Aluminum by itself is a soft, pliable material. In order to make it more usable for a variety of products and applications, it goes through an alloying process where it is combined with other elements such as silicon, copper, magnesium, manganese, and zinc in order to enhance its strength and other properties.
For classification purposes, aluminum alloys are identified by four-digit numbers. The first digit identifies a general class, or series, characterized by its main alloying elements.
Alloys in the 1xxx series are the closest to pure, unalloyed aluminum. In fact, in this series, aluminum comprises about 99% of the chemical makeup. Because of the softness of this grade of aluminum, it has excellent weldability, but is not typically used for applications requiring high strength.
