| PRODUCT DATA of AA5052 |
| Material | AA5052 |
| General Information | Aluminum 5052 is a non heat treatable "strain-hardening" type aluminum alloy. The various tempers are produced by cold working. As the hardness of the temper increases, the alloy exhibits increasing strength along with decreasing elongation. The fatigue endurance limit is higher than that of most wrought aluminum alloys |

| Machinability | This alloy has relatively fair machinability. It is easier to machine in the hard temper than as annealed and the quality of finish is better if machined in the hard condition. Oil lubricants should be used for machining, except that very light cuts may be done dry. |
| Welding | This alloy is readily welded by conventional methods |
