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.
Ultimate tensile strength (UTS), often shortened to tensile strength (TS) or ultimate strength, is the maximum stress that a material can withstand while being stretched or pulled before failing or breaking.ensile strength is defined as a stress, which is measured as force per unit area. For some non-homogeneous materials (or for assembled components) it can be reported just as a force or as a force per unit width.
