5083 H116 Aluminum Properties
5083 H116 Corrosion Resistance
5083 H116 aluminum alloy has excellent corrosion resistance, performing particularly well in marine environments. Its natural oxide film provides a corrosion rate of only 0.02 mm/year in a 3.5% NaCl solution, which is two orders of magnitude lower than ordinary carbon steel.
5083 H116 Workability
Weldability
Excellent weldability, can be welded by conventional methods with minimal loss of post-weld strength. The use of 5356 or 5183 filler wire is recommended, and surfaces should be cleaned before welding.
Formability
Good cold forming performance, but excessive deformation should be avoided to prevent stress concentration. In the H32 temper, the bend radius is only 1.5 times the plate thickness, allowing for complex curved surface forming.
Machinability
Cutting force is reduced by 30% compared to 7075 aluminum alloy, and tool life is doubled. Suitable for various machining processes with high efficiency.
Heat Treatment Adaptability
Annealing temperature is 415℃, which can improve machinability through annealing. It has good thermal stability and maintains good mechanical properties even under high-temperature environments.
Surface Treatment Adaptability
The anodized film thickness can reach 25μm, with hardness exceeding 300HV, making it particularly suitable for applications requiring both decorative and protective properties. It is also suitable for various surface treatment processes such as spraying and electroplating.

5083 H116 Bend Radius
Bend radius refers to the inner radius of the bent section of a material during the bending process. For 5083 H116 aluminum alloy, its bend radius is mainly affected by the following factors:
Material Thickness
The thicker the material, the larger the required bend radius.
Temper
The H116 temper has higher hardness, requiring a larger bend radius.
Bending Direction
Bending along the rolling direction (grain direction) is easier to form, while bending perpendicular to it is more prone to cracking.
Bending Angle
The larger the bending angle, the larger the required bend radius.
Specific bend radius requirements for 5083 H116:
| Material Thickness (mm) | Bend Angle | Minimum Bend Radius (mm) |
| ≥1.5-3.0 | 90° | 3.0t (t = plate thickness) |
| 3.0-6.0 | 90° | 2.5t |
| 6.0-12.5 | 90° | 4.0t |
| 12.5-40.0 | 90° | 89 (fixed value) |
For 180° bends, the minimum bend radius of 5083 H116 aluminum alloy is about 2 times that of the 90° bend radius. It should be noted that these values are for reference only, and actual applications may require adjustment based on specific processes and requirements.
