How do titanium's strength and density compare with aluminum and iron?
Titanium is a lightweight, high-strength structural metal that offers a highly efficient strength-to-weight ratio compared to other common metals.12
Regarding density, pure titanium has a density of approximately 4.5 g/cm³. This places it midway between aluminum and iron; specifically, it is about half as dense as iron and less than twice as dense as aluminum.12
In terms of strength, while pure titanium is ductile and has relatively low strength, it is frequently used in alloy form to achieve much higher tensile strengths. These alloys are prized in aerospace and industrial applications because they maintain high strength and toughness while remaining lightweight. Its combination of low density and high strength makes it particularly effective for high-stress applications at temperatures up to 600 °C (1,100 °F).314562
