Titanium tube

How to calculate the weight

The weight of tube is easily calculated. Simply multiply the appropriate alloy density by the calculation shown below of the required part.

Metric density (g/cm³) x (OD² - (OD - 2xT)²) x L x π / 4000 = weight
Example: 4.5 g/cm³ x (75 mm² - (75 mm - 2x1.0 mm)²) x 1m x π / 4000 = 1.046 kg
 
Imperial density (lbs/in³) x OD² - (OD - 2xT)²) x L x π / 4   weight
Example: 0.163 lbs/in³ x (3.5 in² - (3.5 in - 2x0.031 in)²) x 12in x π / 4 = 0.661 lbs

 

For imperial weight calculations certain measurements (fractions) need to be converted to decimal inches.

For an accurate calculation it is also important to allow for the rolled/drawn tolerances on section defined by the manufacturing specification – please contact us for details.

Density of titanium

The acknowledged density of titanium is 4.50 g/cm3 (0.163 lbs/in3). Depending on the alloy elements added to manufactured specifications this can vary between 4.4 and 4.9 g/cm3 (0.159 and 0.177 lbs/in3).
