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.
Iron requires considerably more effort to pound into a sheet and is therefore less malleable. Yet, both are metals. In contrast, non-metallic elements, such as carbon or sulfur, shatter into pieces when hammered. Malleability is a valuable property because it allows metals to be shaped into useful forms.Pure gold is the most malleable metal. Silver, aluminum, lead, tin, and copper are also very malleable. Heating usually increases malleability.For instance, zinc, at standard temperatures is brittle, but becomes malleable at temperatures between 248Â°F (120Â°C) and 302Â°F (150Â°C).ron requires considerably more effort to pound into a sheet and is therefore less malleable.
