Stainless Steel Pressure Cookers vs. Aluminum Pressure Cookers

The two most prominent types of pressure cookers are stainless steel and aluminum. Since they are both so different, it can be hard to decide which one you should invest in for your cooking.

While aluminum pressure cookers cost less, does that automatically mean they aren’t as good? Not necessarily. On the other hand, does that mean that the stainless-steel pressure cookers are better? That may not be true either.

In fact, both aluminum and stainless steel pressure cookers have their pros and cons, so it is up to you to decide which one is better for you. Shopping for a pressure cooker can get quite overwhelming due to the large volume of makes, models, and types, so this article is meant to give you more clarity on which pressure cooker you want.

Aluminum Pressure Cookers

Aluminum pressure cookers are much more affordable than their competitors because aluminum is a cheaper metal to buy. It is a great conductor of heat and is also a very lightweight material. Below are the pros and cons of aluminum pressure cookers:


  • They are less expensive than stainless steel pressure cookers.
  • They are lightweight and easy to transport.
  • They are a great conductor of heat and allow the heat to distribute equally to the food.
  • They are cost-effective because they are less expensive and work just as well as their competitors.


  • Because aluminum is a lightweight metal, it can eventually warp or become distorted. If it is bumped, it is more fragile than stainless steel.
  • They are less durable than their competitors and will not last as long.
  • Aluminum can get stained with time and use.

Stainless Steel Pressure Cookers

Stainless steel pressure cookers are a larger investment than aluminum pressure cookers, but the metal is much more durable and long-lasting. Stainless steel is a very strong metal, though it does not conduct heat to the level that aluminum does. Below are the pros and cons of stainless-steel pressure cookers:


  • Stainless steel is a very durable metal and will last a long time with no distortion.
  • As per the name, stainless steel is stainless. It will stay shiny and clean for years to come with no stains.
  • Because stainless steel is much heavier than aluminum, it is much more heavy-duty and durable meaning that it will likely last much longer than those made of aluminum.


  • Because of their weight and build, stainless steel pressure cookers can be quite impractical to move and transport.
  • Stainless steel does not conduct heat as well as aluminum so it will take much longer to heat up to cooking temperature.
  • These pressure cookers are much more expensive than aluminum ones.


Overall, there are pros and cons for both aluminum and stainless steel pressure cookers. While one is more expensive, the other is less durable. Because of this, it is important for you to weigh the pros and cons of both to decide which pressure cooker is the best fit for you.
