Five-ply stainless clad cookware
Quick answer
Five-ply stainless clad's aluminium layers conducts heat at about 237 W/m-K, while the stainless cooking surface itself is only about 16. It works on induction and is oven safe to about 600F. It is best for long cooking where steady, even heat matters more than fast response.
Conductivity and density are published material properties. Oven ceilings are what manufacturers publish for this class of cookware and vary by brand.

| Five-ply stainless clad | 237 W/m-K aluminium layers, 16 at the surface | Yes | 600F | No |
| Disc-base stainless | 237 W/m-K aluminium disc in the base, 16 at the surface | Yes | 500F | No |

12 piecesWhat is five-ply stainless clad?
Five bonded layers, alternating stainless and aluminium, with a magnetic stainless exterior.
Five-ply buys evenness and stability, and pays for it in weight and slower response. It is not simply a better three-ply.
How it behaves on the heat
Its aluminium layers conducts heat at about 237 W/m-K, while the stainless cooking surface itself is only about 16. That figure sits near the top of the range, second only to copper. Heat retention is medium to high, responsiveness is medium, because the extra mass takes longer to change temperature, and evenness is very high, and the extra stainless layer damps hot spots further.
Conductivity and heat capacity are different things and it is worth keeping them apart. Conductivity is how fast heat moves through the material. Heat capacity is how much energy the material holds once hot. Cast iron conducts poorly and holds a great deal, which is exactly why it sears well: the pan barely cools when cold food lands on it.
Induction, oven and care
It works on induction. The exterior layer is magnetic stainless, so a magnet sticks and an induction hob couples to it. The settling test is a fridge magnet on the base: a firm grip means it works.
The oven ceiling is about 600F. All-Clad publishes 600F oven and broiler safe for D5. Dishwasher guidance: Usually permitted, hand washing preferred. It is not reactive, so acidic food presents no problem.
What it is genuinely best at
Long cooking where steady, even heat matters more than fast response.
On sticking: Yes, same as any bare stainless surface.

Common questions
Does five-ply stainless clad work on induction?
Yes. The exterior layer is magnetic stainless, so a magnet sticks and an induction hob couples to it. The reliable test is a fridge magnet against the base: a firm grip across the whole base means the pan will work, a grip only in the centre means uneven heating, and no grip means it will not work at all.
How hot can five-ply stainless clad go in the oven?
About 600F. All-Clad publishes 600F oven and broiler safe for D5. Remember that the ceiling for any assembled pan is the lowest of its cooking surface, its handle and, if it goes in covered, its lid, and the handle is very often the lowest of the three.
Is five-ply stainless clad dishwasher safe?
Usually permitted, hand washing preferred. Even where a dishwasher is technically permitted, hand washing extends the life of almost every kind of cookware, because detergents are aggressive and the heat cycle is harder on coatings and finishes than anything that happens during cooking.
Can I cook acidic food in five-ply stainless clad?
Yes. This material is inert, so tomatoes, wine, vinegar and citrus present no problem however long they cook. That is one of the main practical reasons to own it.
What is five-ply stainless clad best at?
Long cooking where steady, even heat matters more than fast response. No single cookware material is good at every job, which is why a mixed kitchen outperforms a matched set at every budget. Choose each vessel for what it will actually be used for rather than buying everything in one construction.
