Calculating aluminum weight?
Select your aluminum shape and enter its dimensions to find the total weight based on industrial density standards.
About this calculator
Overview
Aluminum is favored in construction and aerospace for its high strength-to-weight ratio. While its density is roughly one-third of steel, variations in alloy composition can slightly affect the total weight. This calculator provides precision estimates for the most common structural shapes.

Pro Tips
For hollow tubes, remember that the thickness applies to the walls—internal diameter is Outer Diameter minus twice the thickness.
If you're buying in bulk, always account for a 2-3% variance in weight due to manufacturing tolerances.
6061 is the most common 'multipurpose' alloy for structural projects due to its good weldability and corrosion resistance.

Fun Facts
"Aluminum is the most abundant metal in the Earth's crust, making up about 8% of its total weight."
"7xxx series aluminum (like 7075) is almost as strong as many steels but remains much lighter."
"Recycling aluminum saves about 95% of the energy required to produce it from raw ore (bauxite)."
