Comparison of Aluminium 1050 H24 with Other Tempers
- H14 (semi-hard): Higher strength but lower ductility.

| Comparison Items | Aluminium 1050 H24 | Aluminium 1050 H14 (semi-hard) | Aluminium 1050 O (annealed) |
| Processing Method | Cold-work hardened and partially annealed to balance strength and ductility. | Cold-work hardened but not annealed, leading to higher strength and lower ductility. | Fully annealed to achieve the softest state, providing maximum ductility. |
| Strength | Moderate; strength is between H14 and O temper, suitable for applications requiring both strength and workability. | Higher strength than H24; ideal for applications needing greater resistance to deformation. | Lowest strength but excellent flexibility, ideal for highly plastic forming processes. |
| Ductility | Good ductility, though slightly lower than O temper, allowing for bending and forming. | Lower ductility than H24, making it less suitable for large bends or deep drawing. | Highest ductility, ideal for complex stamping, bending, and deep drawing. |
| Suitable Applications | Suitable for applications requiring both moderate strength and good formability, such as architectural decoration, signage, and industrial uses. | Ideal for applications needing higher rigidity but not extreme forming properties, such as structural components and mechanical parts. | Best for applications requiring extreme plasticity, such as deep-drawn products and extrusion forming. |
