| Aluminum alloy |
5052 (A5052P) |
It is the most typical non-heat treatment alloy and has good corrosion resistance and weldability. |
● |
|
| 6063 (A6063S) |
It is the most versatile extruded material among aluminum alloys. Although it is inferior in strength to A6061, it has excellent corrosion resistance and surface treatment. |
