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.
Ultimate tensile strength is also known as tensile strength or the ultimate. The ultimate tensile strength (UTS) is a material's maximum resistance to fracture. It is equivalent to the maximum load that can be carried by one square inch of cross-sectional area when the load is applied as simple tension. The UTS is the maximum engineering stress in a uniaxial stress-strain test.
