What formula is used to calculate titanium tube weight?

Weight = (π ÷ 4) × (OD² − ID²) × Length × Density. OD is the outer diameter, ID is the inner diameter (OD − 2 × wall thickness), all in meters. Multiplying the cross-sectional area (m²) by the tube length (m) and alloy density (kg/m³) gives weight in kilograms.

What is the density of titanium used in the calculation?

Density depends on the grade. Common values: Grade 1 = 4510 kg/m³, Grade 2 = 4510 kg/m³, Grade 5 (Ti-6Al-4V) = 4430 kg/m³, Grade 9 = 4480 kg/m³, Grade 23 = 4430 kg/m³. This calculator uses the standard density for each selected grade.

What is the difference between outer diameter and wall thickness?

Outer diameter (OD) is the total outside dimension of the tube. Wall thickness is how thick the tube wall is. The inner diameter (ID) equals OD minus 2 × wall thickness. The calculator shows an error if the wall thickness is too large for the given OD.

What units are supported?

Diameter and wall thickness can be entered in mm, cm, or inches. Length can be entered in meters, mm, feet, or inches. All values are converted to meters internally before the calculation is performed.

Can I calculate weight for multiple tubes at once?

Yes. Enter the number of tubes in the Quantity field. The calculator shows both the per-tube weight and the total weight for the entire batch.

How does titanium tube weight compare to steel or aluminum?

Titanium (≈ 4510 kg/m³) is roughly 57% of the density of steel (≈ 7850 kg/m³) and about 1.67× denser than aluminum 6061 (≈ 2700 kg/m³). Titanium offers the best strength-to-weight ratio of the three, making it popular in aerospace and high-performance applications.

Formula Reference

W = (π / 4) × (OD² − ID²) × L × ρ

Where OD = outer diameter (m), ID = inner diameter = OD − 2×t (m), t = wall thickness, L = length (m), ρ = density (kg/m³), W = weight (kg).
