| Param | Value |
| Machinability | Machinability of AL 3105 is fair. Oil lubricants should be used for all machining operations. Machinability of the alloy when in the harder (H) tempers is improved over machining in the annealed (O) condition. |
| Forming | The forming characteristics of the alloy are very good by all conventional processes regardless of temper. Bend radii should be in the one thickness to 2 t range for annealed, H12, H14 and H16 tempers. The H18 temper requires bend radii of2 to 7 t, depending upon thickness of the material. |
| Welding | Weldability of this alloy is excellent by all commercial techniques. Arc welding is preferred for the best results. |
| Heat Treatment | A non-heat treatable alloy. |
| Hot Working | The hot working range (as for forging) is 205°C to 372°C. In that range the alloy is easily hot worked. |
| Cold Working | The cold working characteristics of AL 3105 are very good, even in the harder cold worked tempers. Bend radi for sheet up to 1/16″ thick vary from 1/2 to one t for all tempers. |
| Annealing | Annealing from a cold worked condition may be accomplished at 345°C followed by air cooling. |
| Aging | Not applicable to this alloy. |
| Hardening | Hardens as a result of cold working only. |

1. What is 3105 grade aluminum?
A 3105 grade aluminum is an aluminum alloy with a small amount of manganese (0.3%) and magnesium (0.3%) added for increased strength.
2. What is the difference between 5052 and 3105 aluminum?
The difference between 5052 and 3105 aluminum is that 5052 contains higher amounts of magnesium and chromium, offering superior strength and corrosion resistance compared to 3105.
3. What is the difference between 3003 and 3105 aluminum?
The difference between 3003 and 3105 aluminum is that 3105 contains additional magnesium, providing slightly higher strength than 3003.
4. What is the price of aluminium 3105?
The price of aluminum 3105 varies depending on market conditions, quantity, and supplier, but generally, it is priced competitively within the range of common aluminum alloys.
5. What is the difference between 3003 H14 and 3105 H24?
The difference between 3003 H14 and 3105 H24 is that 3003 H14 is strain-hardened and partially annealed, while 3105 H24 is strain-hardened and stabilized, providing better formability and corrosion resistance.
