This is not an aluminum product. Even on Amazon, SUS430 is mostly used. This is a gold-plated product made of the highest grade stainless steel SUS304, which is resistant to rust, discoloration, and has a focus on smell and texture. For more details, here's the difference between SUS304 and SUS430. SUS304, a representative of austenitic stainless steel, and SUS430, a representative of ferritic stainless steel, are both commonly used materials. This article explains the differences between SUS304 and SUS430. Features of SUS304: SUS304, which contains 18% chromium and 8% nickel, is a representative material of austenitic stainless steel and has many excellent properties such as good corrosion resistance, workability, and weldability. It is also resistant to high-temperature oxidation and has high heat resistance in high-temperature environments (up to about 900°C), so it is also used as heat-resistant steel. It has sufficient hardness for general use, but it cannot be further hardened by quenching. SUS430: Although the appearance is almost the same except for the degree of gloss, unlike SUS430, which has strong magnetism, SUS304 does not have magnetism, so you can distinguish them by whether they are attracted to a magnet. However, when cold working such as bending or drawing is performed, work hardening occurs, increasing the hardness and also generating magnetism.
