Kinds of aluminum alloys

The 1xxx are high purity aluminum, at least 99%. Used in applications in which the mechanical characteristics are not the most important properties, but others as corrosion resistance or electrical conductivity are.

The 2xxx alloy with copper, which greatly enhances its mechanical strength.

The 6xxx are allow with magnesium and silicon. They are the 6161 or 6063 of many parts, basically because they are easily shaped and have good mechanical properties.

The 7xxx are mainly alloyed with zinc. In this series, the most typical in bikes is the 7005. Aluminums of this series have excellent mechanical properties, although the forming is not generally as good as the 6xxx.

The 7075 has an extraordinary strength, but is not used for complicated frame tubes, only for more or less simple forms like handlebars or dishes.

The corrosion resistance is generally worse than other series, although for a bike it tends to be an important factor.
