Calibre de aluminio, commonly referred to as the “indicador” de aluminio, is a measurement of the thickness or diameter of aluminum sheet or wire. It is a common method of specifying the thickness of aluminum materials and is used in a variety of industries, incluyendo la construcción, fabricación, and metalworking.

In the United States, aluminum specifications are usually expressed in numerical values, ranging from lower numbers to higher numbers. The higher the gauge number, the thinner the aluminum sheet or wire. En cambio, lower gauge numbers indicate thicker aluminum material. Por ejemplo:
12 gauge aluminum is thicker than 16 calibre de aluminio.
18 gauge aluminum is thinner than 14 calibre de aluminio.

What is the thickness indicated by the aluminum gauge? Take a 12 gauge aluminum sheet as an example. How many inches is 12 calibre de aluminio?
El espesor de 12 gauge aluminum plate is approximately 0.0808 pulgadas o 2.05 milímetro.
