DENSITY OF MATERIALS



The density of a material is defined as material mass per unit volume and designated by the symbol ρ (rho). The SI unit of density is kg / m3 and U.S. customary unit of density is lb/ft3. Density is an important characteristic property of a material and varies with temperature and pressure.

Room temperature density values for some of the common materials including aluminum, steel, bronze, iron, brass, concrete, copper, gold, silver, invar, magnesium, nickel, timber, titanium and zinc are given in the following materials density chart.
