1100 H14 aluminum and 1100-H24 aluminum both belong to the 1100 series of aluminum alloys. These alloys are widely used in various fields such as aerospace, automotive, construction, and electronic devices due to their excellent corrosion resistance and good processing performance. Although they have the same alloy composition (primarily 99% aluminum), their mechanical properties differ due to different processing methods (i.e., heat treatment and cold working). The main differences between 1100-H14 and 1100-H24 are in ductility, tensile strength, and elasticity.
1100 H14 aluminum and 1100-H24 aluminum are variants of the same material. They have the same alloy composition and many physical properties, but they exhibit different mechanical properties due to different processing techniques.
The following table clearly shows the differences between 1100-H14 aluminum alloy and 1100-H24 aluminum alloy in various mechanical properties.
| Property | 1100-H14 Aluminum Alloy | 1100-H24 Aluminum Alloy |
| Elongation at Break | 1100-H14 aluminum alloy has better ductility and can withstand more tensile stress under greater deformation. This makes it ideal for processing techniques that require high plasticity and elongation, such as deep drawing or complex forming processes. | 1100-H24 aluminum alloy has lower ductility and is suitable for applications that do not require large deformation, making it ideal for simpler processing processes. |
| Tensile Strength (Ultimate Tensile Strength) | 1100-H14 aluminum alloy has slightly lower tensile strength, making it suitable for applications with relatively low strength requirements. It strikes a balance between strength and toughness, making it ideal for scenarios that require good formability. | 1100-H24 aluminum alloy has slightly higher tensile strength, providing better strength performance. It is suitable for applications that require higher material strength, especially in structural load-bearing scenarios. |
| Fatigue Strength | 1100-H14 aluminum alloy has lower fatigue strength, making it suitable for applications with light or minimal vibration. It performs better in environments that require some degree of ductility. | 1100-H24 aluminum alloy has slightly higher fatigue strength, allowing it to withstand higher cyclic loads. It is suitable for environments with prolonged vibration or repeated loading. |
| Elasticity | 1100-H14 aluminum alloy has a higher ultimate fracture energy, meaning it can better absorb external impacts or loads and has stronger energy absorption capacity. It is suitable for impact or heavy load environments. | 1100-H24 aluminum alloy has lower ultimate fracture energy, making it less effective in energy absorption compared to 1100-H14. It is more suitable for applications with smaller or more stable loads. |
1100-H14 aluminum alloy is suitable for applications that require high ductility and energy absorption, while 1100-H24 aluminum alloy is better for applications that require higher strength and fatigue resistance.
