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.
Ductility and malleability are two aspects of the plasticity of solid materials. In metals, ductility and malleability are very high due to their ability to sustain large amounts of plastic deformations within the crystal structure.Platinum is the most ductile material, and gold is the most malleable material.Ductility. Ductility is the ability of a solid material to undergo tensile stress. This property of a solid material can be measured and describes the extent to which the solid material can be plastically deformed without fracture.It is often depicted by the ability of the solid to stretch into a wire when pulled at the ends.uctility vs Malleability. In common language, ductility refers to the ability to be deformed without losing toughness; that is pliable, but not brittle. Malleable means the ability to be hammered or pressed into shape without breaking or cracking.
