T1Not specified160–200220–2805–10

T1 condition: Original-supplier T1 self-aged performance range. Wall thickness, test specimen size, test temperature and precise ageing duration are not reported for this row.

Chemical composition

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

Original-supplier branded Castadur-50 / AlZn5Mg, not generic AlZn5Mg. The 2015 overview, 2016 handbook, REACH technical information and current product page are one issuer, not independent votes. The T1 sand-cast mechanical row does not state wall thickness, specimen size, test temperature or precise self-ageing duration. The F application sheet is a cover page with no numerical table; it does not establish F-state mechanical values. Blank gravity-die shrinkage and fatigue cells remain absent. REACH ingredient-disclosure ranges are not ingot specification limits.
