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.
The tensile strength of a material is the amount of pulling force that can be applied before it weakens and breaks. If something were suspended from a wire, the amount of weight that could be suspended before the wire snapped would be the wire's tensile strength.The two types of strengths don't always go hand in hand.he tensile strength of a material is the amount of pulling force that can be applied before it weakens and breaks.
