What formula is used to calculate titanium beam weight?

The cross-sectional area is computed as A = 2 × (bf × tf) + (h − 2 × tf) × tw, where bf = flange width, tf = flange thickness, h = total height, and tw = web thickness. Weight = Area × Length × Density. This is the standard analytical formula for I-beam and H-beam sections used in structural engineering.

What density does the calculator use for titanium?

The default is commercially pure titanium Grade 2 at 4510 kg/m³. Ti-6Al-4V (Grade 5), the most common titanium alloy, uses 4430 kg/m³. You can select other alloys from the dropdown or enter a custom density.

What is the difference between an I-beam and an H-beam in titanium?

Both share the same cross-section shape — two flanges connected by a web. An I-beam has a relatively narrow flange, while an H-beam (wide-flange) has flanges nearly as wide as the section height. This calculator covers both — just enter the correct dimensions for your section.

Can I calculate weight for multiple beams?

Yes. Enter the quantity in the Quantity field and the tool reports total weight for all beams as well as the per-beam weight for reference.

Does this tool support imperial units?

Yes. All cross-section dimensions can be entered in millimeters, centimeters, or inches, and the length can be entered in meters, millimeters, feet, or inches. Unit conversions are handled internally.

Why is titanium so much lighter than steel for the same beam dimensions?

Titanium has a density of roughly 4500 kg/m³ compared to 7850 kg/m³ for carbon steel — about 43% lighter. This makes titanium beams significantly lighter for the same geometry, which is why they are favored in aerospace, marine, and high-performance applications despite a higher material cost.
