Chemical composition
Only reviewed weight-percent bounds are listed. A blank bound means only the other threshold was reported.

The sheet lists Al balance, Si 25%, Cu 4%, Mg 1%, but gives no composition limits or tolerance; these are not specification ranges. Relative density is a lower bound measured optically on an LPBF specimen, not a bulk density substitute. Mechanical and roughness values depend on heat treatment, print direction, surface processing and other conditions.
