T4 조건: Original supplier in-house performance intervals (handbook p. 75); separately cast and casting-extracted samples are included. No wall thickness is stated for these ranges. Parenthetical values in the same row are casting minima at wall thickness ≤20 mm and are stored separately.

T6 조건: Original supplier in-house performance intervals (handbook p. 75); separately cast and casting-extracted samples are included. No wall thickness is stated for these ranges. Parenthetical values in the same row are casting minima at wall thickness ≤20 mm and are stored separately.

Official branded supplier record. The 2016 handbook pp. 76–77 gives ingot composition in mass %; single numbers are upper limits, not midpoints. The chemical designation is printed AlCu4TiMg in the chemistry table but AlCu4MgTi in the mechanical summary; identity is tied to the distinct Alufont-47 brand and numerical designation 21000, without assuming other equivalences. Mechanical ranges on p. 79 are supplier in-house performance ranges; bracketed figures are distinct casting minima for walls up to 20 mm (p. 75). No thickness is assigned to the performance ranges. Fatigue ranges on p. 79 have no cycles or stress ratio in that summary, so they are not published as standard fatigue endpoints.
