WebMeasuring the Ductility of Metals Web9 jun. 2024 · A material with high ductility means it’s more likely to deform (but not break!). Low ductility indicates that it’s brittle and will fracture easily under a tensile load. Elongation at break also called “fracture strain” or “tensile elongation at break” is the percentage increase in length that material will achieve before breaking.
