If you are looking for the most durable pressure cooker, then a hard-anodized one would be the best choice for you. That’s because it is made with extra layers of anodized layers that make it more sturdy and durable. Not just that but they are also corrosion and rust-free.

Non-stick coating:

Any hard anodized pressure cooker comes with non-stick coating which is an added advantage. This prevents the food from sticking on the sidewalls of the cooker.

On the other hand, we have aluminum and stainless steel pressure cookers that don’t come with any non-stick coating. As a result, the food always sticks to the side walls. This makes it harder to clean them. If you are looking for a convenient option, then you should opt for a hard-anodized pressure cooker.

You can even use a scrub to clean them. There is no need for you to worry about your cooker getting damaged.

On the other hand, a hard-anodized cooker needs special care while cleaning. If the coating on top is not cleaned properly, it can get damaged. Also, you cannot wash them in a dishwasher or use a scrub.

Heat conductivity:

In terms of heat conductivity, aluminum happens to be the best choice. It not only distributes the heat properly but it also takes very little time to cook with an aluminum cooker.

Even hard-anodized cookers are known to distribute the heat evenly and thus, it promotes fast cookers. But stainless steel cookers are not good at distributing the heat evenly. This is where it loses to the other two types of cookers.


There are pressure cookers in each variant at different price brackets. However, the price often differs based on the nickel content in the cookware. For instance, the price will be more when you choose a high-quality cooker and vice versa. Some of the cookers can be expensive but in the end, it is worth every penny.

Stainless steel cookers are usually the ones that come with a higher price tag. Whereas the hard-anodized ones are available in a moderate range. But if you are looking for the most affordable option, then aluminum cookers are the best.
