You cannot use metal utensils on aluminum pans. Since aluminum is a soft metal, using metal utensils on an uncoated aluminum surface can damage its surface. You can use metal utensils, except for sharp kitchen knives, on hard-anodized aluminum pans. The anodization process adds a thick layer to the aluminum, which increases its durability and scratch resistance.

Stainless steel is a highly durable material and doesn’t chip, peel or scratch easily like soft metals such as aluminium. As chefs have to handle vigorous, pan-clanging cooking day in and day out, they tend to lean toward stainless steel cookware instead of aluminium cookware.

Another massive reason why stainless steel cookware has always been the chef’s favourite is the fact that it doesn’t react with acidic foods. This means, unlike aluminium cookware, stainless steel keeps metals from leaching into your meals, resulting in healthier and tastier servings.

However, aluminium cookware has its own set of advantages too. For example, aluminium is a faster and more responsive conductor of heat, making it a great choice for fry pans.

They're obviously more expensive than other non-stick pans, but they last longer. So if you're looking for a frying pan that will last you a long time, get a hard-anodized one.
