This dataset describes the process of casting primary aluminum ingots from liquid primary aluminum, specific to the operations used in 2011. The primary aluminum ingots are typically used as a raw material in various industries, including automotive, construction, and packaging, where the properties of aluminum such as lightweight, strength, and corrosion resistance are required. When using this dataset for Life Cycle Assessment (LCA), users should note that process-specific data pertains to the year 2011 and may not accurately represent current practices. Data users should ensure the PA (primary aluminum) and SA (secondary aluminum) data are appropriate for their specific context and take into account technological improvements or changes in industry since 2011. The background data sourced from the CAS RCEES 2018 Chinese localization should be used thoughtfully, considering its geographic and temporal relevance to the assessed process.
