Advantages of using Aluminium
• Light weight - approximately one-third the density of steel
• Strength - some alloys can be substantially strengthened by work or by heat treatment
• Workability - easily formed, machined and welded
• Corrosion resistance - varies depending on the alloy and the best resist marine exposure
• Non-toxic - often used in contact with food
• Non-magnetic and non-sparking
• Electrical conductivity - high
• Thermal conductivity - high
• Reflectivity - bright finish options available.
Specification
Choudhary Metal Distributor Stock Aluminium flat rolled product is most commonly specified
to ASTM B209M. Product designated as plate for ship building in very specific alloys and tempers
in compliance with ASTM B928M.
Alloy Code Derivative

Understanding an Alloy code
an alloy code is made up of 4 digits e.g. 5052 where:
• 5 = major alloying element i.e. magnesium
• 0 = Indicates changes to minor alloying elements i.e. no changes to original alloy since it
was introduced
• 52 = Alloy identification number i.e. identifies the chemical composition of this alloy

Heat Treatable and Non-heat Treatable Alloys
| Alloy |
Treatable/Non-treatable |
| 1. |

| 2. |

| 3. |
Non-heat treatable |
| 5. |
Non-heat treatable |
| 6. |
Heat treatable |
| 7. |
Heat treatable |
Non-heat treatable alloys can be hardened by cold work. The degree of work hardening is
designated by the Temper. Heat treatable alloys (the 2000, 6000, and 7000 series) are able to be
solution treated and then age-hardened.
Temper Designation Systems
H Tempers
| Temper |
Hardness |
| 0 |
Soft |
| H?2 |
1/4 hard |
| H?4 |
1/2 hard |
| H?6 |
3/4 hard |
| H?8 |
Hard |
Where "?" can be read as:
1 = As rolled - no final anneal e.g. H12
2 = Strain hardened and then partially annealed e.g. H24
3 = Strain hardened and then stabilised (at a lower temperature) e.g. H34
Three-Digit H Tempers
For marine applications there are specific tempers in select high magnesium
alloys. Atlas stock is of alloy 5083, usually in H116 temper. An alternative is H321 with
virtually identical properties. H116 tempers are strain hardened as final operations and H321
tempers are thermally stabilized.
