Details
An iron-aluminum nitride pot is not made from a single material; rather, it’s a composite cookware item created by treating an iron-based material through a nitriding process. The core technology behind this process is high-temperature nitriding: the raw iron pot blank is placed in a sealed container and exposed to nitrogen-containing gases such as ammonia. Under conditions of 550–600°C for more than two hours, nitrogen atoms bond with iron atoms to form a dense iron nitride layer (Fe₃N/Fe₄N). This process does not involve any chemical coatings; instead, it relies on atomic-level reactions to create a protective layer that integrates seamlessly with the pot body itself.
The nitrided layer endows cookware with three key characteristics: First, it significantly enhances rust resistance. The iron nitride layer isolates moisture and air from contacting the metal surface, reducing the release of iron ions—making it particularly suitable for cooking acidic ingredients. Second, the surface hardness reaches over HV800, providing wear resistance that is 3 to 5 times greater than that of conventional iron cookware, enabling it to withstand scratches from metal utensils. Third, the microstructure is dense and smooth; combined with the natural oil film formed after seasoning, this creates a physically non-stick effect without any risk of high-temperature decomposition.
Some products feature a composite substrate made of iron and aluminum. The aluminum alloy layer enhances thermal conductivity uniformity while preserving the heat-storage properties of the iron layer, striking a balance between high-heat stir-frying needs and energy efficiency. It’s important to note that nitrided cookware should be kept away from prolonged soaking or cleaning with strong alkaline detergents to prevent damage to the nitride coating. Compared to traditional iron pans, these cookware pieces are easier to maintain; and compared to chemically coated pans, they eliminate the risk of coating flaking, making them ideal for cooking scenarios that prioritize health and durability.
