The All-Clad Copper Core Collection

features patented five-ply bonded construction with stainless-steel, aluminum and a copper center core to heat quickly and evenly with consistent performance. Copper-Core heats faster than other All-Clad styles due to the high heat conductivity of the inner copper layer exposed as a striking line of copper on the outside of the pan. Rolled edges on pots and pans help prevent drips when pouring and allow lids to fit tightly.
