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

Champak Industries 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

Alloy series Major alloying element
1. Pure aluminium (99.0% and greater)
2. Copper is major addition
3. Manganese is major addition
4. Silicon is major addition
5. Magnesium is major addition
6. Magnesium and silicon are major additions
7. Zinc is the major addition
8. Other Alloys

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

Alloy Code derivative used in Rolled Products

Alloy Example Alloy
1. 1145
3. 3003
5. 5052

Heat Treatable and Non-heat Treatable Alloys

Alloy Treatable/Non-treatable
1. Non-heat treatable
2. Heat treatable
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.
