1000 Series Aluminum Alloys

1000 Series Aluminum is a soft and very ductile material, with excellent workability. This material is well suited for applications that involve severe forming because it work hardens more slowly during the forming process. 1000 Series Aluminum takes extremely well to welding and is the most weldable of all aluminum alloys.

Description

1000 Series has minimum of 99% aluminum with no major alloying additions. These compositions are characterized by excellent corrosion resistance, high thermal and electrical conductivity, low mechanical properties and excellent workability. These alloys are non-heat treatable. The most common type is A91100 which is commercially pure aluminum. It is soft and very ductile, having excellent workability. Well suited for applications involving severe forming as it work hardens more slowly during forming. It is the most weldable of all aluminum alloys.

The aluminum content for unalloyed aluminum not made by a refining process is the difference between 100.00 percent and the sum of all other analyzed metallic elements present in amounts of 0.010 percent of more each, expressed to the second decimal before determining the sum. For alloys and unalloyed aluminum not made by a refining process, when the specified maximum limit is 0.XX, an observed value or a calculated value greater than 0.005 but less than 0.010% is rounded off and shown as" less than 0.01%".
