The aluminum sheet circle is a lightweight metal with excellent thermal conductivity, but the aluminum is a soft metal, so the cookware made entirely of aluminum sheet circles is liable to leave scratches or sheet circleoloration. A non-stick coating can be applied to the outer layer of the aluminum cookware. Teflon coatings are the most common cookware.
