Density of Common Titanium Alloys
The density of titanium alloys generally ranges from approximately 4400 to 4800 kg/m3, depending on the specific alloy composition. This places titanium and its alloys among the lighter structural metals, making them attractive for various applications where a high strength-to-weight ratio is crucial.
The following table provides a comprehensive list of density values for different titanium alloys at standard room temperature (approximately 20°C or 68°F) and 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
