T64 조건: Original supplier in-house performance interval; separately cast and casting-extracted specimens are included (p. 75). No wall thickness is stated for these ranges. Parenthetical values are separate casting minima at wall thickness ≤20 mm.

T6 조건: Original supplier in-house performance interval; separately cast and casting-extracted specimens are included (p. 75). No wall thickness is stated for these ranges. Parenthetical values are separate casting minima at wall thickness ≤20 mm.

화학 조성

검토를 마친 질량 백분율(wt%) 한계만 표시합니다. 비어 있는 한계는 다른 쪽 한계만 보고되었다는 뜻입니다.

Original branded supplier handbook p. 60 gives Alufont-52 / AlCu4Ti / 21 100. Detailed and summary tables are one PDF and one issuer. Ingot composition on pp. 76–77 uses mass %; single numbers are upper maxima, not composition midpoints. The performance ranges on pp. 60 and 79 do not specify wall thickness. Bracketed values are separate casting minima for wall ≤20 mm (p. 75). Fatigue summary ranges lack cycle count and stress ratio. P. 74 process-sheet wall classes and p. 101 general T6/T64 heat-treatment rows are retained separately; an exactly 8 mm wall is not assigned to a p. 74 class.
