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

Chemical composition

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

Unifont-94 is a supplier-branded grade, not a generic AlZn10Si8Mg equivalence. Unifont-90 and -94 have distinct composition limits and casting routes despite the same chemical denomination. The 2015 overview, 2016 handbook and current product page are one issuer, not independent votes. The supplier-linked Unifont-94 technical PDF names Unifont-90 inside and is excluded. The T1 mechanical rows do not give wall thickness, test temperature, specimen size or exact ageing duration. Parenthetical casting minima, where printed, apply only to walls up to 20 mm. Fatigue cycle count and stress ratio are not reported.
