How To Measure The Thickness Of Aluminum Foil?

Aluminum foil is an aluminum product with a relatively thick foil thickness obtained by rolling a thick aluminum alloy plate. The thickness of aluminum foil is usually less than 0.5mm. How to measure the thickness of such a thin aluminum foil?

There are several ways to measure the thickness of aluminum foil, one of the most commonly used methods is based on the calculation of weight and density.

Tools needed to calculate foil thickness

• Ifoyile yeAluminiyam
• Precise electronic scale (capable of measuring to the precision of grams)
• Pythagoras flask or graduated cylinder (to measure the area of ​​foil)
• Vernier caliper (optional, to measure thickness directly)
• Ruler (to measure the length and width of foil)

Method 1: Calculate thickness based on weight, area and density

Density of aluminum: 2.7 g/cm³

Steps

1. Weighing: Use an accurate electronic scale to weigh the aluminum foil, making sure to record the weight in grams (g). Write down the mass of the foil 𝑚

2. Measure the area of ​​the foil: Spread the foil flat, measure the length and width of the foil with a ruler, and calculate the total area of ​​the foil 𝐴:A (in square centimeters cm²).
Area formula: A=length×width

Calculate volume: Use the density formula for aluminum to calculate the volume of the foil
𝑉:V (in cubic centimeters cm³).
Volume formula: 𝑉=𝑚/𝜌
ρ is the density of aluminum, 2.7 g/cm³.

Calculate volume: Use the density formula for aluminum to calculate the volume of the foil
𝑉:V (in cubic centimeters cm³).
Volume formula: 𝑉=𝑚/𝜌
ρ is the density of aluminum, 2.7 g/cm³.

𝑡 is equal to volume divided by area.
Thickness formula:

𝑡=𝑉/𝐴

Method 2:Use a caliper or digital vernier caliper

Prepare tools: prepare a caliper or digital vernier caliper with high accuracy.
Place aluminum foil: Place the aluminum foil on a flat and stable surface to ensure that it is flat and wrinkle-free.
Measurement operation: Align one end of the caliper with the edge of the aluminum foil and gently press the other end on the aluminum foil to ensure that the caliper is in full contact with the aluminum foil and vertical.
Read the result: Read the measured value on the caliper, which is the thickness of the aluminum foil.

Method 3:Use an aluminum foil thickness gauge

Choose a thickness gauge: Choose a thickness gauge suitable for aluminum foil measurement to ensure that its accuracy and measurement range meet the requirements.
Calibrating the instrument: Calibrate the thickness gauge before use to ensure the accuracy of the measurement results.
Measurement operation: Gently press the probe of the thickness gauge on the aluminum foil to ensure that the probe is in full contact with the aluminum foil.
Read the result: The thickness value of the aluminum foil will be displayed on the display of the thickness gauge, and you can read it directly.

Method 4:Use X-ray fluorescence thickness measurement method

Prepare equipment: X-ray fluorescence thickness gauge and related standard samples.
Place aluminum foil: Place the aluminum foil and the standard sample in the X-ray instrument at the same time.
Measurement operation: After the X-ray passes through the aluminum foil and the standard sample, it is excited by the phosphor on the phosphor screen to produce fluorescence.
Calculate thickness: Measure the fluorescence intensity of the phosphor on the phosphor screen, and calculate the thickness of the aluminum foil based on the relationship between the fluorescence intensity and thickness of the standard sample.
