.
