Understanding Aluminum
Get To Know the Aluminum Alloy Series

In North America, the various aluminum alloys are classified and registered by the non-profit trade group The Aluminum Association. Currently there are 8 series of wrought aluminum alloys, each featuring a different alloying material, and designated a standard naming convention, from 1xxx through 8xxx. The first digit denotes the series, the second indicates which modification of the series the material is from and the last two are to simply list the material in the series.

  • 1xxx - the first series designates an alloy that is almost pure aluminum. This lightweight alloy contains more than 99% aluminum and is very pliable.
  • 2xxx - Copper is the primary alloying metal in 2000 series alloys. Between 2 and 10% of this alloy is copper, making it stronger and less ductile.
  • 3xxx - Manganese is added to aluminum to make 3000 series alloys. This results in moderate strength increases, and a particular usefulness at high temperatures.
  • 4xxx - Silicon aluminum alloys bring the melting point of the material down and increases the softness of the metal. This makes for a good filler material.
  • 5xxx - Magnesium alloyed with aluminum results in a material with extreme corrosion resistance. Very strong 5000 series sheet or plate is used in marine applications.
  • 6xxx - Magnesium AND silicon are added to aluminum to make the 6000 series. The result is a material ideal for extrusions, extremely weldable and perfect in structural uses.
  • 7xxx - Zinc is added to aluminum to create 7000 series materials. These are some of the strongest alloys available, and as a result, are often found in aircraft, aerospace, and sporting equipment.
  • 8xxx - Also often found in aircraft manufacturing, 8000 series alloys can be made up of materials not found in the other designations. Lithium is a good example, making a material that is less dense and very lightweight.

What Do The Differences in Temper Mean?
There are 5 Aluminum Alloy Temper Designations.

Aluminum is metal with so many different capabilities. This diversity of application is possible though the variety of tempering processes, and there's a system to decode what metal has undergone which process.

  • F - as fabricated. Can be understood to mean ‘semi-finished' and this material is intended to be further worked by additional processes down the line.
  • O - annealed. Wrought or cast product that has been worked using any number of processes, but that has also undergone high heat recrystallization processes.
  • H - strain-hardened. Non-heat-treatable wrought alloys, with increased strength due to room-temperature strain-hardening. May also indicate supplementary thermal treatments to maintain stabilization.
  • W - solution heat treated. An unstable condition only applying to alloys that experience ageing at room temperature, post-solution heat treatment.
  • T - thermally treated. The most common treatment for heated alloys, T indicates the material has undergone solution heat treatments followed by quenching and ageing, either by air or furnace.
