The density of non-ferrous metals
Density of aluminum in comparison with the density of other light metals:

aluminum: 2,70 g / cm3
titanium: 4,51 g / cm3
magnesium: 1,74 g / cm3
beryllium: 1,85 g / cm3
Density of material
unit of measurement
Density of aluminium and any other material – it is a physical quantity, determining the mass ratio of the material to the occupied volume.

The unit of density measurement in the SI dimension adopted kg / m3.
For the density of aluminum is often used more visual dimension g / cm3.
aluminum Density kg / m3 thousandfold, than g / secm3.

Specific gravity
To estimate the amount of material per unit volume is often used such a system does not, but more visual unit as "proportion". Unlike density specific gravity is not an absolute unit of measurement. The thing is, it depends on the magnitude of the gravitational acceleration g, which varies depending on the location on Earth.

Density dependence on temperature
The density of the material depends on the temperature. Typically, it decreases with increasing temperature. On the other hand, specific volume - volume per unit mass - increases with increasing temperature. This phenomenon is called thermal expansion. It is usually expressed as a coefficient of thermal expansion, which gives the change in length per degree of temperature, for example, mm / mm / ° C. Change in length is easier to measure and use, than the change in volume.

specific volume
The specific volume of the material – this value, inverse density. It indicates the amount of mass and per unit volume is of dimension m3/kg. According to the specific volume of material it is convenient to observe during the heating-cooling change the density of materials.

The figure below shows the change in the specific volume of various materials (pure metal, alloy and amorphous material) with increasing temperature. Flat areas schedules - is the thermal expansion of all types of materials in the solid and liquid state. When pure metal melts, there is a jump in the increase in specific volume (decrease in density), the alloy melting - rapid increase as its melting temperature range in. Amorphous materials upon melting (at the glass transition temperature) increase their coefficient of thermal expansion [2].
