What formula is used to calculate titanium round bar weight?

The formula is: Weight = (π ÷ 4) × Diameter² × Length × Density. The diameter and length are converted to meters, multiplied to get volume in m³, then multiplied by the titanium grade density (kg/m³) to get weight in kilograms.

What is the density of titanium?

Commercially pure titanium (Grade 1 and 2) has a density of approximately 4510 kg/m³ and 4507 kg/m³ respectively. The widely used Ti-6Al-4V (Grade 5) alloy is slightly less dense at 4430 kg/m³ due to the aluminum and vanadium content.

Does this support both metric and imperial units?

Yes. Diameter can be entered in mm, cm, or inches. Length can be entered in meters, mm, feet, or inches. All values are converted internally before calculation.

Can I calculate the total weight for multiple bars?

Yes. Enter the number of bars in the Quantity field and the calculator will show both the per-bar weight and the total weight for all bars combined.

What is the difference between Grade 2 and Grade 5 titanium?

Grade 2 is commercially pure titanium (density 4507 kg/m³) and is used where corrosion resistance and formability are important. Grade 5 (Ti-6Al-4V) is an alloy with higher strength and slightly lower density (4430 kg/m³), making it the most widely used titanium alloy in aerospace and medical applications.

Why is titanium lighter than steel but still considered heavy?

Titanium (≈4507 kg/m³) is about 56% the density of steel (≈7850 kg/m³), making it significantly lighter for the same volume. However, it is still roughly 1.67 times denser than aluminum (≈2700 kg/m³), so titanium bars are heavier than equivalent aluminum bars.
