The shipment volumes of secondary aluminum alloys in sand and permanent mold methods are projected to increase steadily from 60.6 thousand metric tons in 2024 to 72.43 thousand metric tons in 2028. This represents a consistent growth trend with a compound annual growth rate (CAGR) of approximately 4.6% over these five years. Year-on-year percentage growth maintains a range of 5-5.5% as shipment volumes expand. Unfortunately, the data prior to 2024 isn't provided, so comparisons with actual 2023 shipments remain unspecified.

Future trends to watch:

Technological advancements in production methods might influence alloy demand.
Environmental policies could affect material preferences, emphasizing sustainable production.
Market development in sectors like automotive and construction, key consumers of aluminum alloys, could drive further volume increases.
