Aluminum Hex Bar Weight Calculator
Calculate the weight of Aluminum Hex Bar by entering your dimensions. The density of Aluminum is 0.0975 lb/in³ (2699 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
Aluminum stock for machining and fabrication ships in several common alloys: 6061-T6 is the structural workhorse for plates, brackets, and tooling fixtures; 7075-T6 trades weldability for higher yield strength and is preferred in aerospace ribs and high-load shafts; 5052-H32 dominates marine and sheet-metal work because of its corrosion resistance and formability. Specify the alloy explicitly on the purchase order — distributors will quote on generic '6061' if you let them, which can be 6061-T6511 extrusion that machines very differently from cold-finished 6061-T6 plate.
Hex bar is six-sided stock with standard across-flats sizes that match common wrench openings — used to manufacture bolts, nuts, valve bodies, fittings, and any part that needs a wrench-grip surface as-machined. Cold-drawn hex bar in 12L14 leaded steel, 304 stainless, or C360 brass is the Swiss-turning workhorse for high-volume fastener production. Specify across-flats (AF) dimension, not across-corners, because AF maps directly to the wrench size users will reach for. Hex stock costs more per pound than round but eliminates a complete six-face milling operation.
Common Applications
Aluminum Hex Bar 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 Aluminum. 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.
