Zwilling–the new owner of Demeyere–loves to rebrand its cookware, which is why we now have three nearly-identical variants of Demeyere Industry5.
As of July 2016, Demeyere also sells a Sur La Table exclusive called Demeyere Silver7 which is the same thing as Demeyere Atlantis and Proline, except with uglier lids and handles and double-walled (i.e., slightly better insulated) lids a la the Demeyere John Pawson line. The Demeyere Silver7 cladded (not disc-base) pans also have rims sealed with stainless steel. This means that there is no exposed aluminum layer at the rim of the pan. In theory this means you can use even the harshest dishwasher detergents with these pans and not have the aluminum layer eaten away by the detergent. But it’s not clear how big of a problem that really is, because many people have used cladded pans with exposed aluminum for years in dishwashers and been fine. (As of 2023, Demeyere makes Atlantis pieces the same way with protected rims just like Silver7, anyway.)
Also, Demeyere Aurora is NOT Industry5. Aurora has rivets and does not have Silvinox. Basically you’re just getting the thicker core (3mm total thickness compared to 2.6mm for All-Clad Stainless) and nothing else.
Demeyere also makes KitchenAid Professional 7-Ply Stainless Steel 10-Piece Cookware Set – Stainless Steel
which is made in Belgium and a clone of Demeyere Atlantis (reviewed here) except for a few differences: the handles and edges are slightly differently shaped, the capacities are slightly different (e.g., KitchenAid’s version is a 3.5 quart saute pan instead of 2.6 or 4.2 quarts), and the KitchenAid pieces have helper handles. Also, the skillets in the 7-ply KitchenAid line are 3mm thick and are thus effectively the same as Demeyere Industry5/Zwilling Sensation/Demeyere 5-Plus and NOT the 4.8mm of Demeyere Prolines (aka Atlantis Gold 5-star). Lastly, the KitchenAids are priced higher than Demeyere and available only as the aforementioned 10-piece set or as a 10 inch skillet
Other companies play a similar rebranding game. All-Clad TK (named after Chef Thomas Keller) is the same thing as All-Clad Copper Core and D5 except dressed differently: the handles curve more gently, the Copper Core pieces are not gouged out to expose the copper near the base of the cookware, and the lids are lollipop-style (discs with flat handles) which is more traditional and allows the use of the same lid on multiple cookware pieces of similar-but-different diameter–but which many people hate because condensation drips down from the overhand of the lid.
, though it’s applicable to the rest of the product line as well.
– Copper Core is made in the USA out of a five-layer sandwich: stainless, aluminum, copper, aluminum, and stainless (in order, from inside to out). For decorative reasons, All-Clad shaves off some exterior steel in order to expose the copper in a thin band around the perimeter of the pot or pan. Thus the decorative band is thinner (stainless-aluminum-copper) and is missing the exterior aluminum and stainless layers. Copper Core has about the equivalent of 0.91 mm copper, making it slightly more heat conductive than All-Clad Stainless (1 mm of copper is worth about 2 to 2.4 mm of aluminum in terms of heat-spreading power, depending on the exact alloy grades in question). Copper Core is a slightly better performer than All-Clad Stainless. It also heats up and cools down faster than All-Clad Stainless and spreads heat more evenly.
, though the 
is shaped and sized the same way. This review is applicable to the other pieces in the product line as well.
, though this review is applicable to other pieces in the product line. Cooks Standard Multi-Ply is an All-Clad Stainless knockoff made in China. It’s not as thick as the real thing, and it spreads heat worse as a result. It might also be somewhat more prone to warping over time due to the thinner metal. The Cooks Standard logo is apparently laser-etched onto the lid and bottom of every pot and pan in the lineup, which looks tacky to many people and makes it awkward to give as a gift. It can’t be scrubbed off, though you could probably sandpaper it off with some effort (and make the pan look even worse as a result).
