Aluminum 3003 wrought alloy sheet O H14 Good weldability AMS 4006
QQ-A-250/2
Description
3003 aluminium alloy is a commercially pure aluminium which boasts
excellent mechanical properties and is a widely used aluminium
throughout industry. It is a medium strength alloy with very good
resistance to atmospheric corrosion. The alloy boasts improved
mechanical properties when compared with 1000 series alloys and is
20% stronger than 1100.

Among the 3xxx Aluminum alloys, the amount of 3003 alloy is the
largest. Aluminum 3003 alloy sheet is easy to process, it can be
roolled with color paint on the surface of raw aluminum to make
curtain wall panels for various decoration purposes.
Aluminum 3003 has better price than 5052 alloy, with its good
weldability, some truck fuel tank material manufacturer use alloy
3003 H24 to produce pressure-free baffle instead of 5052, so they
can reduce the cost without affecting use.
Possible Alternative Alloys
| Alloy | Why it might be chosen instead of 3003 |
| 5005 | Bright (decorative) anodising finish is required. |
| 5052 | Higher strength required and less bright finish is acceptable. |
| 5083 | Higher strength or improved corrosion resistance required,
particularly for ship hull applications. |
