Which Pressure Cooker is Best for Health Steel or Aluminium


Which Pressure Cooker is Best for Health Steel or Aluminium

While getting a pressure cooker will help save time in the kitchen, choosing the right one can be difficult and time-consuming.

The two most prevalent pressure cooker materials that are easily accessible are steel and aluminum. You must weigh the benefits and drawbacks of each variety when selecting, as they each have different characteristics.

Is a pressure cooker made of aluminum better than one made of stainless steel?

Because they are lightweight, aluminum pressure cookers are a great option for cooking in large quantities. Compared to the other pressure cookers, they also cook much faster.

Using containers within the pressure cooker will prevent aluminum from coming into direct contact with the product immediately and eliminate any health risks from aluminum leaking into the food.

Although stainless steel pressure cookers are superior in terms of health benefits and ease of maintenance, aluminum pressure cookers still win the price and weight wars.


Because aluminum is much more lightweight than steel, a cooker made of aluminum will weigh less than a steel cooker of equal capacity.

It makes the cooker lightweight, making it simple to handle and operate.

Cooking Time

Due to its superior thermal conductivity, aluminum heats up significantly more quickly than steel in a pressure cooker.

An aluminum pressure cooker cooks much faster than a steel pressure cooker.

Quick to Clean

The metal pressure cooker tends to develop a parallel over time from use, making it appear dated and battered. It is easy to get rid of this, but cleaning up will take a lot of time and effort. On the other hand, the steel pressure cooker appears precisely the same. Over it, no such layers develop.


Because aluminum is significantly thinner and lacks the strength to maintain its shape over time, it is more susceptible to warping than other materials.

As you can see, and both pressure cookers have been used for the same amount of time, the steel one still looks far more admirable than the aluminum one.


Because it retains its luster and sheen over time, stainless steel earns its name. The stainless steel pressure cooker does not oxidize; in contrast, the aluminum first seems glossy until the initial shine is washed away and the metal begins to rust.

The pressure cooker changes color due to oxidation, trying to appear older and more used than it is.
These aluminum oxidation spots are exceedingly unsightly and difficult to remove. I’ve tried it several times, and every time I clean the cooker, the oxidized areas develop after the first few usages.

Beneficial to use

Stainless steel pressure cookers are healthier to use than aluminum ones. Utilizing an inner vessel instead of cooking directly in an aluminum pressure cooker is always recommended.

It is not advised to cook directly in an aluminum pressure cooker since, with time, the metal tends to become toxic.


Pressure cookers made of stainless steel are approximately twice as expensive as those made of aluminum. It is because aluminum pressure cookers are manufactured at a far lower cost than stainless steel pressure cookers, as aluminum metal is a much less costly raw material.


The stainless steel pressure cooker is resistant to leaching, whereas aluminum pressure cookers are susceptible, particularly when acidic foods are cooked in them.

Therefore, you should not cook acidic foods in your aluminum pressure cooker.

As you can see, we only have one aluminum pressure cooker, as I noticed over time that purchasing more was not worthwhile. All subsequent purchases were made of stainless steel and were well worth the cost.


Pros of Steel Pressure Cooker

  • Since stainless steel does not rust or change color over time, steel pressure cookers are simple to maintain. Cleaning and maintaining it over time won’t take much effort.
  • Cookers made of stainless steel are less prone to wrapping since steel is a heavier metal that keeps its shape even when exposed to heat.
  • Food cooked in steel is healthier because it does not leach into the food.
  • All food categories, especially citrus items, can be cooked in stainless steel.

Cons of Steel Pressure Cooker

  • Steel weighs more than other metals like aluminum, making it work harder.
  • Additionally, steel requires longer to heat up, cook, and attain pressure.
  • Additionally more expensive than other pressure cookers on the market are steel pressure cookers.

Pros of Aluminum Pressure Cooker

  • Aluminum pressure cookers are more accessible to manipulate than pressure cookers made from other metals, such as stainless steel.
  • Aluminum warms rapidly, making it faster to reach pressure and cook food.
  • Aluminum is a less expensive metal. Hence, aluminum pressure cookers are less costly than those made from other metals.

Cons of Aluminum Pressure Cooker

  • Aluminum’s low density makes it more susceptible to thermal deformation than other metals.
  • Aluminum rapidly loses its luster and develops a darker oxidized layer around it. This layer requires a lot of time and effort to clean. Maintaining aluminum pressure cookers can be difficult.
  • Aluminum can seep into food over time and contaminate it, making it unhealthy for human consumption. Aluminum combines with acidic foods to generate chemicals that enter food and, by extension, our bodies, causing various adverse effects.

Is Using an Aluminum Pressure Cooker Safe?

When cooking with acidic foods, avoiding a pressure cooker made of aluminum is best because the metal can leach into your food. However, cooking with nesting utensils inside the range might make the operation safer. Doing this will cook the food without coming into contact with the aluminum.


Aluminum pressure cookers are easier to use and cook food more quickly, but stainless steel pressure cookers are the apparent victor for their ease of upkeep and health advantages.

It is the reason I chose a stainless pressure cooker when I wanted a smaller pressure cooker to cook sides. For our family’s use, its health benefits and ease of maintenance outweigh those of the aluminum pressure cooker.
