Chemical composition

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

Original-supplier branded Anticorodal-72 grade, not a generic AlSi7Mg0.6 equivalence. Main ranges do not state wall thickness; p. 75 scopes parenthetical casting minima to walls ≤20 mm. P. 78 fatigue ranges have no cycle count or stress ratio and are observations, not protocol-qualified fatigue. REACH ingredient disclosures are not ingot specifications. The illustrated low-pressure casting is an example, not a fourth mechanical row.

supplier qualitative characteristicsSupplier describes very good mechanical properties, outstanding corrosion resistance, very good weldability and machining, and higher Mg with higher strength/hardness but lower elongation than Anticorodal-70. These are supplier qualitative comparisons, not normalized cross-grade test values.
supplier casting examplesThe supplier illustrates a low-pressure fine-cast landing-flap suspension and a sand/gravity-cast anchor. The illustrated low-pressure part is not a separate mechanical test interval.
