Why are iron and aluminum used for making cooking utensils?

Iron and aluminum are popular materials for cooking utensils due to their Excellent heat conductivity, which allows for even cooking and efficient heat distribution. Aluminum is lightweight and resistant to corrosion, making it easy to handle and durable. Iron, particularly when cast or treated, is robust and can retain heat well, making it ideal for frying and searing. Additionally, both metals can be easily shaped and molded into various utensil designs.
