Galena Mineral | Uses And Properties

Galena Mineral | Uses And Properties

Galena tarnishes to a dull gray. Because lead is a primary element in galena, the mineral has a high specific gravity (7.4 to 7.6) that is immediately noticed when picking up even small pieces. Galena is soft with a Mohs hardness of 2.5+ and produces a gray to black streak. Crystals are common and they usually are cubes, octahedrons, or ...

Specific Gravity Of Metals Table

Specific Gravity Of Metals Table

For example, beryllium has a specific gravity (sg) of 1.84 (1840 kg/m³). As specific gravity is just a comparison, it can be applied across any units. The density of pure water is also 62.4 lbs/ft³ (pounds per cubic foot) and if we know that a sample of aluminum has a sg of 2.5 then we can calculate that its density is 2.5 x 62.4 = 156 lbs/ft³.
