History of Electrum. This gold-silver alloy has a long history of being used by humans. It was used for different purposes since third millennium BC. However, the variation in the gold and silver contents of this alloy made it difficult to decide the value of each coin.
To measure a material's ductility, the tester typically takes a measurement of the material's tensile strength. Tensile strength examines how far the material can stretch without breaking. This ability is similar to malleability, though they each have a slight difference. Instead of measuring tensile strength, or essentially how far the metal can stretch, malleability measures how much pressure a material can take without breaking or cracking.
Difference Between Ductility and Brittleness â¢ Ductility is the ability of a material to withstand tensile force when it is applied upon it as it undergoes plastic deformation â¢ Brittleness is the opposite of ductility as it refers to the ability of materials to break into pieces upon application of tensile force without any elongation or plastic deformation
