Quick answer: Aluminum heats fastest and is lightest, but plain aluminum doesn't work on induction. Stainless steel with an aluminum core (3-ply) gives you aluminum's heat with a durable, non-reactive stainless surface and works on induction. Nonstick is easiest for eggs and fish but needs gentle heat and utensils. Most well-equipped kitchens use a mix of all three.
Choosing cookware usually comes down to three materials: aluminum, stainless steel and nonstick. Each cooks differently, needs different care and suits different stoves. This guide compares them side by side, so you can pick the right pan for the way you cook.
| Aluminum | 3-Ply stainless steel (aluminum core) | Nonstick (coated aluminum) | |
|---|---|---|---|
| Heat speed | Very fast | Fast (aluminum core) | Very fast |
| Heat response | Reacts immediately to flame changes | Good | Reacts quickly |
| Weight | Light | Heavier | Light |
| Cooking surface | Bare aluminum | 18/10 stainless steel | Nonstick coating |
| Best for | Sautéing, sauces, pasta, high-volume cooking | Searing, browning, deglazing, acidic dishes | Eggs, fish, crepes, delicate foods |
| Induction | No, unless built with an induction base | Yes | Only with an induction base |
| Heat level | Low to high | Low to high | Low to medium |
| Utensils | Avoid sharp metal | Most utensils | Wood or silicone only |
Aluminum conducts heat much better than regular stainless steel and is relatively light, so a pan heats quickly, spreads heat across the base and reacts the moment you change the flame. In a busy kitchen, that speed and control matter, and a lighter pan is easier to lift and toss all day. That is why thick aluminum has been the backbone of professional Italian kitchens for generations, and the material Agnelli has worked with since 1907.
Thickness matters. A thin aluminum pan can warp and develop hot spots, while thick professional aluminum spreads heat evenly. Agnelli's aluminum cookware comes in 3mm and heavy-duty 5mm versions, both made from 100% recycled aluminum.
3-ply (tri-ply) cookware bonds three layers together: stainless steel outside, an aluminum core in the middle, and stainless steel inside. Stainless steel on its own does not conduct heat very well, so the aluminum core does the heating while the stainless steel gives you a durable, easy-to-clean cooking surface.
Agnelli's Alu-Inox 3-Ply line is built from 10% stainless steel on the outside (which makes it induction-ready), 80% aluminum for heat conduction and 10% 18/10 stainless steel on the inside, with a 3mm total thickness and a mirror-polished finish. It works on induction, electric, radiant and gas cooktops.
Choose nonstick when food release matters more than a hard sear: eggs, omelettes, crepes, fish fillets and vegetables. Nonstick also makes cleanup quick. In exchange, it needs gentler treatment: cook on low to medium heat, don't heat it empty, use wood or silicone utensils, and wash by hand.
Agnelli offers classic nonstick (3mm aluminum with Teflon® Platinum Plus), Shark Skin (Powered Greblon Technology, PFOA-free and induction-compatible) and All-Black 3mm.
For induction, choose 3-ply stainless steel or a pan with a dedicated induction base. With Agnelli, that means Alu-Inox 3-Ply, Shark Skin, or pieces from the Induction Cookware collection. Every product page states which cooktops the pan works on.

Neither is better for everything. Aluminum heats faster and is lighter; stainless steel is more durable and non-reactive. 3-ply cookware combines both: an aluminum core for heat with a stainless steel surface.
Not on its own, because aluminum isn't magnetic. It works on induction only when the pan has a magnetic stainless steel layer or an induction base, as in Agnelli's Alu-Inox 3-Ply and Shark Skin lines.
Wash by hand with warm water, mild dish soap and a non-abrasive sponge, then dry completely before storing. Avoid steel wool and harsh abrasive cleaners.
It depends on how it's used. Low to medium heat, non-metal utensils and hand washing help any nonstick coating last much longer.
Professional aluminum pans are thick enough to resist warping and spread heat evenly. Agnelli's professional lines are 3mm and 5mm.
