How to Find the Thickness of Aluminum Foil?

When you pick up a roll of aluminum foil from the supermarket shelf, have you ever wondered about its thickness? While most packaging provides this information, there may be times when you need to verify the specifications or simply satisfy your curiosity. Especially, as a buyer, knowing the thickness of aluminum foil can help you make informed purchasing decisions, ensuring you get the right product for your needs.

This article, Zhengzhou Eming Aluminium Industry, as a renowned aluminium foil manufacturer and supplier, will guide you through a simple method to calculate the thickness using basic measurements and calculations.

Generally, the width of household aluminum foil rolls is 30cm or 45cm. For the purpose, let’s work with a 30cm aluminum foil roll. Finding the thickness involves a simple three-step process:

Step 1: Cutting the Aluminum Foil

Firstly, you need to cut a section of the aluminum foil that is easy to handle and accurate enough for measurement. Given that aluminum foil is lightweight, it is best to cut a longer piece to ensure accuracy. Therefore, take your 30cm aluminum foil roll and cut a 100cm section from it.

Step 2: Weighing the Aluminum Foil

Next, you need to determine the mass of your aluminum foil segment. For ease of weighing, crumple the 100cm section into a ball. Using a precise kitchen scale, weigh the crumpled ball to find it weighs 12 grams.

Step 3: Finding the Thickness of Aluminum Foil

Now comes the mathematical part. We will use the formula: m=pV

Where m represents mass (which we have as 12g), p represents density (the density of aluminum foil is about 2.7g/cm³), and V represents volume. The volume V can be expressed as: V=L×W×H.

Here, L is the length (100cm), W is the width (30cm), and H is the height, which in this case refers to the thickness of the aluminum foil.

Rearranging the formula to solve for H (thickness), we get:

H= m/(p × L × W) = 12g/(2.7 g/cm³ × 100cm × 30cm) ≈ 0.0015 cm or 15 μm

How to find the thickness of aluminum foil is crucial, as it affects heat conduction and the durability.

By following these simple steps, you can now easily find the thickness of aluminum foil.
