Why We Make Multi-ply Cookware

Multi ply cookware is made of multiple layers of bonded material. Typically, the top and bottom layers of stainless steel are bonded around an aluminum or copper core.

Stainless steel is durable, but it is a poor conductor of heat. On the other hand, aluminum and copper have high thermal conductivity and are excellent at transferring and dissipating heat, but they are not as durable as steel. Therefore, multi-layer materials combines thermal conductivity and durability very well.

Generally speaking, multi-layer materials are aimed at the high-end market and the price will also be much more expensive than that of single-layer stainless steel.

Generally speaking, the thicker the cookware, the more durable it will be. Thick cookware heats more slowly but evenly than thin cookware, and stays warm longer. Generally speaking: Our three-layer material thickness is: 2.0mm 2.5 mm and 3mm Our five-layer material material thickness is 2.5mm 3.0mm

Use copper as the core layer because it is a better conductor of heat than aluminum. Copper is more expensive and adds to the cost of cookware.

We also produce copper Core cookware. The common thicknesses of five-layer copper or three-layer copper are 2.5mm and 3mm

At the same time, we also have some multi-layer copper products, and the copper is outermost. Its general composition is stainless steel + aluminum + copper. Such a multi-layer material  is not for induction. To solve this problems, our designer added a 430 induction plate after studying the aluminum pot.
