What is 040 aluminum sheet?

040 aluminum sheet refers to an aluminum sheet that has a thickness of 0.04 inches. In aluminum sheet specifications, the thickness is often expressed in gauge, inches, or millimeters. In this case, “040” indicates the thickness in inches, where 1 gauge is approximately equal to 0.001 inch. Therefore, 040 aluminum sheet is fairly thin, commonly used in applications where lightweight and moderate strength are required, such as in crafting, signage, or light structural components.

.040 aluminum sheet thickness in mm

To convert the thickness of 0.040 inches aluminum sheet to millimeters, you can use the conversion factor:

1 inch = 25.4 millimeters

So, for 0.040 inches:

0.040 inches * 25.4 millimeters/inch = 1.016 millimeters

Therefore, 0.040 inches of aluminum sheet thickness is approximately 1.016 millimeters.
