🔩 Aluminum Weight Calculator

Calculate aluminum weight based on dimensions and alloy type

How to Use This Calculator

1

Enter Length

Input the length of the aluminum piece in inches. For example, enter "12" for a 12-inch long piece.

2

Enter Width

Input the width of the aluminum piece in inches. For example, enter "12" for a 12-inch wide piece.

3

Enter Thickness

Input the thickness of the aluminum piece in inches. For example, enter "0.25" for 1/4 inch thickness.

4

Select Alloy Type

Choose the aluminum alloy type. 6061 is the most common. Click "Calculate Weight" to see the aluminum weight in pounds, kilograms, and grams.

Formula

Weight = Volume × Density

Volume = Length × Width × Thickness

Where: Aluminum density ≈ 169 lbs/cubic foot (0.098 lbs/cubic inch)

Example 1: 12" × 12" × 0.25" Aluminum Plate (6061)

Step 1: Convert to feet: 12" = 1 ft, 0.25" = 0.0208 ft

Step 2: Volume = 1 × 1 × 0.0208 = 0.0208 cubic feet

Step 3: Weight = 0.0208 × 169 = 3.52 pounds

Example 2: 24" × 48" × 0.125" Aluminum Sheet (6061)

Step 1: Convert to feet: 24" = 2 ft, 48" = 4 ft, 0.125" = 0.0104 ft

Step 2: Volume = 2 × 4 × 0.0104 = 0.0832 cubic feet

Step 3: Weight = 0.0832 × 169 = 14.06 pounds

Understanding Aluminum Density

Aluminum Density: Aluminum has a density of approximately 169 pounds per cubic foot (0.098 pounds per cubic inch). Most aluminum alloys have similar density, with slight variations. The calculator accounts for these variations based on alloy type.

Common Alloys: 6061 is the most common aluminum alloy, used for general-purpose applications. 7075 is a high-strength alloy used in aerospace. 2024 is used for aircraft structures. Different alloys have slightly different densities.

Tips for Best Results

  • Use Actual Dimensions: Always use actual aluminum dimensions, not nominal sizes
  • Measure Accurately: Use accurate measurements for precise weight calculations
  • Select Correct Alloy: Choose the correct alloy type for accurate density
  • Account for Holes: Subtract volume for holes or cutouts if significant
  • Check Material Sheets: Verify density values with material specification sheets

Frequently Asked Questions

What is the density of aluminum?

Aluminum has a density of approximately 169 pounds per cubic foot (0.098 pounds per cubic inch). Most aluminum alloys have similar density, with slight variations. The calculator accounts for these variations based on alloy type.

How do I calculate aluminum weight?

Weight = Volume × Density, where Volume = Length × Width × Thickness. For example, a 12" × 12" × 0.25" aluminum plate = (1 × 1 × 0.0208) × 169 = 3.52 pounds.

What is the most common aluminum alloy?

6061 is the most common aluminum alloy, used for general-purpose applications. It's strong, corrosion-resistant, and easy to machine. The calculator defaults to 6061 for convenience.

How much does a 4x8 aluminum sheet weigh?

It depends on thickness. For 0.125" thick 6061 aluminum: (4 × 8 × 0.0104) × 169 = 5.88 pounds. For 0.25" thick: (4 × 8 × 0.0208) × 169 = 11.76 pounds. The calculator shows exact weight based on your dimensions.

Can I calculate weight for different aluminum alloys?

Yes! Select the aluminum alloy type from the dropdown (1100, 3003, 5052, 6061, 6063, 7075, 2024). The calculator uses the correct density for each alloy type.

How do I convert aluminum weight to cost?

Multiply the weight (in pounds) by the price per pound. For example, if aluminum costs $2.50 per pound and you have 10 pounds: 10 × $2.50 = $25.00. Always check current market prices with your supplier.
