Quaternary alloy can be used for rust prevention and atmospheric corrosion resistance; this dataset includes major raw and auxiliary materials, energy, atmospheric emissions, and waste from the production process, while infrastructure such as manufacturing of production equipment and construction of facilities are excluded from the system boundary; the life cycle inventory is compiled from data sourced from multiple references; quaternary alloy production includes processes such as raw material preparation, alloy formulation, heating and melting, cleaning and rust removal, surface treatment, electroplating, and finished product inspection.
