The key idea is how much stress a metal can endure before it deforms or fails. Strength is exactly that: it quantifies the material’s ability to resist deformation when a load is applied, meaning a higher-strength metal will deform less or not yield until a larger load is reached. Elasticity, on the other hand, is about how deformation is reversible—if the load is removed, the material returns to its original shape (within the elastic range). Hardness describes resistance to surface indentation, not how the entire material behaves under a load. Plasticity refers to permanent deformation after yielding. So, when you’re assessing a metal’s resistance to deformation under load, strength is the most relevant property.
