Are old pots and pans made of aluminum?

Yes, old pots and pans are made of aluminum. Prior to the 1950s, most pots and pans were made of cast iron, but aluminum became increasingly popular as a cookware material in the mid-20th century. Aluminum is lightweight and conducts heat evenly, making it an ideal material for cooking. It was particularly favored for its low cost and durability. Cast iron remains popular for certain applications such as frying and grilling due to its ability to retain high temperatures and create the ideal searing surface.
