The designations 5083H111 and 5083H112 refer to different temper conditions of the aluminum alloy 5083. Here’s a breakdown of each:
- 5083H111:
- Temper Condition: This temper is characterized by a relatively low strength and excellent ductility. It indicates that the aluminum alloy 5083 has undergone a specific process to achieve a stable temper with a low degree of strain hardening.
- Properties: In the H111 temper, 5083 aluminum alloy has good workability and retains excellent corrosion resistance. It is typically used in applications where forming and/or bending operations are required and where a high degree of corrosion resistance is necessary, such as in marine environments.
- Typical Applications: Marine hulls, tanks, pressure vessels, and other applications where formability and corrosion resistance are critical.
- 5083H112:
- Temper Condition: This temper is slightly different from H111. It indicates that the aluminum alloy 5083 has undergone a process to achieve a stable temper with a certain degree of strain hardening. H112 temper is specific to alloys that have been strain-hardened and then undergo a process to partially anneal them.
- Properties: Compared to H111, H112 temper typically offers slightly higher strength due to the strain hardening process. It retains good formability and corrosion resistance, though not as ductile as H111.
- Typical Applications: Similar to H111, 5083H112 is used in marine applications, pressure vessels, and structural components where moderate strength combined with good formability and corrosion resistance is required.
Key Differences:
- Strength: 5083H112 typically has slightly higher strength compared to 5083H111 due to the strain hardening process involved.
- Ductility: 5083H111 is more ductile and easier to form compared to 5083H112.
- Applications: Both tempers are used in similar applications where corrosion resistance is crucial, but the choice between H111 and H112 depends on the specific balance of formability and strength required for the application.
In summary, while both 5083H111 and 5083H112 are temper conditions of aluminum alloy 5083 offering good corrosion resistance, the H112 temper provides slightly higher strength due to strain hardening, whereas the H111 temper emphasizes excellent ductility and ease of forming.
