AI overview
Ductility is the ability of a material to stretch and deform without breaking when pulled or stressed. It matters because ductile materials like certain aluminum alloys can bend and change shape significantly before fracturing, while materials with low ductility—like some cast irons—break more suddenly with less deformation.
