Density of Materials – Metals, Alloys & Construction Materials

Density (ρ) is defined as the mass (m) per unit volume (V) of a material and is one of the most important physical properties used in engineering and industrial design. It directly influences weight estimation, structural integrity, material selection, and piping calculations. The following table presents the density of commonly used metals, alloys, and construction materials in both SI units (kg/m³) and Imperial units (lb/ft³). These values serve as reference data and may vary depending on composition, grade, and manufacturing process. For accurate design purposes, consult relevant standards or supplier specifications.
