Calculating the Weight of 1 1/2 Inch Aluminum Square Tubing

Aluminum square tubing is a versatile material used in a wide range of applications, from construction and manufacturing to DIY projects. Knowing the weight of this tubing is crucial for design, structural calculations, and shipping estimations.

Understanding the Factors Affecting Weight

The weight of 1 1/2 inch aluminum square tubing is influenced by several key factors:

  • Material Grade: Aluminum comes in various alloys, each with different densities. Common grades used in tubing include 6061, 6063, and 6005.
  • Wall Thickness: Thicker walls mean more material and therefore heavier tubing.
  • Length: The weight increases proportionally with the length of the tubing.

Calculation Methods

There are several ways to calculate the weight of 1 1/2 inch aluminum square tubing:

  1. Using Density and Volume:

    • Determine the specific density of the aluminum alloy you're using.
    • Calculate the volume of the tubing (area of cross-section x length).
    • Multiply the volume by the density to get the weight.
  2. Using Online Calculators:

    • Many websites offer online calculators specifically designed for calculating the weight of aluminum tubing. These tools typically require you to input the material grade, wall thickness, and length.
  3. Referring to Manufacturer Data:

    • Aluminum tubing manufacturers often provide weight charts or specifications that list the weight per unit length for various tube sizes, grades, and wall thicknesses.

Example Calculation

Let's calculate the weight of a 1 1/2 inch aluminum square tubing made of 6061 alloy with a wall thickness of 0.125 inches and a length of 10 feet.

  • Density of 6061 Aluminum: 0.098 lb/in³
  • Cross-sectional Area: (1.5 in)² - (1.5 in - 2 x 0.125 in)² = 0.75 in²
  • Volume: 0.75 in² x 120 in (10 ft x 12 in/ft) = 90 in³
  • Weight: 90 in³ x 0.098 lb/in³ = 8.82 lbs


Knowing the weight of 1 1/2 inch aluminum square tubing is essential for accurate design, material purchasing, and transportation planning. By considering the factors mentioned above and utilizing the appropriate calculation methods, you can easily determine the weight of your tubing for any given scenario.
