Heavy-gauge hard anodized aluminum construction for durability. The dual-layer, metal-utensil safe nonstick interior makes the cooking experience even more enjoyable and the cleanup quick. The comfortable stainless steel handles are fully cast and riveted onto pans for strength and stability over a lifetime of use. The hammered stainless steel lids add another beautiful feature and provide a tight seal to lock in flavor while simmering. Dishwasher safe and oven safe to 500°f for more convenience
