What-is-the-difference-between-5083-H111-and-5083-H112-in-aluminum-alloy-sheet.pdf
The designations 5083 H111 and 5083 H112 refer to two different temper conditions of the 5083 aluminum alloy, each offering unique mechanical properties suited for specific applications. Below is a clear comparison of the two:
5083 H111 Aluminum Plate
Temper Description:
The H111 temper indicates that the aluminum alloy has been slightly strain-hardened during manufacturing to achieve a stable, low-strength condition with excellent ductility.
Properties:
Outstanding workability and formability
Excellent corrosion resistance, particularly in marine and chemical environments
Suitable for applications that require extensive forming or bending operations
Typical Applications:
Ship and boat hulls
Marine fuel tanks
Pressure vessels
Structural components where formability and corrosion resistance are critical
5083 H112 Aluminum Plate
Temper Description:
The H112 temper represents an alloy that has undergone strain hardening and partial annealing, providing higher strength while maintaining good formability and corrosion resistance.
Properties:
Slightly higher strength than H111 due to strain hardening
Retains good corrosion resistance
Moderate formability, suitable for fabrication and welding
Typical Applications:
Offshore and shipbuilding structures
Pressure tanks and chemical containers
Load-bearing marine components
General engineering parts that require a balance of strength and corrosion resistance
Key Differences Between 5083 H111 and H112
| Feature | 5083 H111 | 5083 H112 |
|---|---|---|
| Strength | Lower | Slightly higher |
| Ductility | Higher, easier to form | Moderate |
| Formability | Excellent | Good |
| Corrosion Resistance | Excellent | Excellent |
| Typical Use | Hulls, tanks, vessels requiring deep forming | Structural and welded parts needing more strength |
Summary
Both 5083 H111 and 5083 H112 aluminum plates from GNEE, a leading Chinese aluminum supplier, offer excellent corrosion resistance and reliable weldability, making them ideal for marine, pressure vessel, and structural applications.
Choose H111 when maximum ductility and forming performance are required.
Choose H112 when slightly higher strength is preferred without compromising corrosion resistance.
GNEE Aluminum provides both tempers in various thicknesses and dimensions to meet diverse project needs in shipbuilding, transportation, and industrial fabrication.
