The thickest aluminum foil that is commonly available for household use is around 0.03-0.04 millimeters thick, also known as heavy-duty aluminum foil.
However, there are thicker aluminum foils available for specialized industrial applications. For example, some heavy-duty industrial aluminum foil can be up to 0.2 millimeters thick or more.
The thickness of aluminum foil can also be measured in mils, with one mil equal to 0.001 inches or approximately 0.0254 millimeters. The thickness of aluminum foil can impact its strength and durability, as well as its ability to withstand high temperatures or resist tearing or punctures.
