Many generic metal charts use an average density of 0.098 lb/in³. However, high-zinc aerospace 7075 aluminum weighs 0.1015 lb/in³—a 4.1% increase over 5052 alloy (0.0968 lb/in³). In multi-ton machining orders or aircraft freight, this variance causes costly weight budget overruns.
Machine shops ordering thick aluminum tooling plate often underestimate batch shipping weight, resulting in rejected pallet deliveries or forklift tip hazards. Our calculator instantly tallies total piece quantities into precise net shipment weight.
CNC machinists must estimate raw block costs prior to chip evacuation. By selecting round bar or rectangular plate dimensions, estimators calculate starting raw material outlay in seconds before programming milling toolpaths.
Engineers replacing carbon steel weldments with aluminum need verified weight savings metrics for vehicle payload and fuel efficiency modeling. Our engine provides immediate side-by-side equivalent steel weight comparisons.
Select flat sheet/plate, solid round bar, extruded round tube, square bar, or hex bar from the shape selector.
Select 6061-T6, 5052 marine grade, 7075 aerospace, 2024, or 3003 to automatically apply certified ASTM mill densities.
Enter thickness, width, length, outer diameter, or wall thickness in fractional or decimal inches or metric millimeters.

Aluminum is renowned in structural and aerospace engineering for its extraordinary strength-to-weight ratio. With an atomic mass of 26.98 and face-centered cubic (FCC) crystal lattice, pure aluminum has a specific gravity of 2.70. Alloying elements such as copper, zinc, magnesium, and silicon alter this density:
Density: 0.0975 lb/in³ (2.70 g/cm³). The universal structural alloy. Excellent weldability, high corrosion resistance, and 45 ksi tensile strength.
Density: 0.0968 lb/in³ (2.68 g/cm³). The marine champion. Superior saltwater pitting resistance, excellent cold formability for sheet metal hulls.
Density: 0.1015 lb/in³ (2.81 g/cm³). Aircraft & defense alloy. Yield strength over 73 ksi, comparable to structural steel at one-third the weight.
Pre-calibrated densities for 6061-T6 (0.0975 lb/in³), marine-grade 5052 (0.0968 lb/in³), aerospace 7075 (0.1015 lb/in³), 2024, and 3003 alloys.
Calculates flat sheets, tooling plate, solid round bar, extruded round tubing, square bar, and hexagonal bar geometries.
Instantly quantifies equivalent carbon steel weight, demonstrating the verified ~65.5% weight reduction for structural engineering.
Computes raw metal stock costs per piece and total batch outlay based on current supplier price per pound or kilogram.
To calculate the weight of an aluminum plate: multiply Length (in) x Width (in) x Thickness (in) x Density (lbs/in³). For standard 6061-T6 aluminum (density 0.0975 lb/in³), a 48" x 96" sheet of 1/4" (0.25") plate weighs: 48 x 96 x 0.25 x 0.0975 = 112.32 pounds.
Standard 6061-T6 aluminum has a density of 0.0975 lb/in³ (2.70 g/cm³). Marine-grade 5052 aluminum has a density of 0.0968 lb/in³ (2.68 g/cm³). High-strength 7075-T6 aerospace aluminum is slightly denser at 0.1015 lb/in³ (2.81 g/cm³), while 2024-T3 aircraft alloy has a density of 0.1004 lb/in³ (2.78 g/cm³).
Aluminum weighs approximately one-third (about 34.5%) of carbon steel of the exact same geometric volume. Mild carbon steel has a density of 0.2833 lb/in³ (7.85 g/cm³), whereas 6061 aluminum is 0.0975 lb/in³ (2.70 g/cm³). A steel plate weighing 100 lbs would weigh approximately 34.4 lbs in 6061 aluminum.
To find aluminum tube weight: calculate cross-sectional metal area by multiplying pi x (Outer Diameter - Wall Thickness) x Wall Thickness, then multiply by tube Length and alloy density. Formula: Weight = pi x (OD - t) x t x Length x Density.
As an industry rule of thumb, 1-inch thick 6061 aluminum plate weighs approximately 14.04 pounds per square foot (0.0975 lb/in³ x 144 in²). For any thickness, simply multiply 14.04 by the thickness in inches to get weight per square foot: for example, 1/4" (0.25") plate weighs 14.04 x 0.25 ≈ 3.51 lbs per square foot.
