Titanium Round Rod Weight Calculator
Calculate the weight of Titanium Round Rod by entering your dimensions. The density of Titanium is 0.161 lb/in³ (4456 kg/m³). Use this calculator for quick stock weight estimates in your CNC machining projects. Accurate weight calculations are essential for shipping quotes, material cost estimation, fixturing load analysis, and structural design verification. The theoretical weight formula assumes a uniform cross-section and standard alloy density; actual weights may differ slightly by grade and mill tolerance. Weight data is calculated using the standard volumetric formula multiplied by the material density constant shown above.

Sourcing and Use Notes
Grade 2 commercially pure titanium is the corrosion-resistant workhorse for chemical and marine fittings, heat exchangers, and medical implants — 240 MPa yield, fully weldable, and roughly 60% the strength-to-weight ratio of Grade 5. Grade 5 (Ti-6Al-4V) alpha-beta alloy is the structural titanium standard at 830 MPa yield, used for aerospace fasteners, racing components, and orthopedic implants. Titanium is biocompatible but galvanically active — never assemble titanium parts dry against aluminum or zinc without insulating sleeves, or aggressive crevice corrosion will start within months in damp environments.
Round bar is the universal turning stock — used for shafts, dowels, pins, threaded rod blanks, and any rotationally symmetric part. Cold-drawn round bar typically holds h9 concentricity (about ±0.05 mm on 25 mm diameter), which is the right starting point for parts that will be finish-turned. For ground-and-polished shaft applications (linear motion shafting, hydraulic cylinder rods) buy h7 ground bar to save a turning operation. Hot-rolled round is cheaper but loose on roundness and surface finish — appropriate only for stock that will be fully machined on every diameter.
Common Applications
Titanium Round Rod is a standard stock form used in structural frames, machine bases, brackets, and fabricated components. Its consistent cross-section simplifies weight-per-foot calculations and material takeoffs for procurement and shipping cost estimates. Engineers and machinists rely on theoretical weight data during the quoting and planning stages before final parts are produced. For large orders or weight-critical designs, request certified mill test reports (MTRs) to confirm actual density and alloy composition.
Sourcing and Weight Tolerance Note
This weight is based on the theoretical density of Titanium. Mill tolerances (ASTM A6 allows ±2.5% on cross-sectional area for structural shapes) and surface treatments (anodizing, plating, painting) may add 1–3% to actual shipped weight. Order 5–10% material overage to account for saw kerfs and offcuts. Always verify actual material density with your supplier's material test report (MTR) for critical structural or load-bearing applications. Compare weights across materials using the comparison table above to make informed material selection decisions for your project.
