Other properties for 3105 aluminum alloy metal
| Principal Design Features | This is an essentially 98% pure aluminum alloy with minor additions for strength. It is not hardenable by heat treatment. Corrosion resistance, formability and welding characteristics are excellent. |
| Applications | Commonly used in the manufacture of residential siding, mobile homes, and rain carrying goods. Is commonly used in sheet metal work. |
| 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 of 2 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 | This alloy does not respond to heat treatment except for annealing during cold working. |
| Forging | Forging, if required, may be done in the range of 950 to 700 F. |
| Hot Working | Hot working may be accomplished at 700 to 400 F. |
| Cold Working | The cold working characteristics of AL 3105 are very good, even in the harder cold worked tempers. Bend radii 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 650 F followed by air cooling. |
| Aging | Not applicable to this alloy. |
| Tempering | Not applicable. |
| Hardening | Hardens to the H12, 14, 16, 18 or 25 tempers only by cold working. |
| Other Physical Props | Electrical conductivity 41% of copper. |
| Other Mechanical Props | Typical shear strength values are: H14 15 ksi and H16 17 ksi. |
3105 aluminum coil sheet has high plasticity in the annealing state, in the semi cold hardened, the plasticity is still better, it has low plasticity, good weld-ability and poor cutting properties in cold hardening state.

3105-H14 Aluminum vs. 3105-H24 Aluminium
Both 3105-H14 aluminum and 3105-H24 aluminum are variants of the same material. They share alloy composition and many physical properties, but develop different mechanical properties as a result of different processing.
3105-H24 aluminum is 3105 aluminum in the H24 temper. To achieve this temper, the metal is strain hardened, and then partially annealed, to a strength that is roughly halfway between annealed (O) and full-hard (H28).
