Titanium is a lightweight, strong and durable metal. It has a specific gravity of 4.5 to 4.7, which means that it is four to seven times as heavy as water. The exact weight varies depending on the type of titanium and how it’s manufactured.
The most common grades of titanium are alpha (ASTM F67) and beta (ASTM F68). Alpha titanium has a specific gravity of 4.5 and beta titanium has a specific gravity of 4.7. Both grades are used in aircraft construction and other applications where strength and light weight are important factors in choosing a material for fabrication or manufacturing processes.
Titanium alloys vary in specific gravity from about 3 – 5 grams per cubic centimeter (g/cm3). The alloy with the highest density is Titanium 6-4, which has a specific gravity of 5 g/cm3 at room temperature (20°C). This alloy has excellent strength-to-weight ratio, but is difficult to machine because it tends to work harden during machining operations such as turning or milling due to its high hardness.
