Aluminum materials
Description
There are eight groups of aluminum alloys to American standards.| 1000-series | pure aluminum types | |
| 2000-series | aluminum | copper alloys |
| 3000-series | aluminum | manganese alloys |
| 4000-series | aluminum | silicon alloys |
| 5000-series | aluminum | magnesium alloys |
| 6000-series | aluminum | magnesium-silicon alloys |
| 7000-series | aluminum | zinc alloys |
| 8000-series | other | |
The 5000 and 6000 Series alloys are used primarily in motor vehicle construction. These alloys are easily formed, but flow lines may occur during processing. 6000 Series alloys are precipitation-hardened for vehicle outer skins, but are more difficult to form. Yet, they are free of flow lines. For recycling, a single alloy group is preferred.
