What are the advantages and disadvantages of aluminum foil?

Aluminum foil has several advantages, including its affordability, ease of use, and excellent heat conductivity, making it ideal for cooking and food preservation. It's also lightweight, flexible, and resistant to corrosion. However, it has some disadvantages as well. Aluminum foil is not biodegradable and contributes to environmental waste, and its use can lead to the release of potentially harmful aluminum particles into food, especially when used at high temperatures. Additionally, it can be a fire hazard if used improperly, such as in cooking over an open flame.
