A pure white metallic element used as an alloy to enhance corrosion resistance. Native silver often has variable admixtures of other metals, such as gold, copper and sometimes platinum. Silver is used extensively in alloys used to make containers for the food and chemical industries, where other metals fail to withstand corrosion. Atomic weight, 107.88; specific gravity at 20°C (68°F), 10.5; melting point, 960°C (1760°F); Brinell hardness 37.
