Clad cookware is a sandwich of metals and it’s usually the inner core that conducts the heat evenly throughout the pan. What matters most are the quality of these materials versus the number of layers. Hestan NanoBond and ProBond are tri-ply construction with a highly efficient aluminum core called ProCore that delivers 35% greater heat conductivity than other aluminum-clad cookware for fast and even heating. Next to copper, it’s one of the most conductive metals for cookware. No need for extra layers that add unnecessary weight to the pan and in some cases even impedes the heat. Hestan cookware is designed to be high performance but lightweight and efficient.
