Galvanized aluminum-magnesium ingots can be used for coatings to improve surface corrosion resistance; the dataset includes major raw and auxiliary materials, energy, and waste from the production process, while infrastructure such as production equipment manufacturing and factory construction is not included within the system boundary; the life cycle inventory is compiled from data sourced from multiple references; the production process of galvanized aluminum-magnesium ingots includes pretreatment (cleaning, degreasing, and pickling), electroplating, and post-treatment (e.g., passivation, sealing).
