How Aluminium Makes Steel Cookware Better

Aluminium is added to steel pots and pans to combine the benefits of both materials. Aluminium is lightweight, conducts heat well, and is inexpensive, while steel is strong, durable, and made to last. By adding a layer of aluminium to steel, you get a pot or pan that is strong and durable but also lightweight and a good conductor of heat. This combination provides excellent performance, resulting in evenly cooked food. Additionally, aluminium-steel cookware is safe for dishwashers and resistant to rough handling.

Aluminium is lightweight, making it easy to handle

Aluminium is a lightweight metal with a density of 2.7 kg per dm3. It is about three times lighter than steel. This makes aluminium cookware extremely lightweight and easy to handle. For example, aluminium pots and pans are easy to manoeuvre around the stove and handle in and out of the oven. This is especially useful for people who do not want to use heavy pots and pans when cooking.

The lightweight property of aluminium is also advantageous in other applications where weight savings are critical, such as in the aerospace and automotive industries. For instance, the Wright Brothers used an aluminium and copper alloy to cast the engine block for their first airplane, as they knew it was imperative to have a lightweight engine.

Aluminium's lightweight characteristic is due to its low density. Despite being lightweight, aluminium is a strong, tough, and elastic material. This relative strength makes it well-suited for a wide range of applications in various sectors. Additionally, aluminium's low density makes it easy to form into any desired shape.

Aluminium is also an excellent conductor of heat. This property, combined with its lightweight nature, makes it a popular choice for cookware. Aluminium-made pots and pans heat up faster on the stove and cool down quickly, becoming safe to touch within a shorter time frame. However, aluminium cookware is not as good at retaining heat due to its lightweight nature.

It is a good conductor of heat, distributing it quickly and evenly

Aluminium is a good conductor of heat, distributing it quickly and evenly. This is due to its strong conductivity, which allows an aluminium-made pot to cook food evenly by distributing heat equally. Aluminium is simply one of the best heat conductors, allowing you to enjoy fast and even heat distribution across the cooking surface. This minimises the risk of hot spots for even cooking with precise temperature control, ultimately yielding fantastic cooking results. This is why aluminium is a top choice for cooking delicate foods like chicken, fish, and vegetables.

Aluminium is also lightweight, which means easy manoeuvrability around the stove and handling in and out of the oven. It is also inexpensive and easy to produce, coming in a range of shapes and sizes. However, aluminium is thin and can warp very easily, and is more prone to damage. It is also reactive, meaning it reacts with acidic ingredients like wine, citrus, and tomatoes, and imparts a metallic taste.

Therefore, for the best of both worlds, consider buying cookware containing both aluminium and stainless steel. By incorporating these two different metals, the result is a pot and pan that provides more than the sum of its parts. The aluminium and stainless steel cookware have a strong structure and are good at conducting heat. The stainless steel on both sides keeps the aluminium inert, preventing it from chemically reacting with food. Safe and durable, this type of cookware is dishwasher-friendly and provides excellent performance that results in evenly cooked food.

Aluminium is inexpensive compared to other materials

Aluminium is relatively inexpensive compared to other materials used in making pots and pans, such as stainless steel. The price difference is due to the absence of a cladded construction in aluminium, which is commonly found in stainless steel. This makes the production of aluminium less expensive, as less metal is required to manufacture cookware.

Aluminium is also cheaper than stainless steel when compared by volume. However, stainless steel is denser than aluminium, so for the same weight, aluminium can be more expensive. Nevertheless, the price of aluminium and steel fluctuates over time, depending on the distributor and the global supply and demand. For instance, the price of steel is influenced by the cost of iron and bauxite ore, while the price of stainless steel is affected by the fluctuating price of nickel, an alloying agent.

Aluminium is a desirable metal for cookware due to its lightweight and elastic properties. It is highly conductive, allowing for even heat distribution, which is ideal for cooking. Additionally, aluminium is corrosion-resistant and does not rust, making it a popular choice for kitchenware.

It is not induction compatible

Aluminium is added to steel pots and pans to create a product that benefits from the properties of both materials. Aluminium is lightweight, a good conductor of heat, inexpensive, and cools quickly. Steel, on the other hand, is strong, durable, scratch-resistant, corrosion-resistant, and non-reactive. However, one of the downsides of adding aluminium to steel pots and pans is that the resulting cookware is not induction compatible.

Induction cooktops work by creating a magnetic field between the pot and the magnetic coils beneath the cooking surface. The energy created in the electromagnetic field then heats the contents of the pot. For cookware to be compatible with induction cooktops, it must contain ferromagnetic materials, such as iron or steel.

Aluminium does not contain ferromagnetic materials and therefore does not generate heat when used on an induction cooktop. While some manufacturers have started adding a magnetic layer to the bottom of aluminium pans, older, non-magnetic pans will not work on induction stoves.

To test whether a pot or pan is compatible with an induction cooktop, you can simply hold a magnet to the bottom of the cookware. If the magnet sticks, the cookware will work on an induction cooktop. If there is no pull on the magnet, the cookware does not contain the right metals and will not generate heat.

Aluminium is a reactive material, and can react with acidic ingredients

Aluminium is a reactive metal that can react with acidic ingredients such as wine, citrus fruits, tomatoes, chilli, barbecue sauce, and chutney. When aluminium is used to cook acidic foods, it can result in bitter flavours and duller colours for the food, as well as possible damage and discolouration of the cookware. Leafy vegetables and acidic foods are also known to absorb the most aluminium.

Aluminium is added to steel pots and pans to improve their durability, conductibility, and reactivity abilities. However, when it comes to cooking with aluminium, it is important to be aware of its reactivity, especially with acidic ingredients.

The reactivity of aluminium with acidic ingredients can be explained by the fact that aluminium is a reactive metal. When it comes into contact with acids, such as those found in wine, citrus fruits, or tomatoes, it undergoes a chemical reaction. This reaction can affect both the taste and appearance of the food being cooked, as well as the condition of the cookware itself.

The presence of aluminium in steel pots and pans can offer improved heat conduction and weight reduction. However, when cooking with aluminium, it is recommended to avoid recipes that call for acidic and alkaline ingredients, as these can cause a reaction that imparts a metallic taste and discolouration to the food.

To prevent the negative effects of aluminium reactivity when cooking with acidic ingredients, it is recommended to use non-reactive cookware, such as stainless steel or hard-anodized aluminium. By choosing the appropriate cookware, you can ensure that your food maintains its intended taste, colour, and integrity, while also preserving the condition of your cookware.
