1. Ang kapal: Aluminum foil can be produced in a wide range of thicknesses, from ultra-thin (less than 0.001 pulgada) to heavy-duty (0.025 inch or more). Thinner foils are more flexible and easier to handle, while thicker foils offer greater strength and durability.
2. Lakas ng loob: Aluminum foil has excellent tensile strength, tear resistance, and puncture resistance. These properties make it ideal for use in packaging and other applications where the material needs to withstand stress and strain.
3. Barrier properties: Aluminum foil is an effective barrier against moisture, gases, light, and odors. It can help to preserve the freshness, flavor, and aroma of food and other products.
4. Heat resistance: Aluminum foil has excellent heat resistance and can withstand temperatures of up to 600°F (315°C) without melting or degrading. This property makes it suitable for use in cooking and baking applications.
5. Electrical conductivity: Aluminum foil has good electrical conductivity and can be used as a conductor in electrical applications.
6. Surface finish: The surface finish of aluminum foil can affect its performance characteristics, such as its barrier properties and printing capabilities. Foils can be produced with a range of finishes, from matte to high-gloss.
7. Alloy composition: The alloy composition of aluminum foil can affect its mechanical properties and corrosion resistance. Common alloys used for foil production include 1100, 1145, 1235, 8011, at 8079.

Overall, aluminum foil is a versatile material that offers a wide range of performance characteristics, making it suitable for a variety of applications, including packaging, cooking, and electrical engineering.
