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.
Malleability is the ability of materials to deform easily under compressive stress. This can be often characterized as materials ability to form thin sheets by hammering or rolling. On the other hand, Ductility is the ability of materials to deform easily under tensile stress.
Definition - What does Tensile Strength mean? Tensile strength is the ability of a material to withstand a pulling (tensile) force. It is customarily measured in units of force per cross-sectional area. This is an important concept in engineering, especially in the fields of material science, mechanical engineering and structural engineering. The ability to resist breaking under tensile stress is one of the most important and widely measured properties of materials used in structural applications.
