Copper, lined cookware
Quick answer
Copper, lined conducts heat at about 401 W/m-K, does not work on induction, and is oven safe to about 450F. Sugar work, delicate sauces and anything where the pan must respond the instant the heat changes.
Conductivity and density are published material properties. Oven ceilings are what manufacturers publish for this class of cookware and vary by brand.
| Material | Conductivity | Induction | Oven ceiling | Reactive |
|---|---|---|---|---|
| Tri-ply stainless clad | 237 W/m-K | Yes | 600F | No |
| Five-ply stainless clad | 237 W/m-K | Yes | 600F | No |
| Disc-base stainless | 237 W/m-K | Yes | 500F | No |
| Bare cast iron | 52 W/m-K | Yes | 700F | Yes |
| Carbon steel | 50 W/m-K | Yes | 600F | Yes |
| Enamelled cast iron | 52 W/m-K | Yes | 500F | No |
| PTFE nonstick | 237 W/m-K | Depends | 400F | No |
| Ceramic nonstick | 237 W/m-K | Depends | 350F | No |
| Bare or anodised aluminium | 237 W/m-K | No | 500F | Yes |

What is copper, lined?
A thick copper body lined with stainless or tin, since bare copper reacts with food.
Copper conducts about twenty five times better than stainless and roughly eight times better than cast iron. You are buying control, and paying for it in price, weight and upkeep.
How it behaves on the heat
Its conductivity of about 401 W/m-K sits at the top of the range, alongside aluminium and copper. Heat retention is medium, and responsiveness is the highest of any cookware material. Evenness is the highest of any cookware material.
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 does not work on induction. Copper is not ferromagnetic. A copper pan works on induction only if a steel disc is bonded to its base, which most traditional copper is not. The settling test is a fridge magnet on the base: a firm grip means it works.
The oven ceiling is about 450F. Tin-lined copper must stay well below the melting point of tin, which is about 450F. Stainless-lined copper has no such limit. Dishwasher guidance: No.. It is not reactive, so acidic food presents no problem.
What it is genuinely best at
Sugar work, delicate sauces and anything where the pan must respond the instant the heat changes.
On sticking: Yes, as the lining is stainless or tin.

Common questions
Does copper, lined work on induction?
No. Copper is not ferromagnetic. A copper pan works on induction only if a steel disc is bonded to its base, which most traditional copper is not. 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 copper, lined go in the oven?
About 450F. Tin-lined copper must stay well below the melting point of tin, which is about 450F. Stainless-lined copper has no such limit. 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 copper, lined dishwasher safe?
No. 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 copper, lined?
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 copper, lined best at?
Sugar work, delicate sauces and anything where the pan must respond the instant the heat changes. 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.
