| Characteristics | 5083 H111 | 5083 H112 |
| Heat Treatment and Stress Relief | Simple annealing to remove processing stresses | Subjected to rigorous heat treatment and stress relief |
| Mechanical Properties | Relatively lower strength and hardness, with good machinability | Higher strength and hardness, with better mechanical performance |
| Applications | Suitable for components with lower strength requirements, such as hulls | Suitable for high-load applications, such as structural components |
| Performance Stability | Performance may vary slightly | More stable and consistent performance |
1. Heat Treatment and Stress Relief
H111: This temper typically refers to a simple annealing process primarily aimed at removing stresses induced during processing. H111 aluminum alloys are usually not heavily hardened, resulting in slightly lower mechanical properties compared to H112. However, H111 offers good machinability and sufficient strength.
H112: This temper generally indicates a more rigorous heat treatment and stress relief process. Compared to H111, H112 provides higher strength and better mechanical properties. H112 aluminum alloys undergo treatment after processing and forming to optimize their performance.
2. Mechanical Properties
H111: Mechanical properties are relatively lower and are used in applications with less demanding requirements. Its strength and hardness are lower, but it offers good ductility and formability.
H112: Due to its more stringent heat treatment and stress relief processes, H112 aluminum alloys have higher tensile and yield strength, making them suitable for higher load applications.
3. Applications
H111: Suitable for applications where strength requirements are not particularly high, such as hulls and other corrosion-resistant components that do not endure extreme mechanical loads.
H112: Suitable for applications requiring higher strength and better mechanical performance, such as structural components subjected to significant loads.
4. Performance Stability
H111: Performance may vary slightly, as H111 aluminum alloys are not subjected to particularly strict control.
H112: Performance is more stable and consistent, making it suitable for demanding engineering applications.
