The sheet lists Si 35% and Al balance, but no certified chemistry limits; neither is registered as a specification range. The AM sheet is distinct from ordinary S220. Absolute density carries the printed ±5% tolerance. Mechanical data on p. 2 require stress relief 4 h at 500°C, a turned vertical Z-direction test specimen, and the manufacturer’s non-guarantee statement; they are withheld along with surface-roughness and other table cells.
Physical and thermal properties
