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.
Tensile Strength Calculator. Tensile strength is the maximum amount of force taken by a material before its failure. (i.e.,) The maximum force taken by a rope to point till it breaks is the tensile strength of the force. It is measured with units : Newtons/Millimeter Squared (N/mm2), Megapascals (MPa), KiloPascals(KPa), Pounds Per Square Inch(Psi), Thousands of Pounds Per Square Inch (Ksi).
