What is Aluminum Grade 3105?
Aluminum grade 3105 is an aluminum-magnesium alloy containing 0.5% magnesium and 0.3% copper. It is a non-heat treatable alloy, which means it cannot be hardened by heat treatment. Instead, it acquires its strength and other desirable properties through cold working or strain hardening.
Features and Properties of Aluminum Grade 3105 include :
- Good deep drawing performance : the deep drawing performance of 3105 o aluminum plate is greater than that of 3105 h26 state, and the deep drawing performance of 3105 aluminum alloy plate before low temperature treatment is better than that of h24.
- High formability : 3105 aluminum plate has high plasticity in the annealed state, good plasticity in semi-cold work hardening, and low plasticity in cold work hardening.
- Good welding characteristics : 3105 grade aluminum is easy to weld and can be joined using a variety of welding techniques.
- Good corrosion resistance, good anodic oxidation, non-toxic and recyclable, poor machinability, etc.

3105 Aluminum Plate Performance Informations
| 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. |
