Zinc-aluminum-magnesium ingots can be used for coating steel materials to enhance their corrosion resistance and anti-corrosion properties. The dataset includes main raw and auxiliary materials, energy inputs, atmospheric emissions, and waste generated during the production process. By-products of this process include zinc oxide powder, sulfuric acid, steam, and electricity. Infrastructure such as equipment manufacturing and plant construction for production are not included within the system boundaries of the dataset. The life cycle inventory is compiled from data sourced from multiple references. The production process of zinc-aluminum alloy involves raw material preparation, batching, melting, casting, rolling, and heat treatment.
