Hello, I am sorry for any confusion. Nordic Ware has two major types of construction for Bundt Pans. Cast Aluminum and Formed Aluminum. Much of the decision, when choosing which construction you prefer, is based on personal choice. Both perform and release well. Many people will choose the formed pans for the lower price point, ease of lifting the pan, even when filled with Batter, and faster baking time. Others choose the Cast pans for the beauty and heirloom quality. Kind regards, Nordic Ware Customer Experience Team.
