6000 & 7000 Series Aluminum Alloys

6000 & 7000 Series Aluminum Alloys

Alloys in this group have magnesium and silicon as the major alloying elements.

6000 Series

Alloys in this group have magnesium and silicon as the major alloying elements. They are moderate strength alloys which is achieved by either heat treating or cold working. For a heat treatable grade they have excellent spot and fusing weldability and can be furnace brazed. They can be easily anodized.

7000 Series

Alloys in this series have the highest strength of all the series. Zinc is the primary alloying addition. These alloys have excellent fatigue properties. In the T6 condition fracture toughness can be inferior to other alloys. Alloys in series can be spot welded but not fusion welded. If corrosion is a concern, these alloys should be anodized, primed, painted or protected with some type of chemical film.
